The Denver Regional Transportation District (RTD) and ITS solutions provider Init have announced the launch of a centralised live traffic signal priority system project (LIVEtsp).
The first LIVEtsp in the USA will support up to 400 buses simultaneously and is designed to help speed up buses’ journey times.
Developed by Mattersoft, the LIVEtsp web-based user interface provides a real-time map showing vehicle positions once per second for real-time accuracy.
Ahead of its deployment, the system was configured at 22 of RTD’s key intersections throughout the Denver area.
RTD’s system supports up to 400 vehicles online simultaneously and manages approximately 3,000 traffic signal priority requests daily.
The system includes a conditional priority feature, whereby buses are prioritised according to their current lateness and/or load. Buses that are ahead of schedule will not be granted priority.
Priority requests will be processed on the server based on incoming vehicle data and transmitted to the city’s traffic signal controllers through a seamless cellular connection from the LIVEtsp backend.
The live traffic system will also offer comprehensive performance reports with insights into system performance and optimisation opportunities for users.
LIVEtsp at RTD adjusts traffic signals in real-time allowing their buses to spend less time at red lights resulting in shorter travel times and more efficient routes.
Eric Farrington, RTD senior project manager at Init, said: “RTD is excited about the new conditional TSP feature. It lets our buses skip priority requests when they’re ahead of schedule or empty, making our service smarter and more efficient.”
Due to its centralised nature, the system requires no additional vehicle hardware and only a small modem and basic relay in each traffic control cabinet.
Achievements and innovations in intelligent transport systems will be celebrated at the third annual CiTTi Awards, which will be held on 26 November 2024 at De Vere Grand Connaught Rooms in London. Nominations are open now! Please visit www.cittiawards.co.uk to learn more about this unmissable event for the UK’s transportation sector
