A demonstration project aiming to develop a new system that uses traffic and air quality data modelling to predict traffic flow scenarios based on transport patterns, traffic management regimes, and emission profiles.
The Urban Traffic Management and Air Quality project (uTRAQ) is a demonstration project supported by the European Space Agency. Led by TRL, the project aims to develop a new system that uses traffic and air quality data modelling to predict traffic flow scenarios based on transport patterns, traffic management regimes, and emission profiles.
At a high level, uTRAQ is a collection of integrated software components that is used to enhance an existing UTC system - in this case SCOOT – in order to optimise traffic signal timings for both improved/maintained air quality and traffic flow, instead of just for optimal traffic flow.
Based on extensive end user requirements and stakeholder consultation, the system is being developed using a waterfall approach. Following consultation, comes system planning, system design and creation, system assembly and testing finally ending in system demonstration, all over the course of two years.
The paper will detail work plans and progress in achieving four objectives:
• The provision of city-wide data for traffic and air quality for the support of policy decisions at an operational level;
• The development of a new operational service in close participation with local authorities for managing their traffic and air quality through broad participation of local authorities, SMEs, and other industrial businesses;
• The utilisation of space assets: earth observation for air quality; meteorological data; GNSS-based floating car data, which will lead to better exploitation of such data for an integrated near real-time system; and
• To demonstrate a manual/automatic monitoring and decision support tool to aid traffic management tools at an operational level, considering a range of policy level objectives.
