[Abstract]:With the rapid development of economy and society in our country, the traffic problems caused by the disorderly development of cities, such as the scale of cities and towns, the population concentration and the motorization of cities, traffic congestion, exhaust pollution, etc., are erupting in large and medium-sized cities. The traditional train of thought of traffic development with motorized travel as the target can not solve the increasingly serious urban traffic problems nor meet the increasing travel demand of residents. At the same time, giving priority to the development of public transport has become a common understanding, "public transport city" demonstration construction project, has been popularized throughout the country. In this context, the study of the accessibility of public transport networks will help to enhance the public transport travel attraction, alleviate urban traffic problems, and meet the needs of residents with high efficiency and accessibility. In this paper, the concept of accessibility of urban public transport network is put forward based on the analysis of the current situation of the research on the accessibility of urban public transport networks and the analysis of the factors affecting the accessibility of urban public transport networks. Based on the existing reachability evaluation model, the paper puts forward the concept of accessibility of urban public transport networks. By using the methods of time-space constraint model, topological metric method and cumulative opportunity model, this paper studies the reachability of public transportation network from macro, meso and micro levels, and constructs the evaluation index system of urban public transportation network accessibility. The index calculation model is established. The urban public transport network accessibility evaluation model established in this paper can evaluate the accessibility of urban public transport network in a comprehensive and multi-level way, judge the accessibility level, and find out the defects and shortcomings. The public transportation network database including spatial geographic database and public transportation route system database is designed and constructed by using TransCAD. According to the characteristics of the system, the generalized cost model of public transportation travel path is established by considering the factors such as "transfer times" and "shortest travel distance". Thus, the standard of judging the optimal path of public transport network is determined and the algorithm for calculating the optimal path of public transportation is designed. This paper studies the accessibility analysis of urban public transportation network by using the spatial analysis function of TransCAD software, and extends the function and secondary development of the software by using GISDK,. Finally, taking the public transport network of Lanzhou as an example, this paper analyzes its spatial characteristics, evaluates its accessibility level, and puts forward some development strategies for public transport in Lanzhou. The results show that the theory of accessibility evaluation based on TransCAD can be applied to public transportation.
