The invention relates to the technical field of rescue warning, in particular to an emergency road decision-making method based on people flow perception. The emergency road decision-making method based on people flow perception comprises the following steps: collecting current road information and constructing road network data according to the road information; and obtaining the crowd density on the road network road. And calculating the pedestrian evacuation speed according to the road network data and the crowd density. And the evacuation time period is calculated through the pedestrian evacuation speed. And acquiring an evacuation path reaching the terminal point, and calculating the evacuation time of each evacuation path. And taking the evacuation path corresponding to the minimum evacuation time as the emergency evacuation path of the pedestrians. The evacuation path calculated by the method is based on the evacuation time, and the fastest evacuation can be carried out. The method is a dynamic pedestrian emergency evacuation path, and the evacuation efficiency of planning is higher. Pedestrians can be effectively diverted and evacuated according to real-time road network data, the road crowd density is reduced, and the evacuation efficiency is improved.
本发明涉及救援警示技术领域,具体的是一种基于人流量感知的应急道路决策方法。所述的基于人流量感知的应急道路决策方法包括如下步骤:收集当前道路信息并根据道路信息构建路网数据。获得路网道路上的人群密度。根据路网数据和人群密度计算获得行人疏散速度。通过行人疏散速度计算获得疏散时间段。获得到达终点的疏散路径,并计算各个疏散路径的疏散时间。将最小疏散时间对应的疏散路径作为行人的应急疏散路径。通过此方法计算的疏散路径以疏散时间为基础,可以最快的进行疏散。本方法为动态行人应急疏散路径,规划的疏散效率更高。能根据实时路网数据有效分流疏散行人,降低道路人群密度,提高疏散效率。
