针对预约出行效益,开发了基于SUMO的城市道路预约出行仿真平台。该平台以真实出行需求作为非预约车流输入,利用基于A*算法的实时路径规划算法为预约车辆规划路径,实现预约机制下的真实路网交通运行情景模拟。基于该仿真平台,研究了预约车辆与非预约车辆混行情景下的个体层面和系统层面的出行效益变化。仿真实验结果显示:(1)预约出行能够大大缓解道路交通拥堵状况;(2)随着预约出行率的上升,出行效益提高,但总体增幅呈减小趋势;(3)重点对途径瓶颈路段规律出行群体和远距离出行群体推广出行预约,能够实现出行效益的大幅度提升。
A simulation platform for travel reservation in urban road based on SUMO is developed to explore the change of traffic benefit brought by travel reservation. In order to realize the simulation of real traffic operation scenario under the reservation mechanism, the simulation platform takes real travel demand as the input of non-reserved traffic flow, and uses the real-time path planning algorithm based on A* algorithm to plan the path for reserved vehicles. Based on the simulation platform, the change of travel benefits at individual level and system level in the case of mixed driving between reserved vehicles and non-reserved vehicles is studied. Simulation results show that: (1) travel reservation can greatly alleviate traffic congestion; (2) with the increase of reservation rate, travel benefits increase, but their overall growth trend decrease; (3) promoting travel reservation for key promotion objects which include group passing regularly through the bottleneck and group traveling long distances, travel efficiency can be greatly improved.
