Research And Application Of Vehicle Bus Combined Scheduling Model For Urban Public Interval Bus

With the background of population's rapid growth,the urban traffic congestion problem caused by increasing demand of citizens'travel request have become more and more significant.Developing a city's public traffic in high priority,which is the most effective method to resolve the illness of the public traffic.The key to public traffic is the buses' coordinating,it took a serious influence on both of the quality of passenger's outdoor life and buses' firm operating costs.The traditional single type of buses' arrangement is too hard to satisfy passengers' demand in the case of unbalance distribution of passenger flow.The interval bus used as a kind of assist method to be processing in a certain period of whole trip,it takes rid of the contradict from the passengers' demand and buses' coordination.This page provided a brief research on the mode of buses' coordination in a city.At first,this page has considered the amount of awaiting transited due to the buses'capacity and the buses' normal picking time due to passengers' get off etc.It uses the combination of passengers' costs and bus firm's weighted data as aimed function,the mode of starting buses' and the departure interval as decision variable,to build a urban interval bus combinatorial scheduling model.It designs the genetic algorithm suitable for this model,in order to get the combinatorial scheduling scheme that fits for the actual operation situation.Secondly this page also studies about data processing and the analyze method,what's more,it has realized the interval buses' originally operating system.It is essential to get the exact date to built the suitable groups arrangement.It also has combined the moment IC card checked times and the GPS data to make an exact prediction about every station's passengers flow and predicted the number of stations to get off using the number of getting on.Based on the number of stations up and down,it has provided data basis for the determine of interval bus stops and solution of combinatorial scheduling model by means of probability model for calculating OD matrix of passenger flow.At last this page has picked the history routine data of a bus in a city to make the expected combinatorial scheduling model of interval buses,also compared with actual operating situation to prove its effectiveness and feasibility.Conclusion from the practice,the paper's achievement has certain theoretical and practical value to improve the quality of citizen travl and the level of public transport operation.
