摘要/Abstract

摘要： 为了便于计算无信号平面交叉口机动车不同种类冲突点的个数，采用虚拟车道和象限表示平面交叉口.针对无信号平面交叉口中的T型交叉口和十字型交叉口，基于交叉口虚拟车道和交叉口象限，以及虚拟车道的转换方法，分别开发了相应的机动车不同种类冲突点数的计算模型，并进行了实际验证.验证结果表明，通过这些计算模型可以迅速地计算无信号T型交叉口和十字型交叉口机动车不同种类冲突点的个数，提高了工作效率，为交叉口交通安全评价和交叉口交通安全改善提供了便利工具.

Abstract: To conveniently calculate the number of conflict points of different type for motorized vehicles, intersection virtual lanes and intersection quadrants were used to represent a road intersection. For T intersections and cross intersections, based on the virtual lanes and quadrants and conversion method of virtual lanes, the corresponding calculation models of conflict points of different types for motorized vehicles were developed individually. The calculation models were validated. The validation results show that the calculation models can quickly compute the number of conflict points of different types for motorized vehicles at T intersections and cross intersections, which enhances the work efficiency and provides advantages for traffic safety evaluation and safety improvement of intersections.

Key words: unsignalized intersections, calculation models, traffic conflict points, motorized vehicles
