Allocation Of Bus Routes And Stops At An Urban Rail Transit Station

With the acceleration of urbanization in domestic cities,these cities are experiencing the population explosion,where traffic facing huge pressure.Promoting the mode whose backbone is rail transit,mainstay is common transit is the main development strategy of public transportation in China.The current domestic urban rail transit construction is in the high-speed development period,it would be an important part in urban public transport system.At the same time,conventional public transport.,which is the most important transport in urban system,face adjustment.It should be adjusted to improve the transfer efficiency between rail transit and conventional public transport and the service of urban public transportation overall efficiency through the optimization of location of bus stops.After compared urban rail transit systems with regular transit system,analyzed the technology,economic characteristics of the two kinds of the transportation,and the relationship between them,the article proposed the necessity of reasonable connection between rail transit and conventional public transport.The paper discussing public traffic coordination principle in the environment of rail transit system and several common position relations between rail transit station and conventional bus stops.Noticed that the adjustment of location of conventional bus stop which connect the rail transit is the research emphasis.The paper proposed the mathematical model to minimize the total passenger transfer time and the imbalance of passenger flow between the entrance of rail transit station.The Lingo software is used to verify the model through a small-scale case,which is acquired from the rail transit station of Beijing.The pareto optimal set of Lingo result showed the validity of the model to solve the problem.In addition,the paper design the Multi-Objective Differential Evolution based on Pareto Optimality to solve the Large-scale case,the algorithm is proved effective and superiority through the result of Lingo software in the same scale case.Finally,the paper takes the Yongningmen station of Xi'an Metro line 2 and the surrounding bus lines as the case,the model and the algorithm are used to solve.The result shows that the total passenger transfer time can be shorten,and the passenger flow can be distributed in the entrance of rail transit station reasonably.
