The UK’s very first real-time transport model for live traffic management launched in the City of York, using PTV software, allowing traffic managers to ‘see’ congestion levels in areas without sensors or cameras.
Historically, the City of York Council (CYC) managed the transport network live through staff monitoring CCTV and social media feeds, with Network Monitoring Operators (NMOs) and transport engineers putting Manually implement new plans and signal changes to alleviate network issues. With PTV Optima installed in the control room, NMOs are now taking a more proactive approach to monitoring and influencing the network.

The York Optima real-time model is a live prediction of traffic conditions across the city. It combines dynamic offline transport models with live traffic data to provide the control room with a network-wide forecast of current and future congestion.
The model is integrated with over 100 live traffic flow sensors, over 100 live signal controllers, live speed data over the network provided by TomTom, and up-to-date information on road works and other changes to the road. network.
The living model combines all this data into a single view and a single ground truth. The control room uses this information to see in detail what is happening across the network, and not just in places with sensors or CCTV.
Optima also allows the control room to test alternative scenarios for the next hour, next day or weeks to come. The city therefore has an operational road modeling asset to monitor current conditions, plan for the near future, observe how plans unfold and use this knowledge to improve future strategies.
“We are delighted to be the first city in the UK to introduce this innovative and cutting edge technology to improve travel and pollution in York,” says Dave atkinson, responsible for programs and smart place at York City Council, explained: “Over the past 12 months, we have worked closely with consulting firm Wood Group and PTV to deliver the traffic model in real time Optima. At this early stage, it is already a success. We are able to predict future traffic levels based on our traffic behavior in real time and better manage traffic flow during peak periods by adjusting traffic lights according to traffic conditions.
“Working with York City Council and the other project partners has been a privilege,” says PTV UK’s technical director. Michel Olivier. “I have seen for myself how the fusion of transportation planning, traffic engineering and real-time data can provide an impressive traffic management solution.”
The York project is a component of the City of York’s Smarter Travel Evolution – STEP program, which is funded by the UK government. The project team was led by the City of York Council, consulting firm Wood Group and was carried out in partnership with PTV Group and independent strategic modeling experts RelativeGAP.
