The Urban Traffic Management and Air Quality project (UTRAQ)

The Urban Traffic Management and Air Quality project (UTRAQ) is a European Space Agency supported demonstration project, under the ARTES IAP 20 (Advanced Research in Telecommunications Integrated Applications Programme 20). Led by TRL, the project is for the development a new system which uses traffic and air quality data modeling 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, to be able to optimise traffic signal timings for both improved / maintained air quality and traffic flow, instead of just for optimal traffic flow.
1.1. Project Approach
The approach used in the system architecture is based on modularity, with the different levels and types of functionality of UTRAQ coming from discrete software modules. The combination of a decision support tool with a library of strategies, state of the art traffic model, air quality model and UTC adaptor will enable near real time analysis of traffic and air quality which are then passed to the UTC.
Based on extensive (end) user requirements and stakeholder consultation, the system is being developed using a waterfall approach. Following consultation, comes system planned, system design and creation and then system assembly and testing which is followed by system demonstration, all over the course of two years.

1.2. Project Objectives

With the project culminating in the results from a number of live sites, which will be used to demonstrate the application, value and measured effectiveness of the UTRAQ system, the project is fully aligned with TRL Software in that much of our research leads to the development of innovative software solutions - Delivering Transport Science through Software.
The key project objectives are:
• Promotion of how space applications can be used for the management of traffic and air quality
• Provision of city-wide data for traffic and air quality for the support of Policy decisions at an operational level;
• Development of a new operational service in close participation with local authorities for managing their traffic and air quality through broad participation by key factors such as local authorities, SMEs, and other industrial businesses;
• Utilisation of space assets: earth observation for air quality, met data; GNSS based floating car data, leading to better exploitation of such space asset-based data for an integrated near real time Bringing together the disciplines of computational intelligence, air quality analysis and transport management to maximise the implementation and integration of such a 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.
