1 Introduction

1.1 EAS Transport Planning has been commissioned by Croudace Homes to prepare a Transport

Assessment (TA) for a proposed future development off Thieves Lane in Hertford, East Herts District, on

Greenfield Land.

1.2 The site is bordered by Welwyn Road to the north, Thieves Lane to the east and farmland and woodland

to the west and south. The site is an urban extension and the east and northern boundaries are

established urban areas forming the Sele Farm ward. A location plan forms Appendix A.

1.3 For transport review purposes this TA is based on a proposed development of 280 houses with parking

allocation in accordance with the district policy. The site will comprise of a mix of 2 to 4 bedroom houses

although the final content is still to emerge.

1.4 Discussions have been held with Hertfordshire County Council (HCC) as highway authority following a

considerable amount of background surveying and modelling work of local junction capacity.

Hertfordshire have stated that they would not object to this development proposal. Appendix B contains

a meeting note in email form together with other discussion related emails. This document contains all

the discussions with HCC and the additional requirements of HCC following the discussions.

1.5 This TA has been prepared with regard to the DfT Guidance on Transport Assessments (March 2007).

1.6 The contents of this TA based on the agreed scope are:

• Section 2 – sets out the pre-application discussion with HCC

• Section 3 – sets out the policy context;

• Section 4 – describes the existing site function and sets out the baseline conditions;

• Section 5 – is a review of facilities near to the site and describes the available public transport.

• Section 6 – describes the site access, potential layout and function.

• Section 7 - describes the existing and expected transport impacts due to the development trips; and the detailed analysis of modelling undertaken at the nearby junctions as well as the surveys undertaken.

• Section 8 – summarises and concludes this report.

2 Pre-application Consultation, HCC Highways

2.1 As described above EAS completed a range of surveys and modelling and discussed this at a meeting

with officers of HCC in January 2013. The full set of email records form Appendix B. The email note of

the meeting setting out the additional discussion is included below for ease of reading;

“Thanks you for your time last Tuesday when we met at County Hall to discuss the proposed residential

development off Thieves Lane in Hertford for circa 280 units with Croudace Homes

I understand that you will be happy to see a draft of a TA in due course in advance of any application so

that we can discuss any issues and work together on this project.

With respect to the work we have done so far your colleague will be reviewing the modeling but generally

you are content with the approach we have taken and the trip rate of circa 0.6 we have used rather than

the lower one observed at Turpins Close. You would like us to undertake a sensitivity test of assignment

based on the 2011 Census (work location) when this is available I( I believe soon) and compare this to

the findings of our site observations.

We will of course issue all the modeling as part of our TA including the PM ARCADY tests for the A414

junction and both AM and PM for the Welwyn Road junction.

We discussed the approach to access and agreed that this can all be solved in due course and that one

or two access points may be appropriate for the site but that it could operate with one access, in which

case an emergency access would be required. Access layouts should meet the MfS standards of

visibility and consider the position of existing junctions. You described HCC approach that they now

adopt the main routes only and any short cul- de-sacs generally are not adopted.

We discussed any traffic schemes or developments that we should consider as part of the assessment

but you confirmed that there were none in proximity which would impact upon our work.

We will of course include the relevant Local and National Policy within our document to ensure that we

comply on transport grounds and you suggested we review the Hertford and Ware Urban Transport Plan

as well.

You discussed the HCC relationship with Croudace which is good and that you would require a planning

obligation for transport so that benefits can be made strategically.

I believe you asked that we review accident patterns at the A414 roundabout just to the west of the rail-

bridge, we will be reviewing accident patterns as part of our TA and so will extend to this junction as well.

Page 3

This is all I can recall, so please add if there is anything else. Overall a positive meeting and I believe

you confirmed you would not have an objection on highway grounds as things currently stand.

I would be grateful if you would confirm this is a correct interpretation of our meeting as soon as possible

and please feel free to call with any questions/clarifications.”

2.2 HCC subsequently confirmed the above meeting note.

3 Policy Review

Introduction

3.1 This section reviews the latest relevant policy documents both Nationally and Locally

National Planning Policy Framework

3.2 Paragraph 14 of the NPPF states:

“At the heart of the National Planning Policy Framework is a presumption in favour of sustainable

development, which should be seen as a golden thread running through both plan-making and decision-

taking.”

3.3 Paragraph 17 of the National Planning Policy Framework (NPPF) sets out 12 core planning principles

including core principle 11 which states that planning should:

“actively manage patterns of growth to make the fullest possible use of public transport, walking and

cycling, and focus significant development in locations which are or can be made sustainable.”

