The Application of Traffic Data in Developing Chinese Light Duty Driving Test Cycle

Abstract

Based on the research of traffic flow model, generating the Vehicle Hours Travelled (VHT) and weight factors of different cities and different speed range by using of the GIS whole road network data and traffic low-frequency dynamic data. Applying weighting factors to generate a unified speed—acceleration distribution of different cities and different speed range for subsequent chi-square to select candidate short trip, and to determine the test cycle duration in developing Chinese Light Duty Driving Test Cycle. 交
