Research On The Optimization Of Common Line Bus Scheduling Based On Comprehensive Cost

Nowadays,with the improvement of the level of urban motorization,there are problems such as excessive traffic congestion and parking difficulties in the city.Road traffic is in short supply.How to improve the road traffic problem and make the road more smooth is an urgent problem to improve people’s life satisfaction.Urban public transport aims to provide the largest passenger capacity,which has the advantages of cheap and fast,and plays the most basic role in promoting urban development.The maximum use of urban public transport can reduce the private vehicles on the road and play a role in easing the traffic pressure.Due to the lack of coordination of single line dispatching,the departure interval of each line is not appropriate,and the problems of vehicle utilization,operation efficiency and service quality are particularly prominent.In order to improve the efficiency and service quality of the bus,a more scientific and reasonable bus departure schedule is established.Considering the randomness of the arrival time of the passengers in the common line area,the queuing theory is introduced to calculate the waiting time of the passengers,and the optimization of the bus scheduling based on the comprehensive cost is established The model optimizes the scheduling scheme,and then provides more scientific and reasonable suggestions on the decision-making of public transport operation enterprises,promotes the orderly operation and organization of public transport,greatly improves the operation efficiency and service quality of urban public transport system,and has a certain practical value for the realization of scientific and dynamic control of public transport system,and effectively guarantees the urban public transport The stable,coordinated and orderly development of the traffic line network.
