The invention discloses a multi-mode traffic information acquisition unit length determination method based on traffic simulation. The method comprises the following steps: acquiring traffic facility information in a detection range of an entrance lane of a target intersection; determining a comprehensive evaluation index of the traffic information acquisition unit, wherein the comprehensive evaluation index comprises simulation accuracy and efficiency; determining a non-motor vehicle and pedestrian traffic information acquisition unit based on traffic simulation according to the separation condition of pedestrians and non-motor vehicles; and determining a motor vehicle traffic information acquisition unit based on traffic simulation. According to the method, a long detection range of the entrance lane of the intersection is divided into a series of small traffic information detection units according to different mixed driving proportions, compared with a large traffic information detection range, the traffic information obtained by the small detection units is more accurate, the real traffic state can be better reflected after the traffic information is input into simulation software, and an optimal division scheme is screened out in the acquisition unit division set, so that the purpose of optimally dividing the traffic information acquisition units is achieved.
本发明公开了一种基于交通仿真的多模式交通信息采集单元长度确定方法,方法包括:获取目标交叉口进口道检测范围内的交通设施信息;确定所述交通信息采集单元的综合评价指标,包括仿真的准确性和高效性;根据行人与非机动车的分离情况,确定基于交通仿真的非机动车与行人交通信息采集单元;确定其基于交通仿真的机动车交通信息采集单元;本发明按照将交叉口进口道一个长的检测范围依据混行比例不同划分为一系列小的交通信息检测单元,相比于较大的交通信息检测范围,小的检测单元获取的交通信息更加精确,输入仿真软件后更能反映真实的交通状态,在采集单元划分集中筛选出最优的划分方案,达到最优化划分交通信息采集单元的目的。
