1. INTRODUCTION

1.1 This report details the results of a road safety review on a section of the A1

Falloden Way/ Lyttelton Road, Hampstead Gardens in North West London

from east of the North Circular Road to Winnington Road, a street to the

west of the A1000. The section of route subject of this study is highlighted in

Figure 1 and is approximately 1.8km long.

[Background image taken from open source mapping]

1.2 The review comprised of a site visit on the 13th November 2018 which

involved driving, cycling and walking the route. The weather at the time of

the site visit was fine and dry. The review also includes an analysis of police

road traffic crash data. Data on the collision history has been taken from

“Crashmap” [www.crashmap.co.uk ].

http://www.crashmap.co.uk/


1.3 The following areas of road safety have been considered based around road

safety audit principals:

Visibility;

Layout of junctions;

Non-Motorised User (NMU) Provision [principally pedestrians and

cyclists];

Road Signs and carriageway markings.

Parking areas particularly laybys.

1.4 Drainage and lighting has not been assessed in detail as this is beyond the

scope of the study. On the day of the site visit many areas of the footway

were covered with leaves. This has not specifically been raised but is

considered to be a hazard and the route would benefit from inspection for

street cleansing.

1.5 For the purposes of this study the route has been broken down into 4 distinct

sections:

Section 1 covers west of the junction of Beaufort Drive to the east of

Brookland Rise junction near the entrance to Northway Gardens;

Section 2 covers west of Westholm to east of Eastholm;

Section 3 covers the eastern part of the route east of Greenhalgh Walk

to east of the junction with Winnington Rd.

Section 4 covers the route between the traffic signal junctions of

Northway and Kingsley Way.

1.6 A Diagrammatic layout of the A1 route is shown in Figure 2 highlighting the

different sections.

2. TRAFFIC FLOWS

2.1 The A1 forms part of the TfL strategic route network and carries over 36000

daily vehicle movements (2017 DfT traffic data, site reference 46076). A

breakdown of the different types of vehicles recorded is shown in Figure 3.

Motorcyclists and cyclists represent a very small proportion of overall traffic

using this route.

Figure 3: Percentage breakdown of vehicle type using the A1

2.2 TA 79/99 advises a 9.0 metre urban 30mph route has a possible capacity of

1550 vehicles per hour. The current flows along the western section of the

route, and from observations, indicate it is operating at capacity in peak

period.


3. DESCRIPTION OF ROUTE

3.1 The western section between Beaufort Drive and Northway is a single

carriageway. The eastern section of the route is a dual carriageway. The

western section, between a point east of Beaufort Drive and east of

Blandford Close is subject to a 30mph speed limit, with the remaining section

subject to a 40mph speed limit.

3.2 The route has the following features:

A central hatched area runs along the majority of the route with the

exception of a short length of the western end and at the traffic signals

which have a paved central reservation;

Traffic signals are installed at 2 crossroad junctions: Northway and

Kingsley Way;

Two pedestrian signalised crossings operate near the junctions with

Addison Way (toucan which includes cyclists) & Widecombe Way

(pelican);

There are 18 priority junctions with side roads, 11 on the north side and 7

on the south side (This includes the access by Heathfielde Medical

Centre). 5 of the junctions are defined by a right turn lane;

There are approximately 12 private access-ways which directly join the

route;

There are traffic islands at 13 locations with 9 of them incorporating

uncontrolled pedestrian crossing facilities.

There are 12 defined bus stops, 6 on the north side and 6 on the south

side. 8 of these bus stops are laybys.


3.3 The route is covered by red route parking controls. On-street parking is

permitted in 8 different areas:

Section on north side west of Westholm;

Section on north side between Westholm and Midholm;

Section on north side between Midholm and Eastholm;

Section on north side east of Eastholm;

Section south side west of Midholm;

Section north side between Hill Rise and Ossulton Way;

Section south side between Hill Rise and Ossulton Way;

Section north side east of Ossulton Way

All the parking bays are protected in laybys with marked spaces.

