Introduction1. Overview and benefits of modern Traffic

Management System concepts – although I'm light on quantified benefits today (save it for later)

2. Outline some constraints of existing traffic planning systems

3. Highlight opportunities to prioritise and prepare for:– Take up of modern Traffic Management Systems– Utilisation of increased future network capacity

Rail Traffic ManagementSystem Overview


Traffic Management Systems

Todays discussion is generic in the context of complex suburban railways operating mixed traffic with diverse fleets – this is not a case study of any specific example.

The needs of Railways have always been evolving and will continue to do so….


Evolution of Needs

Watch Pull Push Click Uh Oh!


What is a TMS?

A railway Traffic Management System is both a concept and grouping of functions, facilitating operation of a railway and enabling a service.

Its definitely not ‘plug n plug’, its certainly not COTS!

It is a Sub-System of a Rail System.


What is a TMS?

IEC 62290 - General Operational Hierarchy

Common concepts. Unique applications.

TMS

Standards and TMS• TMS (also known as ATS) is outlined in IEEE -

1474.1-2004 (CBTC Standard), but isn't ratified.• The equivalent IEC standard is 62290-2:2014

Railway applications – Urban guided transport management and command/control systems – Part 2: Functional requirements specification

• There are no EN or AU standards for TMS• Some Operators have standards but often refer to

just Control Systems – i.e. how to control an interlocking

• RSSB has no standards or specific requirements


TMS Functions

Big Players• Bombardier• Thales• Siemens• Alstom• Hitachi / Ansaldo• GE Transport

Plus the smaller ones• Cactus• Indra• Many others….

Significant Reference TMS Projects

• Network Rail ROC and Signal Box Consolidation Program: harmonisation of traffic management functions and systems across the country, including signal box modernisation and consolidation.

• Denmark Fjernbane Infrastructure East/West Signalling Program: replacement of top-‐to-‐bottom TMS and all interfacing sub-‐systems – two supplier strategy, east and west.

• RSSB UK -‐ Future Traffic Regulation Optimisation (FuTRO) Research Project: aims to identify technologies to support a vision of the rail industry in 2040.


Known Constraints in Existing Railways

Commercial in confidence

Constraints

There are many but lets roll through a few:

1. Timetabling2. Conflict Detection3. Fringing


Timetabling

Use Capacity EfficientlyIncrease Reliable Frequency of ServiceIncrease On time RunningMaximum System AvailabilityMore Flexible Last Minute Planning

Reduce Scheduled Live MaintenanceReduce Scheduled Possessions/OccupationsReduce Customer Delay Minutes


Timetabling

Timetabling with highly tuned signalling systems:Example of reliable timetabling needs:

• Non-ATO @ 20tphpd– Theoretical hw 144s– Operational hw 180s

• ATO @ 24tphpd– Theoretical hw 120s– Operational hw 150s

• Accurate network definition

• Minimal truncation • Risk and Recovery Margin

consistent and defined• Accurate Nodal Geo


Timetabling

Other Notable Constraints• Data definition of a rail networks can come from

multiple sources at different resolutions & accuracy.

• Cost of re-work for timetables with better validation prior to go-live.

• Freight paths on mixed traffic lines with higher capacities (e.g. 24tph):– Less Slots with more accountability


Conflict Detection

• ‘Mantronic’ methods for managing railways are coming off the page, out of people heads and into TMS.

• Huge culture change.• More data is available than ever to

help manage and regulate the network!

Conflict Detection and Resolution

Items worth considering:

Sydney Trains Example: ATRICS and New TMS

2. Mixing Headway & Scheduled Regulation Operating Methods on one network.

1. Network vs. Line/Area Conflict Detection – don’t duplicate functions particularly during migration.


Conflict Detection and Resolution

3. Impacts of Fleet and Crew Management.4. Interfaces with Incident Management and Detection Systems.5. Interfaces with Ticketing and Customer Information Systems.6. Poor Conflict Resolution =

Unreliable Timetable ExecutionPoor Automatic Train RegulationIncrease Operator Workloads


Example: Conflict Detection and Resolution


Fringing and Train Locations

• Converging wayside and onboard systems introduce constraints on how/where/when rollingstock can perform on a network.

• Timetables will need to be armed with more information about trips and allocated trains types.

• Both TMS/CS responsible for fringing need better prediction.

Opportunities


Value of Good Integration

Avoid project overlap, divert funds and resources where it is needed.

But make sure they integrate and contribute to a ‘plan’


Better Customer Outcomes: Intermodal Operations


• The paradigm of transport management is converging as technology simplifies how its controlled and regulated.

• Eventual Automation of other transport modes will concentrate traffic regulation methods and execution > including buildings!

• Railway TMS will need to better integrate with regulation methods of other transport modes > further work is required on concepts and requirements.

Intermodal Operations


Set Headcount Targets and Hit Them

• Operating and Maintenance Concepts supporting migration and staging of TMS deployment are critical.

• Be Bold with planning and Targets, but realistic.

• Workload and Human Factors are always issues.

• Put the onus on suppliers to achieve targets when specifying performance.


Asset Management Justification

• CPU based Signalling, Train Describers and Control Systems deployed in the late 80’s and 90’s are starting to hit the sweet spot for renewal or replacement justification.

• Older legacy system replacement supplement with another order of magnitude.

Wrap Up


Wrap Up

• TMS is not a new concept, but is still evolving.

• Don’t rely on Standards – it is not ETCS.• Significant projects in motion help wear a

large portion of cost and development of modern TMS.


Wrap Up

• Adopt not adapt policy, the Aus market cant carry innovation based on its contribution. (est <1%)

• Adopt isn’t just software, it also means considering how to minimise people and process changes, e.g.– Safe Working Processes– Operating Business Frame Work– Network Performance Metrics


Wrap Up

• Engineering a Timetable will influence the success of operating with TMS and network reliability.

• Conflict Detection and Resolution are worth investing in, but need time and effort to get it right.

• Fringing will become more complicated, systems and operators need to adapt.


And….

Asses the needs and stick to a plan > review, update and absorb innovation when it presents itself.
