快充纯电动BRT运营效果评价方法

针对快充纯电动快速公交(bus rapid transit,BRT)系统的运营效果评价问题,提出基于快充纯电动公交车辆运行特性与BRT运营特点的评价方法.首先,分析快充纯电动公交车辆在BRT中的适用性,从运营车辆性能、设施水平、乘客服务水平、经济效益等角度出发,建立包含燃油车辆替换率、动力电池衰减率、充电设施供需平衡关系等9项细化指标的快充纯电动BRT运营效果评价指标体系;其次,采用灰色聚类方法,构建快充纯电动BRT运营效果评价模型;最后,以金华市国内首条纯电动BRT线路为例,进行运营效果评价.与实际运营情况调查结果对比后发现,相比传统BRT运营效果评价方法,该方法更能真实、有效地反映纯电动BRT的实际运营效果.

Evaluation Method for Operational Effect of Fast-charging Electric BRT

Centered on the evaluation issue of the operational effect of fast-charging electric bus rapid transit ( BRT) , a evaluation method was proposed based on the running characteristics of fast-charging electric vehicles and the operational features of BRT system. Firstly, the applicability of the fast-charging electric vehicles applied to BRT system was analyzed. From the perspectives of operational vehicles performance, facility level, passengers' level of service and economic benefit, the evaluation index system for the operational effect of fast-charging electric BRT with 9 detailed indexes including substitution rate of fuel vehicles, attenuation rate of power battery and supply and demand balance relationship of charging facility was proposed. Secondly, the evaluation method for the operational effect of fast-charging electric BRT was established with gray cluster method. Finally, the national first electric BRT line in Jinhua was selected as a case for accessing its operational effect. It shows from the comparison with the survey result of actual operational effect, the method in this study can reflect the actual operational effect of the fast-charging electric BRT more factually and effectively than the method for accessing the operational effect of conventional BRT.
