The SPARC (Système de Pilotage de l’Air et des Routes par véhicules Connectés—Management System of Air and Road through Connected vehicles) project aims to provide road managers with a better understanding of the impact of their infrastructures on air quality. Traditionally, road managers focus essentially on traffic fluidity and traffic safety as main indicators to define road infrastructure choices and policies. The project focused on developing a web platform that provides the road managers with additional indicators, mainly Air Quality Impact, computed directly from the real-time automotive traffic using floating car data. The SPARC project brings together in a single platform real-time floating car data provided by Autoroutes Traffic, road traffic emission modelling by IFPEN and air quality modelling by AmpliSIM. The project is funded by the ADEME Agency (French Agency for Energy and the Environment). After introducing the SPARC project, road traffic emission modelling using IFPEN state of the art motorization modelling and real-time automotive traffic data provided by Autoroutes Trafic is described. Then air quality modelling is presented for two setups in the Lyon urban area in France, including a densely urbanized area in the city center and a high traffic area along the ring road (Lyon périphérique). Results are evaluated against sensor data and discussed, particularly against traditional approaches that rely on statistical data to model traffic influence. Conclusion are then proposed particularly in the framework of operational monitoring of air quality at high resolution in urban areas.
