2004 - China - Vehicle Classification for Expressway Capacity Analysis in China

A new vehicle classification is given in this paper for expressway capacity analysis in China, because the existing vehicle classification causes some problems, such as the vehicle-types whose sizes are the same have different performance characteristics. The new vehicle classification is principally based on free-flow speed together with the characteristics of vehicle configuration and wheelbase frequency. According to this principle, dynamic cluster is used to combine the existing vehicle-types into three new vehicle-types, which are labeled passenger car, heavy vehicle, and unidentified, respectively.