3.4 The geometric design of Major/Minor priority junctions is specified in DMRB

guidance TD 4295. The guidance indicates that “Traffic on the minor road

gives way to traffic on the major road and is normally controlled by "Give

Way" signs and road markings”. There are three basic types of layout:

Simple Junction [300 vehicle two-way AADT];

Ghost Island Junction [They are considered to be highly effective in

improving safety]

Single Lane Dualling [Generally only appropriate for roads with hard

shoulders];

The type of layout will depend on the flows. The current flows of over 30000

AADT on the A1 indicate a simple design is inappropriate and any access

should have a ghost island and central hatching. This is broadly achieved at

all the priority junctions on this section of the A1 route. However as traffic

flows are so high right turning traffic will inevitably need to make the

manoeuvre in two stages which is not ideal. Visibility at these junctions is

discussed under site observations in sections 5 to 8.


3.5 Fixed traffic enforcement cameras operate on this route. 3 of the cameras

operate just to the east of the study area - a red light at the signal junction

with ‘The Bishops Avenue’ and two speed cameras (east/westbound) by

Bancroft Avenue. The 2 cameras in the study area are east and westbound

speed cameras to the east of Gurney Drive junction.

3.6 In terms of the bus stop environment the following issues should be

considered as part of their design.

Security (including lighting)

Bus stop post and flag

Surface markings for buses

Bus passenger shelter and seating

Information (including timetables and maps)

Drainage

Pedestrian footway

Height and type of kerb

Adequacy of waiting area

Space for bus to straighten

Approach and exit paths for buses

Connectivity with footway

Convenience for passengers

Only specific road safety issues will be raised as part of this study under the

site observations set out in sections 5 to 8.


4. COLLISION HISTORY

4.1 Data on the collision history is available on line from “Crashmap”

[www.crashmap.co.uk ]. Details of serious and fatal collisions in the past 5

years are attached in Appendix 1. To provide an overview of collision history

the past 10 years of data between 2008-17 has also been summarised.

4.2 A collision is classed according to the most severe casualty involved, and

one collision may involve several casualties. The casualty severity definition

is summarised as follows:-

Fatal injury includes only those cases where death occurs in less than 30

days as a result of the accident. Fatal does not include death from natural

causes or suicide.

Examples of serious injury are: Fracture; internal injury; severe cuts;

crushing; burns (excluding friction burns); concussion; severe general

shock requiring hospital treatment; detention in hospital as an in-patient,

either immediately or later; injuries to casualties who die 30 or more days

after the accident from injuries sustained in that accident.

Examples of slight injury are: Sprains, not necessarily requiring medical

treatment; neck whiplash injury; bruises; slight cuts; slight shock requiring

roadside attention. Persons who are merely shaken and who have no

other injury are generally not included unless they receive or appear to

need medical treatment.

4.3 A breakdown of the number of collisions for this section of route for the past

10 years is shown in Figure 4. Overall there have been 98 collisions

involving personal injury recorded by the Police between 2008-17. The

severity of the collisions is also indicated. There have been 3 fatal and 14

serious collisions (17 (KSI) killed or serious injured). 2017 witnessed the

highest number of recorded collisions but also the worst in severity involving

5 KSI.

http://www.crashmap.co.uk/

collisions per year between 2008-17

4.4 Collision numbers for each of the defined sections is also summarised in

Figures 5 to 8. The section with the majority of collisions is in section 4

between and including the traffic signal junctions of Northway and Kingsley

Way. All the 2017 KSI (5no.) was recorded within this section.

