Jiaxing to Fengnan Suburban Railway is Jiaxing City's first suburban railway and an important part of the multi-level rail transportation network of the Yangtze Delta region.It is also interconnected with the Jiashan to Xitang Suburban Railway,reflecting the trend of suburban trains cross-line operation.Designing the train operation scheme is crucial for organizing the suburban railway,and a major task during the operation period,as well as an essential consideration during the planning and design stage.In this study,we constructed a mathematical model based on the general situation of Jiaxing to Fengnan Suburban Railway.Using different types of trains operated in the suburban railway and with optimization goals of maximizing the total travel time of all passengers,we developed a series of optimization models of train operation schemes under the condition of interconnection.These models include the calculation model of the number of direct trains of suburban railway,selection model of the stop site of express trains,and calculation model of the number of express trains and trains stopping at all stations.Through analyzing the interconnection of Jiaxing to Fengnan Suburban Railway and passenger flow prediction results during peak hours,we determined that the train operation mode of Jiaxing Nan station to Nanfeng line should be the express/slow train organization mode,with the express trains stopping at Kejicheng and Jiashan stations.The number of direct trains should be one pair per hour,the number of express trains should be three pairs per hour,and the number of trains stopping at all stations should be five pairs per hour.The train operation mode of Jiaxing Nan station to Shifanqu line should also be the express/slow train organization mode,with the express trains stopping at Kejicheng,Jiashan and Xitang stations.The number of express trains should be two pairs per hour,and the number of trains stopping at all stations should be six pairs per hour.Finally,we formulated the train operation scheme of Jiaxing to Fengnan Suburban Railway.
