TSS in Urban Traffic Management and Air Quality project, UK
Is air quality a traffic management issue? The new uTRAQ (Urban Traffic Management and Air Quality) project uses satellite-generated atmospheric data to help local authorities devise traffic management strategies for reducing pollution levels and hotspots. The project is part funded by the European Space Agency and led by transport consultancy Transport Research Laboratory (TRL) in collaboration with TSS and the University of Leicester.
The software breaks new ground by bringing air quality, weather monitoring systems capability, modelling and traffic forecasting tools and adaptive management systems into one single, user-centric intelligent integrated solution. An intelligent decision support tool enables a traffic control operator to implement traffic control strategies which can be used to mitigate the effects of local traffic air pollution, reduce pollution hotspots and exceed air quality thresholds.
TSS’s role will be to implement and calibrate an Aimsun model of three test areas in the East Midlands in the UK using data provided by the local authorities. The Aimsun model will interact with an Air Quality Model (AQM) provided by the University of Leicester and with real-time SCOOT (and other) data to allow UTC strategies to be tested in real time, with the objective of finding strategies that minimise emissions.
uTRAQ is a modular system which works in conjunction with existing UTC systems such as SCOOT or TRANSYT Online. It is used to assess traffic control and air quality management strategies as part of the optimisation of traffic signal timings.
Eliminating the need for additional ground based sensors and infrastructure, the uTRAQ system takes data feeds from a combination of existing terrestrial and Earth observation space assets; information and data feeds such as:
- Current network state
- Air Quality
- MACC – Nowcasts and Forecasts
- Meteorological – Nowcasts and Forecasts
- The combination of a decision support tool with a library of strategies, state of the art traffic model, air quality model and UTC adaptor enables near real-time analysis of traffic and air quality. This is then passed to the UTC through the UTC Common Database.
uTRAQ presents a cost-effective tool in delivering an effective and coordinated approach to the reduction of Nitrogen Dioxide levels within UK cities.
