Abstract This report, presents a comparison of three methods of computing vehicle miles traveled (VMT) breakdown by vehicle class for urban areas. The report describes the three approaches--Nationwide Urban, National Emissions Data System (NEDS), and Localized--and presents results based on each. The analysis revealed that the NEDS approach tends to overestimate the Heavy-duty diesel vehicle (HDDV) fraction of VMT in urban areas. Local data were available for only a limited number of cities being modelled and, in some, the same problems that existed with the NEDS methodology were uncovered. The average of the available local VMT breakdowns that appeared accurate was very close to that obtained using the Nationwide Urban approach. Therefore, the report concludes that the Nationwide Urban approach should be used to compute the urban VMT breakdown needed for urban emission projections.
