城市轨道交通潮汐客流特征下停站时间差异化设置研究OA

At present,the setting of dwell time in urban rail transit rarely takes into account the tidal characteristics of passenger flow in the up and down directions of the line during peak periods.Therefore,it is necessary to conduct more refined research on the differentiated setting of dwell time by direction.Based on the OD passenger flow data of the network,a boarding and alighting passenger flow calculation model was established by direction to convert point-type data such as entry/exit time and location into direction-specific boarding and alighting passenger flow data.Considering factors such as the crowding degree in the carriage,the imbalance coefficient of passenger queuing,and the coefficient of carrying large luggage,a multi-factor differentiated model was created for dwell time setting to accurately match the tidal characteristics of passenger flow in the up and down directions of the line.The platform dwell time of trains in the up and down directions was also set differentially.Finally,with the Xiamen subway operating network as a case study,the model was applied and verified.The results show that the model can significantly improve train operation efficiency,with one-way running time of the line reduced by up to 55 s.The boarding and alighting needs for passengers can be better met,with a 56%average improvement rate of the deviation degree of train arrivals in the direction of heavy passenger flow during the peak hours.The good green energy-saving effects can be achieved,and the average occurrence frequency of trains rushing to meet the schedule in the direction of heavy passenger flow during the peak hours has been reduced by 62%.The boarding and alighting safety of passengers can be effectively ensured,with the number of door entrapment incidents in the rail network decreased by 37%.