3.4 Section 4 of the NPPF on transport includes advice on Transport Assessments at paragraph 32:

“All developments that generate significant amounts of movement should be supported by a Transport

Statement or Transport Assessment. Plans and decisions should take account of whether:

● the opportunities for sustainable transport modes have been taken up depending on the nature and

location of the site, to reduce the need for major transport infrastructure;

● safe and suitable access to the site can be achieved for all people; and

● improvements can be undertaken within the transport network that cost effectively limit the significant

impacts of the development. Development should only be prevented or refused on transport grounds

where the residual cumulative impacts of development are severe”

3.5 Paragraphs 35 and 36 of the NPPF discusses locating development and use of Travel Plans

respectively:

“Plans should protect and exploit opportunities for the use of sustainable transport modes for the

movement of goods or people. Therefore, developments should be located and designed where practical

to

● accommodate the efficient delivery of goods and supplies;

Page 5

● give priority to pedestrian and cycle movements, and have access to high quality public transport

facilities;

● create safe and secure layouts which minimise conflicts between traffic and cyclists or pedestrians,

avoiding street clutter and where appropriate establishing home zones;

● incorporate facilities for charging plug-in and other ultra-low emission vehicles; and

● consider the needs of people with disabilities by all modes of transport.

A key tool to facilitate this will be a Travel Plan. All developments which generate significant amounts of

movement should be required to provide a Travel Plan.

3.6 Paragraph39 discusses parking policy:

If setting local parking standards for residential and non-residential development, local planning

authorities should take into account:

● the accessibility of the development;

● the type, mix and use of development;

● the availability of and opportunities for public transport;

● local car ownership levels; and

● an overall need to reduce the use of high-emission vehicles.”

East Herts Local Plan (EHLP)

3.7 The Secretary of state confirmed on 22nd March 2010 a range of saved policies from the 2007 EHLP.

Relevant policy extracts are set out below in italics, responses are in plain text;

TR1 Traffic Reduction in New Developments

Developments generating additional traffic will be required to incorporate measures, commensurate with

the scale of additional traffic generated, to ensure that alternative transport options to the private motor

vehicle are available to the users of the site. Such measures may include:

(a) the extension and improvement of pedestrian links;

(b) cycle paths and facilities;

(c) improvements to the passenger transport network which should include bus and/or rail facilities,

either directly to the site or in close proximity to it (i.e. within 400 metres maximum walk distance), and

Page 6

may involve an extension to existing infrastructure (e.g. additional cycle paths, bus shelters) and/or

enhancements to the existing bus network;

(d) the provision of moorings alongside navigable waterways (as appropriate); to be achieved via the

imposition of conditions and the use of planning obligations (or as subsequently revised) as appropriate

to the individual characteristics of the site.

3.8 The development proposes extensions to footways at the site boundary and refuges to access facilities.

Internally the layout design has yet to be agreed, but the site will be laid out to benefit alternative

transport modes as far as practicably possible.

TR3 Transport Assessments

Developments that are likely to generate significant movement and travel demand will require the

submission of a Transport Assessment to accompany the planning application, which should meet the

criteria contained in Hertfordshire County Council’s Roads in Hertfordshire – Design Guide, 2001 (or as

subsequently superseded, by the local highway authority)

3.9 Hence the production of this document.

TR7 Car Parking – Standards

Car parking provision for new development proposals will be assessed in accordance with the District

Council’s car parking standards (which should be taken as maximum standards), including coach, cycle

and powered two-wheeler provision, as set out at Appendix II. The actual provision made will be

determined on a site-specific basis having regard to the proposed use, location, and availability of, or

potential for access to, modes of transport other than the private car in accordance with the Council’s

SPD ‘Vehicle Parking Provision at New Development’.

3.10 Parking on site will be policy compliant.

TR12 Cycle Routes – New Developments

Where possible, the design of new developments will be required to include coherent, safe, convenient,

direct, comfortable, attractive routes and facilities for cyclists and pedestrians. Where practicable

opportunities exist or can be created, access routes into and through the site for cyclists and pedestrians

should be formed separate from roads, particularly if this would create an advantage over motorised

transport in the distance and time needed to travel to local facilities and services and/or improve the

wider cycle network. Where appropriate, developer contributions (or as subsequently revised) will be

expected to improve pedestrian and cycle routes associated with the use of the site.

3.11 Internally the layout design has yet to be agreed, but the site will be laid out to benefit alternative

transport modes as far as practicably possible.

