Comprehensive Optimization of Routing Plan and Timetable of Urban Rail Transit Based on Nested Rail Route
摘要
Abstract
Because of the high utilization efficiency of transport capacity and a wide range of passenger flow radiation,the nested rail route has great significance for improving the organization and management of urban rail transit operations.Existing studies of the nested rail route are generally based on the multiple relationships between the departure frequency of different trains or the same interval between train departures within a set unit time period(often one hour or more),which makes it difficult to resolve the contradiction between transport capacity supply and time-varying passenger flow demand.According to the OD demand of the passenger flow in different periods based on differential passenger behaviors,this paper constructed a comprehensive optimization model of the routing plan and timetable in the nested rail route mode,designed a hierarchical optimization algorithm,and used an example to verify that the maximum full load rate of the optimized line has dropped by 0.397;the full load rate balance has dropped by 15.5%,and the optimization effect of interval with a full load rate of more than 0.8 is 100%.This helps to improve the adaptability of transport capacity to time-varying passenger flows and realize high-quality and fast transport service.关键词
