Abstract

A visual heavy-duty vehicle (HDV) classification scheme is developed for use in collecting onroad field data and for use in allocating observed vehicle volumes to applicable MOBILE6 vehicle classes. The X-scheme employs only three HDV classes based upon the number of axles and growth vehicle weight ratings, which represents a hybrid scheme between the FHWA HDV classification scheme. A hybrid HDV scheme such as the X-scheme is needed not only for easy vehicle observation, but also for highway performance monitoring systems (HPMS) database development. The emission rate differences with the EPA guidance and the X-scheme methods for four pollutants are also presented.
