An innovative feature of this study is to firstly attempt to capture rear-end collision potentials from the analysis of inductive loop detector data. Signals collected from loops are applied for monitoring individual vehicle information on freeways to estimate safe stopping distances in car-following situations. An index to quantify the potential of rear-end collisions is derived, and further employed for developing criteria to evaluate levels of rear-end collision risks. The proposed methodology based on loop detector data enables to identify collision potentials in real time. It is believed that the index would be a valuable tool for operating agencies in developing various strategies and policies toward enhancements of traffic safety.
本研究的一个创新点是首次尝试通过分析感应线圈探测器数据来捕捉追尾碰撞可能性。从线圈收集的信号用于监测高速公路上的单车信息，以估计跟车情况下的安全停车距离。推导出一个量化追尾碰撞可能性的指标，并进一步用于制定评估追尾碰撞风险水平的标准。基于线圈探测器数据提出的方法能够实时识别碰撞可能性。据信，该指标将成为运营机构制定各种交通安全提升策略和政策的宝贵工具。
