Study On Structure Optimization Of Conventional Public Transport Network In Harbin

The conventional bus network structure optimization is the inevitable choice to cope with the increasingly complicated urban travel environment and the diversified travel demand.With the constant improvement of urban construction,the characteristics of traffic and transportation of urban population have also undergone qualitative changes.The original spontaneous urban public transit network has been unable to match the development needs of the cities in terms of the rapidity and reliability of travel,and has reduced the efficiency of social development.On the other hand,with the climax of urban rail transit construction and the maturity of technologies and applications of BRT,clean energy vehicles and public transportation intelligent systems,it also provides some basis and support for the adjustment and optimization of public transport network structures.Multi-level urban public transportation network structure takes full advantage of the different characteristics of urban public transport modes such as subway,BRT bus and conventional public bus,etc.in terms of transport speed,transport capacity and application scope.Through public infrastructure such as hubs,different public transport The mode is spatially connected to achieve a perfect match between the traffic mode and the actual demand and the physical conditions of the channel.Through the application of vehicle type matching and intelligent bus system,the overall system operation efficiency and the management ability are enhanced.This paper aims to study the technical framework of multi-level conventional bus network structure optimization.Through the research on the interactive relationship between land use and urban public transport,this paper summarizes the traffic space patterns that may be generated by the development and utilization of different land types;analyzes the concept and composition of integrated transport system and how to forecast the traffic demand on this basis;Optimization of the overall idea.In specific research:Taking the hub of passenger station as the core of the network connection,the transportation links and service areas of the hubs of the stations at all levels are determined,and the layout and layout of passenger hub stations are put forward.The objective of optimization and adjustment of the multi-level bus network structure and the constraints of the bus networks at all levels Conditions,and the methods and steps of network planning at all levels;put forward the theory of vehicle size prediction,the standard of line distribution and the selection planning method;put forward the design idea,system framework and data structure of intelligent public transportation system.The multi-level bus network optimization technology framework used in Harbin city bus network optimization and adjustment,planning integrated space system in Harbin City,the spatial layout of the structure and improve the station system hierarchy and spatial distribution of facilities to improve the bus configuration and bus Intelligent system planning,and finally to evaluate the technical performance,social benefits and economic benefits of public transportation network.This paper discusses the interactive relationship between urban land use and transportation as well as the model of bus-oriented urban development.It expounds the concept of "integrated public transport" and the multilevel public transport network hierarchical structure system at the implementation level.Site layout of the hub model,with the level of network relations,the specific implementation of the technical framework.Based on practicality and systematism,this paper builds a comprehensive public transportation network optimization system based on passenger demand prediction,which is based on the optimization of bus routes at all levels,layout optimization of hierarchical transport hubs as the backbone theory,operation vehicles and bus intelligent system as supporting theory theory.Finally,the paper analyzes the urban public transport system in Harbin.The characteristics of urban development environment,the characteristics of urban public transport and development and the challenges of transport development are analyzed.Based on the prediction of traffic demand,the demand and scale of future public transport are quantified and distributed.Optimize and carry out planning research on bus station infrastructure planning,supporting bus development planning and bus intelligent system.At the end of the article,the corresponding technical evaluation and socioeconomic analysis of the research program are carried out.