Page 7

TR14 Cycling – Facilities Provision (Residential)

Applications for new residential developments should, where appropriate, demonstrate provision of

sufficient cycle storage facilities for occupants of new dwellings to enable cycle usage to become a

realistic option to the use of private motorized transport. Such facilities should include appropriate

secure, covered, waterproof storage facilities and be provided either within the curtilage of the dwelling

or, for example, in the case of flats, within a communal area, provided that such facilities are easily

observed and accessible.

3.12 Secure covered cycle storage will be incorporated into the development.

TR18 Home Zones

The implementation of Home Zones, involving appropriate speed limits and traffic calming measures to

ensure priority is given to the use of residential streets for the benefit of pedestrians, cyclists and local

residents, will be supported provided that they are of good quality design and consistent with and/or

enhance the character, landscape, and residential amenity of the area.

3.13 The development will be design to MfS standards which incorporates ‘Home Zone’ themes.

Hertford and Ware Urban Transport Plan

3.14 At the request of HCC the Hertford and Ware Transport Plan has been reviewed. Appropriate elements

are contained below. Extracts from the transport plan are in italics, responses are in plain text.

4.4.1 The County Council’s vision for Hertfordshire’s transport over the next twenty years is ‘to provide a

safe, efficient and affordable transport system that allows access for all to everyday facilities. Everyone

will have the opportunity and information to choose the most appropriate form of transport and time of

travel. By making best use of the existing network we will work towards a transport system that balances

economic prosperity with personal health and environmental well being.’

3.15 This is the basis of all transport policy which all development must consider.

4.4.2 The LTP has nine objectives set out under the government’s shared priorities of safety,

congestion, accessibility, air quality and quality of life. The objectives, listed under the shared priorities,

include:

Safety

– To improve safety for all by giving the highest priority to minimising the number of collisions and

injuries occurring as a result of the transport system.

3.16 All access points will be designed to meet appropriate standards, there are opportunities (described later)

Page 8

to improve crossing of roads for pedestrians.

Congestion

– To obtain the best use of the existing network through effective design, maintenance and

management.

– To manage the growth of transport and travel volumes across the county, and thereby secure

improvements in the predictability of travel time.

– To develop an efficient, safe, affordable and enhanced transport system which is attractive, reliable,

integrated and makes best use of resources.

3.17 As will be seen later existing travel patterns exist which combat congestion near to the site via peak

spreading. Any additional traffic from the site is shown to be imperceptible amongst the back ground

traffic.

Accessibility

– To develop a transport system that provides access to employment, shopping,education, leisure and

health facilities for all, including those without a car and those with impaired mobility.

– To ensure that the transport system contributes towards improving the efficiency of commerce and

industry and the provision of sustainable economic development in appropriate locations.

3.18 The location of the site has been shown to be accessible being located adjacent to many bus routes and

close to three schools, a local shopping area and within walking distance to Hertford North Station and

Town Centre.

Quality of Life

– To raise awareness and encourage use of more sustainable modes of transport through effective

promotion, publicity, information and education.

– To reduce the need for the movement of people and goods through integrated land use planning.

3.19 The location of the site would allow integration to existing infrastructure, services and education and

employment. All units would have secure cycle parking. A travel plan is not required as clarified in policy

TR4 of the EHLP.

Bus Strategy

4.4.8 The bus strategy’s objectives contribute to the overall LTP shared priorities of safety, congestion

management, accessibility and quality of life by:

Page 9

_ Providing an effective and efficient network of bus services as a travel mode which passengers will

choose to use;

_ Reviewing the network with others to ensure resources are used to best effect;

_ Improving bus punctuality through commercial partnerships and better management of the highway

network;

_ Developing accessibility to employment, shopping, education, leisure and health facilities by effective

design of the bus network, the use of less conventional approaches and securing maximum external

funding;

_ Continuing to improve vehicle quality and associated infrastructure at bus stops and interchanges to

increase access to the network by those with impaired mobility; and

_ Raising awareness and encouraging the use of bus services through improved information, marketing

and branding.

3.20 The location of the development site adjacent to many bus routes will increase the use of these routes

and therefore their viability.

Cycling Strategy

4.4.10 The Cycling Strategy documents mentions that Hertfordshire has the lowest levels of cycling to

work in the East of England region. The primary purpose of the cycling strategy is “to encourage more

people to cycle more often, and involve and support other stakeholders in doing the same.”

