1. STRATEGIC PRIORITY –........BUSES, TRAMS & FIRE +brh Presented by Ben Hallworth

2. +brh Focusing on the delivery of strategic priority in networks, …where a strategy can target identified elements of delay, The main priority tool used is ‘telents’ STM software… Presentation order STM Overview Supporting Tools Example 1 – Buses, Leeds Example 2 – Buses, Pudsey Bus Station Example 3 – Trams, Edinburgh Example 4 – Fire Priority Green Wave OVERVIEW

3. +brh ‘STM’ (Strategic Traffic Management) is a software product developed by ‘telent’ Originally developed by Leeds CC under the DfT sponsored UTMC01 project ….previously known as ‘SPRUCE’ Implemented in 5 authorities: Leeds, Sheffield, Calderdale, Bradford and Edinburgh. Priority implemented at over 400 junctions. Strategies are coded in a high level language and delivered via central UTC – (both Peek & Siemens UTC interfaces) what does it look like... STM

4. +brh Spreadsheet like software

5. +brh Isolated nodes Extensions / Recalls (on VA sites ‘extensions’ achieved using ‘holds’) Passing of central AVL to MOVA priority sites Groups of nodes Specific combinations of extensions & recalls Repeat priority stage Cycle time changing (e.g ‘doubling’) Offsets (with restoration) Offsets (cumulative) ‘Pick up & drop off’ from VA (then ‘extend’ or ‘recall’ – or ‘hold’ or ‘force’ etc. ) Linking of nearby VA junctions Advance stage demanding...commonly used STM strategies

8. +brh EXAMPLE 1 – Buses, Leeds 1 2 3 5 4 Buses targeted to reach here 1 cycle earlier Radial with 5 nodes & 2 bus stops Target inbound delay Outbound less of an issue

9. +brh buses take around 220s or 290sor even 360s

10. +brh EXAMPLE 1 - Strategy 1 2 3 6 Bus-gate green recalled green extended Green extended All timings offset 4

11. +brh each band is reduced by almost 50s

12. +brh each band is reduced by almost 50s Mean benefit 47s (AM peak) (Outbound benefit lower ~ 10s)

17. +brh Due to go live in summer 2014, Priority across the City Centre will be provided by STM, Aim is to provide a high level of priority with minimal disruption to traffic. Junction Tram Stop Princes Street..to Airport Line END Haymarket EXAMPLE 3 - EDINBURGH TRAMS

18. +brh Tram stops well-spaced – with typically 3-5 junctions between, Lower frequencies of trams gives longer time-horizons and greater priority. Junction Tram Stop Princes Street..to Airport Line END Haymarket EXAMPLE 3 – SUB NETWORKS

19. +brh Junction Tram Stop EXAMPLE 3 - SUB NETWORKS Optimal signal timings within a sub network can be well defined, The key to this is the ability to predict the arrival time of a tram at each sub-network.

26. +brh Based on research carried out in 2009 the West Yorkshire Fire Service commissioned a pilot ‘green wave’ priority system, which has recently been extended. EXAMPLE 4 - FIRE GREEN WAVE Fire Station Junction

27. +brh Original Pilot success criteria Ensure and increase safety levels for the public, Flush traffic from downstream junctions ahead of the Fire Appliance. Key differences to Buses/Trams Fire Appliances are extreme low-frequency vehicles; Stage skipping can be considered; Disruption to other traffic is acceptable Fire Appliances do not stop at bus/tram stops. Fire Appliances do not follow known routes. EXAMPLE 4 - FIRE GREEN WAVE

29. +brh Numerous AVL Triggers are used to constantly monitor the Appliance’s progress and to determine it’s route Fire Station

34. +brh Three STM strategic priority examples have been discussed with increasing priority needs; Bus Priority – targeting of particular delay issues with specific techniques can yield significant benefits. Tram Priority – a more gradual system designed to achieve minimal tram delay without excessive traffic disruption. Fire Appliance Priority – ultimate low frequency vehicles allow aggressive strategies to ensure green wave progression. SUMMARY END
