Theory And Practice Of Metro Network Planning

In the 21st century, Urban Rail Transit has become an important development strategy for urban traffic in China, and also a significant infrastructure for solving traffic problems in large cities. Within city and its related region, systematically, rationally and scientific future planning for Rail Transit routes and its network, and its compatibility with land use plan for specific geographical form and mater plan of city, are common problems met by large cities planning for Rail Transit systems in China. Proper selection of network scale and its rational form for improving accessibility is also included in these problems.On the basis of studying vast research papers and reports on city traffic plan and Rail Transit plan, the significance of Urban Rail Transit plan is stated in this dissertation, current problems concerning Urban Rail Transit plan are also discussed. Main contents of Rail Transit plan are firstly introduced in this paper, Rail Transit network scale is also discussed and the concept of rational network scale is introduced. Rationality of network form is very important because it relates to accessibility and the attracted quantity of traffic. Multi-index calculation for medium/small network form is carried out in this dissertation, graph theory and network flow theory is also used for topological analysis for medium/small network. Establishing of evaluation index systems needing for evaluating of different plans is described in this dissertation. At last, taking Chengdu City as example, following the materials discussed above, the whole program of Rail Transit plan is systematically discussed, base on analysis and evaluation of network plan, some suggestion is put forward, which can be important references for engineering.
