Refinement of Urban Vehicle Emission Inventories, Using Instrumented Electric Vehicles

摘要

This paper discusses the discrepancies between vehicle emissions calculated from conventional analysis and those derived by considering actual road speed data. Conventional methods use the average speed to ascertain vehicle emissions. This paper describes the use of an instrumented electric vehicle to acquire instantaneous speed and energy consumption data to derive emissions. A comparison of the two methods demonstrates that conventional analysis misrepresents vehicle emissions for congested roads.
