Optimization Of Public Transport System In WuZhong City

With the acceleration of urbanization and information technology,the development of urban public transportation has entered a period of rapid development.It is an important task for the traffic managers to provide good traffic support for the livable city construction and provide good transportation services for the residents.Based on the development goal of urban and rural public transport integration in the future of Wuzhong City,through studying the current situation and existing problems of public transportation in this area,and drawing on the development experience of urban public transportation at home and abroad,using the bus optimization theory to optimize the ?The first part studies the development status of the theory of public transport network optimization at home and abroad,and then puts forward the research contents and technology roadmap of this paper.Secondly,it analyzes and evaluates the development status of public transportation in Litong District of Wuzhong.Third,we study the theory of bus route optimization,set up the multi objective optimization model of line network optimization by setting the optimal constraint conditions of urban bus line network,and through the construction of rapid traffic,adjustment and improvement of conventional public transport,and form a variety of ways of efficient and coordinated development of public transport system.Fourthly,using the comprehensive growth rate and linear regression model to predict the population development status in Wuzhong City,and forecasting the occurrence and production of traffic in Wuzhong with double-constrained gravity model and multiple linear regression models.Fifth,based on the overall planning of Wuzhong City,to facilitate the residents' behavior,combined with the results of current surveys and forecasts of public transport OD,the planned layout of the existing passenger bus lines in Wuzhong will be planned.The alignment of the existing lines,site settings,etc.,are adjusted,or new public transportation lines are opened up.The combination of regular public transport and featured public transport will create a multi-functional,multi-level integrated public transportation network system.Sixth,on the basis of optimizing the road network structure,the “intelligent bus system” and “intelligent IC card settlement system”for public transport integrated video surveillance,GPS and information systems will be planned and constructed to comprehensively improve the level of public transport service and supervision.Finally,the evaluation of the optimization scheme proposed in this paper was compared and satisfactory results were obtained.
