Abstract

The road pollutant emissions, above all in urban context, are correlated to many infrastructural parameters and to traffi c intensity and typology. The research work on road junction geometry, carried out in European research centres, has recently allowed to design new road intersection types which are of undoubted interest, especially in terms of traffi c functionality and safety, like the fl ower roundabouts (in which right-turn manoeuvres do not confl ict with the circulating fl ow). The main objective of this paper is to propose a model for the estimation the capacity, delay, levels of service and the pollutant emissions into fl ower roundabouts. A comparative analysis between conventional roundabout and fl ower roundabout has been carried out in terms of CO, CO2, CH4, NO, PM2,5 and PM10 vehicular emissions, evaluated by mean of COPERT Software which is developed as a European tool for the calculation of emissions from the road transport sector.