[Section 3] – Numbers of collisions per year between 2008-17


Figure 8: A1 between the traffic signal junctions of Northway and Kingsley Way

[Section 4] – Numbers of collisions per year between 2008-17

4.5 In the past 5 years of data (2013-17) the numbers of vulnerable road users

(pedestrians, cyclists and motorcyclists) being involved were recorded as

follows:

3 no Pedestrians (2 no KSI);

2 no cyclists;

13 no motorcyclists (1 no Fatal).

The incidents involving motorcyclists and cyclists represents a significant

number given these vehicles are only a small proportion of overall traffic flow

(see section 2.1).


5. SECTION 1

5.1 This section comprises of 3 priority junctions (Beaufort Drive, Addison Way

and Brookland Rise), 4 bus stops and a toucan signalised crossing between

Addison Way and Brookland Rise. A cycle track runs west of Addison Way

junction on both sides of the road (see Figure 9). This forms part of a local

cycle route no 54 which is signposted on Oakwood Road which runs south

and parallel to the A1 route. It re-joins the A1 at the traffic signal junction with

Northway (see report section 8). The location of collisions and issues raised

are indicated in Figure 10.

http://www.london.cyclestreets.net/


5.2 Issue observed: High traffic flows create difficulties for turning right out of

side roads.

Detail: The traffic flows on this section are very high and turning right out of

the side roads was observed as challenging. The collision rate for turning

traffic, particularly impacts on collisions involving motorcyclists, and is

unsurprising given this difficulty. There are limited options to address this

collision rate and therefore some improvements should be given to improve

the surfacing on the approach to the junctions. The use of High Friction

Surfacing (HFS) in general has a positive impact on road safety as it helps

vehicles brake and stop early, particularly in front of turning vehicles.

RECOMMENDATION: Investigate the provision (or reinstatement) of High

Friction Surfacing on the approaches to the junctions of Beaufort Drive,

Addison Way and Brookland Rise.

5.3 Issue observed: Trip hazard near bus stop east of Addison Way.

Detail: A trip hazard for pedestrians was observed in the footway area at the

existing bus stop east of Addison Way. This is shown in photo 5.

RECOMMENDATION: Reconstruct the bus shelter and footway here to

eliminate the trip hazard and also widen the footway here to facilitate

wheelchair and pushchair access.

5.4 Issue observed: End of cycle route is unclear.

Detail: The end of the cycle route at Brookland Rise and Addison Way is

unclear which may encourage cyclists to continue riding on the footway

away from these junctions. This lack of clarity may introduce pedestrian/

cyclist conflict on the footway.

RECOMMENDATION: Review the cycle track and route signing at Brookland

Rise and Addison Way Junctions to make it clear the best route for cyclists.

6. SECTION 2

6.1 This section comprises of 3 priority junctions (Westholm, Midholm and

Eastholm), 4 bus stops and four on-street parking laybys. Residential

properties front this section. The location of collisions and issues raised are

indicated in Figure 11.

6.2 Issue observed: Poor visibility from Westholm and Midholm junctions.

Detail: The visibility on the approach to Westholm and Midholm junctions is

poor (See photos 6-9). The indications are this has influenced the number of

collisions at Westholm junction (3 in 5 years). Young drivers appear to

struggle with this junction. This is a cul-de-sac and there is no other point of

access unlike Midholm that can use Hill Top and Hill Rise. Visibility at

Eastholm is satisfactory.

RECOMMENDATION: Either remove the trees on the corner (which may be

a controversial issue) OR construct a new traffic island in the central

hatching on the eastbound approach to Westholm housing a speed activated

‘side road ahead’ warning sign.

6.3 Issue observed: Effective footway width reduced by overgrown hedging.

Detail: The effective width of the existing footway on the north side is

reduced due to overgrown hedging (See photo 11). This is becoming a

hazard in places and needs to be addressed before it forces pedestrians into

the carriageway

RECOMMENDATION: Liaise with Highway Authority/ Frontages to cut back

hedging to maintain effective footway width.