3.21 All units will have secure cycle parking.

Road Safety Plan

4.4.15 The Road Safety Plan is to deliver the LTP objective of improving safety for all by giving the

highest priority to minimising the number of collisions and injuries occurring as a result of the transport

network. It is to deliver Hertfordshire’s casualty reduction targets:

to reduce the number of people killed or seriously injured in road collisions to no more than 600 by

2010; to reduce the number of children killed or seriously injured in road collisions to no more than 56 by

2010; and no increase in slight casualties (5,509).

4.4.16 It should be noted that the safety targets (KSI and slight) have their own ranking system. Any

scheme the UTP may develop will only have safety as a secondary target and a UTP scheme cannot be

funded by a safety-related target.

Page 10

3.22 A review of personal injury road accidents close to the site has been undertaken, it is shown that the

level of accidents in the vicinity of the site is low.

A414

5.2.1 Key congestion hotspots in Hertford are cited as being mainly on the A414 on its route through the

town and at its connection with the A10. The Bluecoats and Mill Road junctions are often identified as

areas causing the most significant delays to traffic, both in the morning and evening peak periods.

Congestion also occurs frequently at the Castle Street junction with Parliament Square and at the

junction of Hale Road with Pegs Lane (County Hall and Wallfields roundabout). The proximity of the M25

to the study area also can lead to these problems being exacerbated when disruption occurs on the

motorway network.

3.23 This matter was considered at the outset. It was shown that the level of peak hour trip rates from the site

is low and traffic assigned away from the A414 (Hertford). Nevertheless this matter has been discussed

with HCC as the development could not solve A414 issues which would need a strategic solution.

Contributions will be sought from the developer towards other transport improvements to support

alternative travel options.

Summary

3.24 Numerous transport policies have been considered both nationally and locally. It is clear that the site will

be fully policy compliant.

Page 11

4 The Existing Site Function and Base Line Conditions

Introduction

4.1 This section describes the existing site function and the existing (baseline) travel characteristics of the

area local to the proposed development site.

Site Location

4.2 A plan of the proposed development site in relation to local centres and key facilities is shown in

Appendix C.

4.3 The site is located in the Sele Farm ward off Thieves Lane which forms a junction with the A414

approximately 300m south of the site and the Welwyn Road B1000 at the sites north east boundary. The

A414 is primary route through Hertfordshire linking to the Essex border and beyond to the east and

Hemel Hempstead to the west. More locally it also links the north south routes of the A10 and A1. The

A10 being approximately 3 miles east of the site and the A1 approximately 5 miles west of the site.

4.4 The A414 is therefore of significant strategic importance and this matter was of high consideration

throughout the study.

Existing Site Transport Conditions

4.5 Whilst the site is currently green field land, it is close to the A414. The A414 is a busy dual carriageway

for most of its length in the vicinity of the site although a bottle neck occurs to the east of the Thieves

Lane/A414 roundabout where it passes under a rail bridge and then continues into the Hertford central

area. As the A414 passes Hertford centre there are a number of roundabouts (some part time

signalized) and pedestrian crossing opportunities. As a result this section of the A414, within the

Hertford central area, is congested locally.

Local Travel Characteristics

4.6 To inform the modeling it was considered prudent to determine the peak hour trip rate for existing

residences off Thieves Lane and for this purpose EAS undertook a cordon count of Turpins Close

between 07.30 and 09.30 on a neutral weekday. At the same time EAS also completed a distribution

survey to determine vehicle assignment from Turpins Close. We expected that there would be peak

spreading from these developments in order to avoid the morning periods of congestion on the A414 and

also that the assignment would generally avoid the A414 into Hertford.

4.7 The results of the survey concurred with the expectations, the peak hour two way trip rate was 0.39 and

only 12% of traffic departing from the development in the peak period headed towards Hertford on the

Page 12

A414.

Road Traffic Accidents

4.8 Road Traffic Accident data has been obtained from HCC for the five year period ending November 2012.

4.9 No accidents have occurred with the limits of the site boundary. Two slight accidents have occurred to

the east on Thieves Lane and one slight accident has occurred to the north on Welwyn Road. Eight

slight accidents have occurred at the A414/Thieves Lane roundabout.

4.10 At the request of HCC we have also obtained data for the A414/Campfield Road Roundabout located

just to the west of the rail bridge. Two slight accidents have occurred at this roundabout.

4.11 No serious of fatal accidents have occurred in the study area. This is a very good accident record. The

accident data is included at Appendix D.

