Evaluation of the Impact of Freeway Pavement State on Traffic Safety
摘要
Abstract
The pavement surface condition index and skidding resistant index were selected as the characterization indicators of pavement state while speed standard deviation coefficient was taken as traffic flow characterization indirect indicators to reflect the state of the traffic safety.Considering the impact of traffic volume, the changing course of speed standard deviation coefficient of traffic flow along the actual sections was simulated.Meanwhile, combined with the existing road testing data, an evaluation model of the pavement state’s impact on traffic safety was established. Furthermore, the evaluation classification standard was put forward.An evaluation software was developed based on the proposed modle. Shanghai-Nanjing freeway was taken as a case for analysis.The results show that the proposed relation model can be used to evaluate the impact of pavement state on traffic safety accurately.关键词