7. SECTION 3

7.1 This section comprises of 5 priority junctions on the north side (Blandford

Close, Gurney Drive, Cornwood Close, Widecombe Way and Vivian Way)

and 4 priority junctions on the south side (Winnington Road, Norrice Lea, two

accessways onto Deacons Rise). Visibility on the approaches to the

junctions is satisfactory. There are 3 bus stops within this section in laybys.

Residential properties front this section. The location of collisions is indicated

in Figure 12 and no serious (KSI) incidents.

7.2 Although no specific issues were observed, this section does have a number

of incidents involving ‘young drivers’ and motorcyclists. These are however

spread along the route which makes engineering solutions unlikely to be

effective. Speed enforcement cameras already operate here which probably

is behind the low KSI rate.

8. SECTION 4

8.1 This section comprises of 2 signal junctions and 2 priority junctions

(Greenhalgh Walk and the service road adjacent to the Medical Centre), two

bus stops and three on-street parking laybys. The frontage is a mixture of

retail, commercial and residential properties. There is a medical centre on

the south side east of Kingsley Way. A local cycle route crosses north-south

at Northway and Hill Rise traffic signals (see Figure 13). The location of

collisions and issues raised are indicated in Figure 14.

8.2 Issue observed: Poor pedestrian crossing facilities at Kingsley Way Signal

Junction.

Detail: The traffic signal junction at Kingsley Way/ Ossulton Way has been

the subject of a traffic survey and for completeness this is attached in

Appendix 2. The existing junction has a pedestrian signal phase on the west

side of the junction. All the remaining arms have no signal phase crossing

the junction, particularly the east side of the junction. An elderly pedestrian

was observed being escorted across the A1 could not cross within the gaps

created and would not have completed the manoeuvre without a van driver

showing consideration to wait for them to cross. In addition pedestrians were

observed crossing the central reservation by Greenhalgh Walk to get to the

Medical Centre. The collision history involving pedestrians (1 Fatal & 1

Slight) supports the need to review the pedestrian crossing facilities at this

junction.

RECOMMENDATION: Investigate closing the existing uncontrolled crossing

point on the east side of the junction and provide a new staggered signalised

crossing on the east side of the junction. The impact on traffic flows is

understood. The eastbound pedestrian stage can operate as a separate

phase in the same manner and mirror the westbound phase. This is currently

employed at ‘The Bishops Avenue’ signal junction just to the east of this

study area. Countdown signals should also be deployed in the same way as

at ‘The Bishops Avenue’ signals. Phasing across the north and southern

arms should also be investigated and also installed if feasible. See Figure

15.

8.3 Issue observed: Uneven paving in footway in Hill Rise .

Detail: Sections of existing footway are damaged in Hill Rise. This creates a

trip hazard for pedestrians. This is shown in photo 14.

RECOMMENDATION: Inspect and reconstruct the footway area to remove

the trip hazard.

8.4 Issue observed: The paving surrounding the existing trees on the south side

9. SUMMARY

9.1 This report details the results of a road safety review on a 1.8 km section of

the A1 Falloden Way/ Lyttelton Road, Hampstead Gardens in North West

London from east of the North Circular Road to Winnington Road, a street to

the west of the A1000. Overall there have been 98 collisions involving

personal injury recorded by the Police between 2008-17. There have been 3

fatal and 14 serious collisions (17 (KSI) killed or serious injured). 2017

witnessed the highest number of recorded collisions but also the worst in

severity involving 5 KSI.

9.2 For the purposes of this study the route has been broken down into 4 distinct

sections:

Section 1 covers west of the junction of Beaufort Drive to the east of

Brookland Rise junction near the entrance to Northway Gardens;

Section 2 covers west of Westholm to east of Eastholm;

Section 3 covers the eastern part of the route east of Greenhalgh Walk to

east of the junction with Winnington Rd.

Section 4 covers the route between the traffic signal junctions of

Northway and Kingsley Way.

