考虑服务公平性的定制公交动态响应方案

Instant demand-responsive scheme for customized bus considering service fairness

为使车辆在运行过程中能根据乘客即时需求灵活调整线路,提出了一种定制公交动态响应方案。使用节点插入算法为乘客确定备选线路,考虑迟到乘客处理和线路运营收益计算等实际问题。实行“人等车”的机制,合理利用乘客可接受的等待时间,减少误车情况的发生,杜绝拒载现象,保证服务公平性。以河北省雄安新区的定制公交网络验证了模型及算法的有效性,研究结果表明:该方案能在满足乘客时间窗和保障公交运营商收益的前提下,有效应对乘客迟到的情况。

An instant demand-responsive scheme for the customized bus(CB)is proposed,which enables vehicles to flexibly adjust routes according to the immediate needs of passengers during operation. A node insertion algorithm is developed to consider practical issues,such as late passenger handling and profit calculation. The implementation of "passenger waiting for bus" mechanism and consideration of passenger acceptable waiting time reduce the occurrence of passenger’s bus-missing. In addition,strictly preventing the active rejection of loading can also ensure the fairness of CB service. The proposed model and algorithm are verified by a numerical example based on the CB network of Xiong’an district,Hebei province. The results show that the instant demand-responsive scheme can effectively deal with the situation of passengers being late under the premise of guaranteeing the CB system profit and meanwhile satisficing passengers’ service time window.
