中文摘要：

为有效缓解公交车固定发车间隔造成的资源浪费和过度拥挤,以公交运营成本与公交服务能力水平加权和最大为目标,建立了常规公交线路多车型配置优化模型.通过分时段配置不同的车型组合运行,构建了公交线路多车型配置运行模式,最后通过Matlab进行了实例验证,证明该模型能够有效降低固定发车间隔所导致的成本较高以及非高峰时段车辆利用率较低的问题,从而提高了公交车的出行吸引力.

英文摘要：

To effectively alleviate the resource wastes and orercrowding caused by the fixed interval of bus lines,based on the assumption of the fixed time interval,the weighted sum of operating expense of buses and bus service quality was selected as the objective function, through the multi-vehicle-type configuration in the regular bus lines and allocating the different vehicle combinations in different periods.A multi-vehicle-type configuration model was established and strength verification was carried out. The conclusion shows that this model can reduce the high cost generated by the fixed interval and solve the problem of low utilization during off-peak hours effectively by Matlab,thus enhance the attractiveness of the bus.
