The application of traffic data in developing Chinese light duty driving test cycle

Abstract

Based on the research of the traffic flow model, generating the Vehicle Hours Travelled (VHT) and weight factors matrix of different cities in different speed phase by using 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 in different speed phase with chi-square test to select candidate short trips, and to determine the test cycle duration of each phase in developing Chinese Light Duty Driving Test Cycle.
