Abstract

Exhaust emissions in residential areas with different street network configurations L. Smidfelt Rosqvist Lund University, Department of Technology and Society, Sweden Abstract Difficulties in reducing travel demand have created an interest in using design to reduce vehicle mileage per trip as well as pollution rates. Traffic generated in residential areas accounts for approximately 25% of private urban vehicle mileage. The objective of this study was to investigate differences in fuel consumption and exhaust emissions for built-up residential areas in relation to differences in the design of street networks. The configuration of streets greatly influences driving behaviour, and thus also exhaust emissions and fuel consumption. This study examined five areas with three different configurations: a traditional grid network, and designs feeding the traffic in from a surrounding street or fiom a centrally located street. Differences in total fuel consumption and amount of exhaust emissions were anal
