The invention relates to an expressway driving risk discrimination method based on a speed risk potential field. The expressway driving risk discrimination method comprises the following steps: 1) data acquisition and processing: acquiring and processing portal gate road section monitoring data, expressway accident data and map POI data; 2) analyzing the data acquired and processed in the step 1) to obtain speed data and traffic accident data; and 3) according to a data analysis result in the step 2), establishing a speed risk potential field model, and determining speed potential energy Vi, j, speed potential energy field intensity and speed risk potential field intensity to realize expressway driving risk discrimination based on the speed risk potential field. The problem that risk classification is difficult to realize in current driving risk discrimination in a macroscopic level can be solved.
本发明涉及一种基于速度风险势场的高速公路行车风险甄别方法,其包括以下步骤:1)、数据采集与处理:采集并处理门架卡口道路断面监测数据、高速公路事故数据和地图POI数据;2)、对步骤1)中采集与处理的数据进行分析,以获得速度数据和交通事故数据;3)、根据步骤2)中的数据分析结果,建立速度风险势场模型,确定速度势能Vi,j、速度势能场场强和速度风险势场强度实现基于速度风险势场的高速公路行车风险甄别。其能解决当下行车风险甄别在宏观层面较难实现风险分类的问题。
