Impact Analysis of Driver’s Perception-Reaction Time on Performance of Crash Surrogate Indicators for Motorway Traffic

Due to the enormous losses to society, researchers have been seeking capable solutions to improve traffic safety for decades. As an alternative to the traditional crash data models, the crash surrogate indicators are proposed and applied to evaluate the traffic safety in various situations. The driver’s perception-reaction time (PRT), which is an important parameter in traffic safety and infrastructure design, has not been taken into account by several widely used surrogate indicators. In this regard, this paper aims to examine whether or not the performances of surrogate indicators can be improved by incorporating the impact of the PRT. In this study, the authors firstly modify surrogate indicators by involving the PRT into the crash mechanism. The crash and trajectory data collected on the Pacific Motorway are used to validate the modified surrogate indicators. The results show that the modified surrogate indicators outperform the existing ones.
