摘要
模拟导弹制导的单车诱导算法利于交通系统优化目标(车流量平衡目标).为避免多车诱导导致的交通拥堵,以模拟导弹制导的单车诱导算法为基础,提出了模拟导弹制导的交通系统路径诱导算法.按照出行需求,对模拟导弹制导的时间最短路径算法进行改进,使算法满足各类单车路径规划目标,以提高单车诱导接受率.系统路径诱导算法以交通系统优化为最终目标,对超出路网通行能力的诱导进行修正,使交通流运行趋势符合驾驶员出行需求.建立系统优化评价指标和系统诱导接受率指标,并以北京部分地区为例进行仿真.仿真结果表明,算法能够达到系统优化目标,同时保证了较高的系统诱导接受率.
A simulated missile guidance algorithm is useful for single-vehicle path planning to achieve the system optimization objectives（vehicle flow balance objectives）. To avoid traffic congestion caused by a planning algorithm in which multiple vehicles adopt the same path, a simulated missile guidance algorithm for traffic system path planning was proposed based on a simulated missile guidance algorithm for single-vehicle path planning. The least-time path algorithm based on missile guidance was improved in response to drivers＇ travel demands. The improved algorithm can be applied to all types of single-vehicle path planning objectives and can enhance the guidance acceptance rate. The ultimate goal of the system path guidance algorithm is to optimize the traffic system. To make the traffic flow tendency conform to drivers＇ travel demands,it modifies the guidance when the road network capacity is exceeded. A system optimization evaluation index and a guidance acceptance rate index were established. An area of Beijing was taken as an example, and the results show that the algorithm can achieve system optimization and ensure a high guidance acceptance rate.