9.3 The review incorporated a site visit which considered the current road safety

collision record but also considered standards for the following criteria:

Visibility;

Layout of junctions;

Non-Motorised User (NMU) Provision [principally pedestrians and

cyclists];

Road Signs and carriageway markings;

Parking areas particularly laybys.

A number of issues have been observed together with a range of

recommendations for sections 1, 2 and 4.


9.4 The issues observed and the recommendations for route section 1 are

described in detail in Section 5.0 and summarised as follows:

High traffic flows create difficulties for turning right out of the junctions of

Beaufort Drive, Addison Way and Brookland Rise. The provision (or

reinstatement) of High Friction Surfacing on the approaches to these

junctions should be investigated.

A trip hazard for pedestrians was observed in the footway area near bus

stop east of Addison Way. The reconstruction of the bus shelter and

footway area should be investigated to eliminate the trip hazard but also

widen the footway to facilitate wheelchair and pushchair access.

The end of the cycle route at Brookland Rise and Addison Way is unclear

which may encourage cyclists to continue riding on the footway and

introduce pedestrian/ cyclist conflict on the footway. Review the cycle

track and route signing at Brookland Rise and Addison Way Junctions to

make it clear the best route for cyclists.



The visibility on the approach to Westholm junction is poor and is an

influence in the number of collisions (3 in 5 years). Either remove the

trees on the corner (which may be a controversial issue) OR construct a

new traffic island in the central hatching on the eastbound approach to

Westholm housing a speed activated ‘side road ahead’ warning sign.

The effective width of the existing footway on the north side is reduced in

places due to overgrown hedging which has become a hazard. There is a

need to liaise with the Highway Authority/ Frontages to cut back hedging

to maintain effective footway width.




There is an area of uneven paving observed in Hill Rise. The footway

should be inspected and reconstructed to remove the trip hazard.

The paving surrounding the existing trees on the south side to the east of

Northway is being pushed up by the existing tree trunk and the footway

should be inspected and reconstructed to remove the trip hazard.

9.7 One of the main issues observed is the poor pedestrian crossing facilities at

Kingsley Way Signal Junction outlined in Section 8.2. The existing junction

has a pedestrian signal phase on the west side of the junction. All the

remaining arms have no signal phase crossing the junction, particularly the

east side of the junction. The collision history involving pedestrians (1 Fatal

& 1 Slight) supports the need to review the pedestrian crossing facilities at

this junction. Suggested changes to this junction are described and shown in

Figure 15 and mirror similar staging as at the ‘A1/ The Bishops Avenue’

signals east of this route.

Summary Note A1 Falloden Way / Ossulton Way

Transport for London has commissioned a number of detailed surveys at this location.

Speeds

Speed surveys (Appendix A) were carried out over 7 consecutive days in 3 locations, between Midholm and Gurney Drive. The average speed recorded at all 3 locations was 28.7mph. The 85th%ile speeds between Hill Rise and Ossulton Way did not exceed 34.1mph. The national set enforcement thresholds for speed enforcement are set at Speed Limit + 10% + 2mph, so for a 30mph limit, that is 30 + 3 + 2, so 35mph. As the 85%ile here is not above the 35 NPCC guideline or 40mph “threshold” police would generally not enforce.

Right Turners

It was assumed that traffic was tailing back along Falloden Way thus extending past the existing right turn pocket which was in turn blocking the ahead movement of traffic. Following a 3 day survey (Appendix B), quantifying right turns from Falloden way to Kingsley Way the hourly average did not exceed 23 vehicles. Not one incident was recorded where right turners were blocking ahead flowing traffic.

Ped Surveys

Pedestrian crossing counts and Wait times (Appendix C) Pedestrians were not waiting an excessive amount of time at any of the crossings, all waiting times were under 30seconds. This shows that the facilities are good for pedestrians particularly considering they are crossing a major road

Appendix

Please refer to appendix A, B and C for further clarification.
