摘要:

随着电动汽车被引入城市快速公交领域,由于其充换电等特殊的运营调度需求,在发车间隔计划等制定过程中传统方法不再适用.本文在综合考虑服务水平和车辆充电时间约束条件下,对纯电动快速公交(E-BRT)发车间隔优化进行了研究.根据分析服务水平指标项与车辆能耗的相关性,建立了面向能耗评估的服务水平评价体系;综合考虑服务水平和充电时间约束条件,以车辆运营能耗为目标函数,建立了发车间隔优化模型;基于金华市E-BRT1 号线运营数据进行实例验证,结果表明,在满足相同服务水平情况下,本文提出的优化模型可以节约能耗6.21%.本文构建的纯电动快速公交发车间隔优化模型具有较强实用性,为企业在满足一定服务水平的基础上降低运营能耗提供了依据.

Abstract:

With the electric vehicles applied in the field of bus rapid transit, due to the special operational needs of charging or battery swap for electric vehicles, the traditional methods of departure interval optimization are no longer applicable. Considering the level of service and charging time constraints, this paper studies the departure interval optimization of electric bus rapid transit. Firstly, the service level evaluation system associated with energy consumption is established by analyzing the correlation between service level indexes and energy consumption; secondly, considering the level of service and charging time constraints, the departure interval optimization model is established by setting energy consumption as the objective function; finally, taking line 1 of Jinhua E- BRT as an example to examine the effect of the optimization model, the optimization results demonstrate that compared with the current operation plans the energy consumption is saved by 6.21% under the premise of the same level of service. Therefore, the departure interval optimization method of electric bus rapid transit considering level of service established in this paper has certain practical significance and provides an important guidance for reducing the energy consumption under a certain service level.
