摘要
为提高公交运营质量,基于综合成本优化研究公交多模式站点停靠方法,首先考虑公交通行能力、客流关系、时间关系、发车间隔和满载率等约束条件,分析停站模式的影响因素及定量化表示;其次建立以乘客出行成本和公交运营成本最低为目标的参数优化模型;最后设计基于遗传算法的求解算法并给出算例。利用实际案例对模型进行求解和验证,结果表明:高峰小时采用多模式站点停靠方法后,乘客出行和公交运营综合成本较未优化前降低51.1%。
In order to improve the quality of transit operation,the multi-mode optimization of bus stopping based on comprehensive costs was studied.Firstly,with the consideration of various constraints,including bus transit capacity,passenger volume,time and capacity rate,the influence factors of stop mode were analyzed and quantification representations were given.Then,models based on minimizing passengers' travel costs and transit vehicles' operation costs were established.The algorithm based on GA was given to solve the model.A case study was carried out to verify the correctness of the model and the effectiveness of the algorithm.The results indicate that the comprehensive costs of passenger costs and bus operation costs can reduce by 51.1% after the application of the multi-mode of bus stopping method in rushing hours.