Summary

4.12 The site is located within a residential area but forming a greenfield extension to the Sele Farm ward.

4.13 The existing traffic conditions immediately surrounding the site are generally light. However the A414 is

located to the south of the site which is a busy dual carriageway for most of its length; a bottle neck

occurs to the east of the Thieves Lane/A414 roundabout junction causing congestion passing the

Hertford Town Centre area.

4.14 Survey results indicate that local residents avoid using the A414 towards Hertford in the peak periods.

This is typical of travel patterns in urban areas where there is peak spreading.

4.15 There have only been slight traffic accidents occurring in the most recent five year period in the study

area and these are low in number.

Page 13

5 Local Facilities and Public Transport

5.1 The plan attached at Appendix C, illustrates the local facilities with indicative pedestrian walk isochrones

and local public transport links. The site is very well located for accessing facilities by foot or cycle,

including retail, education, health, leisure, and employment.

5.2 Two primary schools and secondary school as well as local shops, a pub and bus stops, are all located

within a 400m walk of the site.

5.3 The local shops consist of;

• Co-op food store

• Fish and chips

• Pharmacy;

• Bakers

• Hairdressers

• Butchers

• Betting Shop

5.4 Hertford North Station is an approximate 900m walk from the site, which is located off North Road. At

this point North Road has marked cycle lanes and the Station has good levels of secure covered cycle

parking.

5.5 The whole of Hertford Town Centre with all amenities is within a 2km walk of the site. 2km is recognized

as a walkable distance.

Rail

5.6 As set out above Hertford North Station is located within 900m of the site but in addition Hertford East

Station is just outside of the Town Centre.

5.7 Hertford North has services to London Kings Cross and Moorgate as well as Stevenage in a northbound

direction. Services to London are generally every 20minutes with an hourly northbound service to

Stevenage.

5.8 Hertford East is at the end of the line for the Hertford Branch of the West Anglia Service; running south

to London Liverpool Street. Connections can be made at Broxbourne to travel northwards to Cambridge.

Two services per hour run from Hertford East Station.

Buses

5.9 The closest bus stops to the site are located on Thieves Lane at the site boundary. Two services pass

Page 14

the site boundary, the 388 and the H3. The 388 runs between Hertford and Welwyn bus station and the

H3 to Hertford North Station. Just to the north east of the site, within 100m of the boundary, a range of

additional services can be picked up. These run to various destinations including Harlow and Heathrow;

Hertford East and North Bus Stations, Broxbourne and Waltham Cross Train Stations.

5.10 The bus services local to the site are shown on the plan at Appendix E. It is clear that the site is very well

located to public transport services.

Summary

5.11 The site is located at the edge of an existing residential urban area and therefore benefits from the

existing urban facilities and infrastructure but will also add to the local economy and the viability of these

existing facilities.

5.12 The site is in walking distance of the Hertford North Rail Station, Hertford Town Centre and bus services

pass the site frontage. A range of everyday requirements including schools are also very local to the site.

The site is therefore in a very sustainable development location.

Page 15

6 Proposed Site Layout and Function

6.1 The development site will contain approximately 280 residential homes of between 2 and 4 bedrooms

although the final content is to be determined.

6.2 The internal layout is also to be determined although it is possible that a link between Thieves Lane and

Welwyn Road will be formed. The site has generous frontage which can accommodate full visibility

splays. Appendix F contains a drawing which provides a potential option for access points and includes

pedestrian refuge options within Thieves Lane and Welwyn Road.

Proposed Car and Cycle Parking

6.3 Parking would be incorporated into the development in accordance with East Herts District Parking

Policy.

Refuse and Servicing Arrangements

6.4 Refuse facilities will be accessible to each unit. The layout would be designed to accommodate the

refuse collection requirements for East Herts District Council.

Summary

6.5 The internal layout has yet to be determined but it will be constructed to adoptable standards and with

the ethos of the ‘Manual for Streets’ which is adopted as a design guide for Hertfordshire.

6.6 There are many access options available, all will have appropriate visibility splays and access geometry.

Page 16

7 Traffic Modelling Rationale and Results

Local Cordon Survey

7.1 EAS undertook a cordon count of Turpins Close between 07.30 and 09.30 on a neutral weekday. At the

same time EAS also completed a survey to determine vehicle route choice (assignment). It was

expected that there would be peak spreading from the development in order to avoid the worst periods of

congestion on the A414 and also that the assignment would generally avoid the A414 into Hertford.

7.2 The results concur with the expectations, the peak hour two way trip rate was recorded as 0.39 and only

12% of traffic departing from the development in the peak period headed towards Hertford on the A414

(eastbound).

