Pilot Study On The Urban Public Transportation Network Planning

As the main part of the urban passenger transport planning, public transportation network, planning plays a very important role. After analyzing the features of urban public passenger transport, a strategic idea that the public passenger transportation system is formed muti-gradually by Light Rail (LR) as its framework, normal public transport as its main part and other public transport manners, is studied.By Using the LR as the example, an improved scanning algorithm is put forward for the medium quantity rail transport. According to the practical conditions, and with the aim of maximum route efficiency, both qualitatively and quantity, the route-searching range is diminished gradually until best LR route is found. Meanwhile, the method for setting the terminals LR routes and the passenger flow forecasting method are also studied.In order to extend the passenger-attracting scope, the method for feed bus route planning is developed. In this process, the method for selecting the feed bus terminals is the primary part. With the feed bus terminals as the foundations, a series of reasonable feed bus routes are selected step by step. These routes, together with the LR network, form the framework in the urban public passenger transportation system.After the former planning methods for normal public transportation network are summarized and concluded and the method for setting urban passenger exchanging pivots is analyzed qualitatively, a heuristic method for normal public transportation network is put forward. By the Consecutive feedbacks, a reasonable public transportation network is formed. Meanwhile, the methods for setting the terminals of normal public transportation routes are improved.The methods for public passenger transportation networks planning are applied in the Ansan city comprehensive public passenger transportation planning. The LR route planning, LR passenger forecasting and normal public transportation network planning are Carried out successively, and the planning outcome is satisfaction.
