需求响应公交接驳小车路径规划研究

摘要

针对不同公交方式接驳中出现的乘客直达性不高等问题,研究了需求响应公交接驳小车的最优接载路径.对乘客接驳小车的使用意愿和支付意愿进行了调查并分析,以乘客价格和车辆费用最优为目标函数,建立了需求响应公交接驳小车最优路径规划模型.并使用遗传算法,对该模型进行了求解.通过实例,验证了该模型的可行性和有效性.计算结果表明:该模型能够有效地搜索出费用和收益最优的接驳小车乘客接载路线.%Optimal route planning for the demand responsive transit feeder car was in-vestigated to solve the problem that passengers can't reach the destination directly through connections between different public transport modes.After the investigation and analysis of the passenger's willingness-to-use and willingness-to-pay of demand re-sponsive transit feeder car,optimal vehicle route planning model for the demand respon-sive transit feeder car is established based on passenger's willingness-to-pay,which use passenger's price and vehicles operating cost as the obj ective function.After that,genetic algorithm is used to build the model.Then,an example is introduced to verify the feasi-bility and effectiveness of the model.Finally,a conclusion is drawn that the model can effectively work out the optimal vehicle route planning of demand responsive transit feeder car based on the vehicle cost and passenger's price.