Census (Work Place Destination)

7.3 At the request of HCC we have undertaken a review of the 2011 census to determine ‘work place’

destination from the local area. The results of the data are included at Appendix G. What needs to be

kept in mind is that the census does not tell you;

• the time of the journey, i.e how the journey fits around the peak hour,

• that work place journeys only make up about 30% of all peak hour journeys,

• the route choice.

7.4 The work place locations are also broken down by mode of travel and from this it is likely that 55% would

need to travel east on the A414. The assignment taken to reach the A414 is not possible to determine,

but based on experience and observations it is highly likely that in the most congested periods most

people would choose to travel via Welwyn Road (east) and join the A414 at the North Road roundabout.

This route is generally less congested and has a dedicated left turn slip onto the A414 (east) avoiding

the bottleneck formed by the upstream rail bridge.

7.5 The lack of route choice (assignment) data in the census means that the overall journey to work data

adds no evidence to lend or remove support for the actual route choice observed in the Cordon Survey.

Traffic Surveys

7.6 Traffic surveys were obtained from HCC for the Thieves Lane/Welwyn Road Roundabout. These were

recorded in May 2011.

7.7 A full classified turning count and queue length survey was commissioned for the A414/Thieves Lane

Roundabout, this was competed on 4th

December 2012.

7.8 Both sets of traffic survey data are enclosed as Appendix H.

Page 17

Assignment Model

7.9 Assignment has been prepared based on the actual turning movements at this junction and the two way

movements of Thieves Lane and Welwyn Road rather than the observed assignment from the cordon

survey. The full assignment model was completed using EXCEL. The assignment model information is

contained in Appendix I.

Trip Rates

7.10 The observed two-way Trip Rate from Turpins Close was 0.39. Turpins Close contains of the order of 50

houses and so is a suitable proxy for the future development site. However, for the purposes of being

robust a 50% higher trip rate than the that observed was used i.e a two way trip rate of 0.6.

7.11 This was agreed as appropriate at the pre-application meeting with HCC. As such no further trip rates

have been calculated, but generally a trip rate of 0.6 for a home county site in a sustainable location is

robust.

TRICS

7.12 To validate the observed trip rates from Turpins Close and prove the robustness of using a 0.6 trip rate,

a TRICS assessment has been undertaken. The TRICS assessment included 43 sites ranging from 9 to

372 units throughout England. 19 of the sites were ‘sub-urban’ and 19 ‘edge of town’. 3 were ‘edge of

town centre’ and 2 were ‘neighbourhood centre’.

7.13 The results gave an AM two way peak hour vehicle trip rate of 0.566 and a PM two way peak hour

vehicle trip rate of 0.609. As a result the use of a two way trip rate of 0.6 following observations of 0.39,

is considered appropriate and robust.

7.14 Full TRICS trip rate information is contained at Appendix J.

Future Year Assessment

7.15 No future year assessment has been completed. HCC confirmed (in the meeting note) there were no

other development sites that needed to be considered within the assessment. Since the commencement

of the recession there has been stagnated traffic growth, therefore for the foreseeable future and for a

site where peak spreading is occurring due to congestion, allowing for a future year assessment is not

necessary.

ARCADY Model A414/Thieves Lane Roundabout

7.16 Arcady models for both the AM and PM peak hours for the A414/Hertingfordbury Road/Thieves Lane

roundabouts have been prepared.

Page 18

7.17 Full classified turning data for the A414 R/B was collected on a neutral weekday together with a queue

length survey of all arms. Prior to this the junction was visited on three occasions in the AM peak

specifically to observe the traffic.

7.18 The A414/Thieves Lane junction was observed to work very well and queues are minimal. EAS has

modelled the existing operation of the junction using ARCADY for both the AM and PM periods. The

results closely replicate the existing traffic conditions.

7.19 The likely development generated traffic was then added based on actual turning movements at this

junction rather than the observed assignment from the cordon survey and also using a 50% higher trip

rate than the that observed from the cordon survey for reasons of being robust.

7.20 Consideration was given as how to best model the A414 roundabout as it was clear that the flows into

the roundabout from Hertford are regularised by the signals upstream and the bottle neck caused by the

rail bridge just east of Campfield Road. Thus the flows onto the roundabout are remarkably similar in

each quarter of an hour period. EAS therefore built the model using the ‘Direct Input’ and actual HGV

options rather than the more simple OD TAB and default HGV options.

