旅游景区游客拥堵疏散路径规划仿真

Simulation of Congestion Evacuation Path Planning for Tourist Attractions

对旅游景区游客的拥堵疏散路径的规划,能够有效提高旅游景区游览效率。对拥堵疏散路径的规划,需要规划拥堵客流疏散需求,获取最短客流疏散时间角度,完成游客疏散路径的规划。传统方法获得各个疏散路径的初始阻抗,并通过定义惩罚函数来修正路径阻抗,但忽略了对客流疏散时间角度的求取,导致路径规划精度偏低。提出疏散路径规划模型。考虑了各个疏散路段的交通饱和量,采用多路径分配法将疏散路径需求分配至疏散路网上,规划拥堵区域的剩余客流疏散需求,从最短客流疏散时间的角度将疏散节点和路径上的需求整合在最优疏散路径的选取模型中。实验证明,上述模型减少了游客疏散时间以及滞留人数。

Traditional path planning methods ignore the angle of passenger flow evacuation time, which leads to the low accuracy of path planning. This paper puts forward evacuation path planning model. With considering the traffic saturation in each evacuation road, we use multi - path assignment method to assign the demand of evacuation path to evacuation road network, and plan the evacuation demand of residual passenger flow in congested area. From the shortest evacuation time of passengers, we integrate the demand of evacuation nodes and paths on the selection model of optimal evacuation path. Simulations prove that the above model reduces the evacuation time and the num- ber of stranded passengers.
