Research On Bus Routes Optimization Of Community Microcirculation

Latest years,with the rapid development of China's urban transit system and the growing size of cities,the travel mode of citizen changed from the previous single-mode into multi-mode coexistence.The full use of urban rail transit efficiency in urban public transit system depends on the coordination and convergence of the ground conventional bus.Only by vigorously developing the public transit system with complete and coordinated functions,especially the community microcirculation bus routes,the terminal of city public traffic network,can attract urban residents to public transit and realize the true sense of the bus priority.This paper study the optimization of community microcirculation bus routes path in the road trarnsport network.Firstly this paper expounds the relevant characteristics of the bus route,positioning the community microcirculation bus routes,and analyzes the optimization objectives and constraints of the community microcirculation bus route optimization problem.For the existing mature traffic zone,based on the three angels of passenger,bus companies and society,this paper established a multi-objective optimization model for single community microcirculation bus route path.For the newly built and immature traffic zone,this paper introduced the index of potential passenger for route path and based on this index,established a multi-objective optimization model of which the optimization direction is maximize operation benefits and minimize operation costs for the public transport enterprise to find out the solution to optimization issue of community microcirculation bus route path sets.And also according to the data the model require,established a data screening system and operating procedures.Then,using the search optimization algorithm and the shortest path method to solve the issue of single community microcirculation bus route path optimization and verified by an example.Using genetic algorithm to solve the issue of community microcirculation bus routes path sets optimization by a simulation example.Finally,the results showed that the model and the method is reasonable and feasible.This paper aims at the construction of new theories and methods for community microcirculation bus route optimization and meet the actual demand and make a better solution to passenger's last mile trip problem.