7.21 The results of the ‘existing’ and ‘with development’ ARCADY models for the AM period are as follows;

ARCADY Model Thieves Lane/Welwyn Road Roundabout

7.24 The same exercise has been undertaken for the Welwyn Road junction. In this instance traffic flow data

was obtained from HCC. The count was undertaken in May 2011 and is therefore recent enough to be

valid.

7.25 The roundabout works well within capacity and continues to do so following the addition of the

development flows.

7.26 The results of this ARCADY assessment for both junctions are enclosed at Appendix K.

Page 20

Summary

7.27 Considerable attention has been given to prepare an accurate model of the junctions closest to the site

including the Thieves Lane/ Welwyn Road and Thieves Lane/A414 roundabout junctions. It is clear that

the models replicate very well the existing traffic conditions and the robust assessment prepared

confirms that the traffic generated by the development will be imperceptible.

Page 21

8 Summary and Conclusion

8.1 For transport review purposes this TA is based on a proposed development of 280 houses with parking

spaces that will be policy compliant. It is a greenfield site but adjacent to an established residential area

forming the Sele Farm ward.

8.2 Considerable pre-application discussion has taken place with Hertfordshire County Council as Highway

Authority and HCC have confirmed that they would have no objection to this application on Highways

Grounds.

8.3 The site is located at the edge of an existing residential urban area and therefore benefits from the

existing urban facilities and infrastructure but will also add to the local economy and the viability of these

existing facilities.

8.4 The site is in walking distance of the Hertford North Rail Station, Hertford Town Centre and bus services

pass the site frontage. A range of everyday requirements including schools are also very local to the site.

The site is therefore in a very sustainable development location.

8.5 The existing traffic conditions immediately surrounding the site are generally light, however the A414 is

located to the south of the site which is a busy dual carriageway for most of its length; a bottle neck

occurs to the east of the Thieves Lane/A414 roundabout junction causing congestion within the Hertford

Town Centre area

8.6 Survey results indicate that local residents avoid using the A414 towards Hertford in the peak periods

and the peak hour trip rates are low. This is typical of travel patterns in urban areas and is indicative of

peak spreading.

8.7 There have only been slight traffic accidents occurring in the most recent five year period in the study

area and these are considered low in number.

8.8 The internal layout has yet to be determined but it will be constructed to adoptable standards and with

the ethos of the ‘Manual for Streets’ which is adopted as a design guide for Hertfordshire.

8.9 There are many access options available, all will have appropriate visibility splays and access geometry.

8.10 Considerable attention has been given to prepare an accurate model of the junctions closest to the site

including the Thieves Lane/ Welwyn Road and Thieves Lane/A414 roundabout junctions. It is clear that

the models replicate very well the existing traffic conditions and the robust assessment prepared

confirms that the traffic generated by the development will be imperceptible.

Page 22

Conclusion

8.11 Transport Policy relevant in East Herts and nationally has been considered. Traffic generated by the

development will be imperceptible. The site is in a sustainable location and will add to the viability of

local services and infrastructure.

8.12 The site provides a highly policy compliant and sustainable residential development opportunity in

transport terms.

Subject: Proposed Development off Thieves Lane Hertford

Dear Vetti, Paul and Dan,

Thanks you for your time last Tuesday when we met at County Hall to discuss the proposed residential development

off Thieves Lane in Hertford for circa 280 units with Ben Yallop of Croudace Homes

2

I understand that you will be happy to see a draft of a TA in due course in advance of any application so that we can

discuss any issues and work together on this project.

With respect to the work we have done so far your colleague Dan will be reviewing the modeling but generally you

are content with the approach we have taken and the trip rate of circa 0.6 we have used rather than the lower one

observed at Turpins Close. You would like us to undertake a sensitivity test of assignment based on the 2011 Census

(work location) when this is available I( I believe soon) and compare this to the findings of our site observations.

We will of course issue all the modeling as part of our TA including the PM ARCADY tests for the A414 junction and

both AM and PM for the Welwyn Road junction.

We discussed the approach to access and agreed that this can all be solved in due course and that one or two access

points may be appropriate for the site but that it could operate with one access, in which case and emergency

access would be required. Access layouts should meet the MfS standards of visibility and consider the position of

existing junctions. You described HCC approach that they now adopt the main routes only and any short cul- de-sacs

generally are not adopted.

We discussed any traffic schemes or developments that we should consider as part of the assessment but you

confirmed that there were none in proximity which would impact upon our work.

We will of course include the relevant Local and National Policy within our document to ensure that we comply on

transport grounds and you suggested we review the Hertford and Ware Urban Transport Plan as well.

