Abstract
In order to solve the enormous difference about safe headway between the theoretical value from academic researches and the observational value from practical road conditions, this paper establishes a new vehicle-following model to accurately simulate the vehicle-following process. The model well simulates the actual situation, and provides an operable safety distance reference value for car drivers. Combined with the experiences of outstanding drivers, the model reengineers an integrated process as guidance including maintaining safe headway and changing traffic lane or braking. In addition, the paper discusses the limit of safe headway through sensitive analysis, and finds the reliable measures, so the safe headway could be shortened to improve the efficiency of road utilization. The broad applicability of the conclusion is verified by empirical data.
