Layout Of Bus Lane For Urban Rail Transit

With the improvement of urbanization level,traffic congestion and traffic pollution are becoming more and more serious.In order to alleviate the current urban traffic problems and realize sustainable development,our country advocates the priority of public transport.At the same time,we should strengthen the integrated development of public transport.An important way to promote the connection between conventional public transport and rail transit and to encourage the priority of public transport is the setting up of bus lanes.The layout scale of bus lanes reflects the level of bus priority development.First of all,the paper expounds the meaning of setting up scale of bus lanes,and then uses demand analysis method,service level method and ridge regression analysis using SPSS calling syntax to build models,and calculates the network scale according to the model,respectively.Using the improved entropy weight method to determine the weight of each model,a comprehensive calculation model is established to solve the problem.Compared with the data obtained by the investment fund estimation method,the reasonable network size of bus lanes in large cities is obtained.Secondly,through the analysis of the setting standards of bus lanes in our country and all parts of our country,the setting conditions of bus lanes are obtained,including the road conditions and traffic conditions,and the advantages and disadvantages of four kinds of bus lanes and their application are summarized.This paper introduces three methods of setting up bus lane isolation mode,analyzes the setting width of bus lane according to the regulations,analyzes three kinds of setting methods of bus stop under different road conditions,and discusses three kinds of setting positions for bus station.Finally,the selection of station distance is calculated and analyzed.Through a large number of literature inquiries,this paper provides the theoretical basis of the following research.Thirdly,this paper puts forward the problem of bus lane layout with urban rail transit,and analyzes it from the two parts of the candidate route set and the optimal route selection technology.In the first part,the Space L weighted network model including public transport network and subway network is constructed,the statistical characteristic index of the modelis used to analyze the current public transportation network,and the section with small weight value is filtered out by using the weight index.The candidate section assembly is selected for the layout design of bus lanes.In the second part,through the analysis of the conditions and principles of bus lane layout,the layout process of bus special lane with rail transit is established,and then the layout process of bus lane is established.The final optimization scheme is obtained by the optimal selection of candidate lines.Finally,taking Tianjin as an example,the reasonable scale of Tianjin bus lane network in 2020 is calculated in the range of 147.8 km to 202.0 km.In this paper,the topological structure model of weighted bus-subway network within the outer ring line of Tianjin is established,and the specific layout of bus lanes is carried out.