You discussed the HCC relationship with Croudace which is good and that you would require a planning obligation

for transport so that benefits can be made strategically.

I believe you asked that we review accident patterns at the A414 roundabout just to the west of the rail-bridge, we

will be reviewing accident patterns as part of our TA and so will extent to this junction as well.

This is all I can recall, so please add if there is anything else. Overall a positive meeting and I believe you confirmed

you would not have an objection on highway grounds as things currently stand.

I would be grateful if you would confirm this is a correct interpretation of our meeting as soon as possible and

please feel free to call with any questions/clarifications.

Kind Regards,

Patrick Eggenton EAS Unit 108 The Maltings Stanstead Abbotts Herts SG12 8HG t 01920 871777 m 07709 694819 www.eastp.co.uk

From: Patrick EggentonSent: 19 December 2012 16:52To: 'matthew.armstrong@hertfordshire.gov.uk'Subject: Proposed Development, Land at Thieves Lane HertfordAttachments: EXISTING A414 RB AM PEAK WITH DEV 121212.pdf; EXISTING A414 RB AM PEAK

121212.pdf; 1369 Hertfordshire.xlsm; Location and Facilities Plan pe Layout1 (1).pdf

Matthew,

As discussed just now, EAS has been appointed to prepare a Transport Assessment for a proposed development off

Thieves Lane at the west side of Hertford, (please see location plan attached). The development is likely to be

formed of 250 to 300 residential units and have two access points, one off Thieves Lane and one off Welwyn Road.

The detail of the access points has yet to be resolved but in principal there is space under the developers

control/Highway Land to implement priority junctions.

We have already undertaken some traffic assessment work to prove the viability of the development with mind to

the conditions of the A414 as it passes through Hertford. We decided it would be prudent to determine the peak

hour trip rate for existing residences off Thieves Lane and to this end we undertook a cordon count of Turpins Close

between 07.30 and 09.30 on a neutral weekday. At the same time we also completed a distribution survey to

determine vehicle assignment. We expected that there would be peak spreading from these developments in order

to avoid the worst periods of congestion on the A414 and also that the assignment would generally avoid the A414

into Hertford.

The results thoroughly concur with our expectations, the peak hour two way trip rate was 0.39 and only 12% of

traffic departing from the development in the peak period headed towards Hertford on the A414.

We have prepared a full Arcady for both the AM and PM peak hours for the A414/Hertingfordbury Road/Theives

Lane R/b and the Thieves Lane/Welwyn Road R/B.

Full classified turning data for the A414 R/B was recently collected on a neutral weekday together with a queue

length survey of all arms. Prior to this the junction was visited on three occasions in the AM peak specifically to

observe the traffic. In fact this junction works very well and queues are minimal. We have modeled the junction

using ARCADY and our ‘existing traffic’ ARCADY output (EXISTING A414 RB AM PEAK 121212.pdf) exactly replicates

the existing traffic conditions. We then added development traffic based on actual turning movements at this

junction rather than the observed assignment from the cordon survey and also using a 50% higher trip rate than the

that observed from the cordon survey for reasons of being robust. The results of the ‘existing’ and ‘with

development’ models are as follows;

As can be seen there is a negligible increase in RFC and Queues with the ‘with development’ over the existing

situation.

We have undertaken the same exercise for the Welwyn Road junction and this continues to operate well within

capacity and I have not attached the results here just to keep the size of this email down.

We spent some time considering how to model the A414 roundabout as it was clear that the flows into the

roundabout from Hertford are regularised by the signals upstream. Thus the flows onto the roundabout are

remarkably similar in each quarter of an hour period. We therefore built the model using the ‘Direct Input’ and

actual HGV options rather than the more simple OD TAB and default HGV option.

I have attached the results of the AM ARCADY Models and the classified traffic flow turning count data for your

perusal.

It is now my intention to comprehensively prepare the Transport Assessment document and so I would be grateful

for your views on the work we have so far completed and also an indication of any committed development in the

area which we should assess together with any committed highway improvement schemes.

If there are any specific matters that you would like to see addressed in the TA please let me know, I would like to

open up some regular dialogue with you as I am sure that new development in Hertford of this order will cause

some concern and I would not want it to come as a surprise for any parties involved.

Please confirm that you have received this email and please contact me should you have any questions, I look

forward to hearing from you shortly. Please note that we are based in Stanstead Abbotts so it would be very easy

for us to meet with you if that would help explain this further; it may equally be expedient for you to visit our offices

as we can the go through all the scheme data we have electronically.

I look forward to discussing this in more detail in the new year.
