| Urban transportation is the key to the modernization of the tandem city and the sustainable development of the economy.The convenient and smooth urban transportation also has a direct impact on the economic efficiency and function development of the city,and can improve the living environment and quality of life of the citizens.With the rapid development of the urban economy,the problem of urban traffic congestion has been aggravated,and the role of public transport in the development of urban transportation has also been highlighted.How to increase the attractiveness of the public transport system,how to attract urban passengers more to public transportation,and make the city’s roads smoother,smoother,and smoother,will become very important.Bus dispatching is a core part of the operation of urban public transport systems.Proper bus dispatching can greatly ease the contradiction between bus transportation capacity and passenger flow,and can also greatly balance the interests of bus companies and passengers,making it more convenient for residents to travel,and at the same time the economic and social benefits of public transport companies are better..How to formulate an efficient and reasonable method of bus dispatching,improve the level of public transport services,and improve traffic congestion in recent times has become an important issue in the current urban development process.Whether the bus dispatch is scientific and reasonable depends not only on the correct setting of the bus departure schedule,but also on the type of bus dispatching method chosen.The rationality of bus dispatching can be ensured through the distribution of passenger flow on the line,selecting the appropriate bus dispatching method,and formulating a reasonable departure plan.At present,there are relatively few researches on the combination dispatch of urban public transport vehicles in China.The general research is on the combination of full-vehicle and large-station express trains,full-vehicle and shuttle buses,and the three dispatch methods are combined.There are fewer studies,so this article does some in-depth analysis and discussion in this regard.This article analyzes the composition of bus passenger flow and studies the optimization of bus dispatching.First of all,it mainly analyzes the composition of public passenger flow,which shows that the change of passenger flow is the main reason for the congestion of bus lines.Secondly,in the course of the operation of public transport,real-time tracking,forecasting and systematic analysis of the dynamic changes of passenger flow,understanding the law of passenger flow changes and the existence of imbalances in order to ensure the smooth operation of public transport system operations,in addition,passenger flow Real-time changes are also the characteristics of the public transport system itself and the characteristics of urban socio-economic activities.Finally,through the related literature theory,using the passenger flow time distribution characteristics,passenger flow spatial distribution characteristics and passenger flow transfer characteristics,the bus traffic scheduling model in urban traffic congestion was studied.Through theoretical and data support,the 906 bus operation organization model in Zhengzhou City was deeply analyzed.And characteristics,re-determined the bus dispatching model,established mathematical models based on various unbalanced coefficients,and then solved the passenger flow data to determine the mode of operation of public transport vehicles during the peak congestion period,the time interval of departure and the number of vehicle configurations,and finally obtained Zhengzhou City 906 bus vehicle scheduling model. |
