【摘要】：针对BRT通道内乘客优化引导问题,文中从BRT快速通道内的乘客需求特性角度出发,根据乘客起讫点(OD)需求与快速通道的线路特点对乘客进行分类,考虑影响在站乘客总效益的各个出行成本(乘车时间成本、延误等待成本和拥挤成本),采用客流分配的方法对到站线路车辆分配不同类型的乘客,并对不同类型的乘客需求采用不同的分配原则,在此基础上建立基于乘客效益最大化的BRT均衡配流模型,并通过设计改进的遗传优化算法对模型进行求解。算例分析表明,该模型可以在满足乘客总效益最优的情况下得到各条线路的乘客分配方案。与不使用该方案相比,算例乘客出行总成本减少162.3元,成本减少17.68%,证明了文中模型的有效性和实用性。
[Abstract]:Aiming at the problem of optimal passenger guidance in BRT channels, this paper classifies passengers according to the demand characteristics of passengers in BRT express channels, according to the needs of BRT and the line characteristics of express channels. Considering the travel costs (travel time cost, delay waiting cost and congestion cost) that affect the total benefit of passengers at the station, different types of passengers are assigned to the arriving line vehicles by the method of passenger flow allocation. On the basis of applying different allocation principles to different types of passenger demand, a BRT equilibrium assignment model based on maximum passenger benefit is established, and the model is solved by designing an improved genetic optimization algorithm. The model can obtain the passenger allocation scheme of each line under the optimal passenger total benefit. Compared with the non-use scheme, the total cost of passenger travel is reduced by 162.3 yuan. The cost reduction is 17.68, which proves the validity and practicability of the model.
