Study On Medium-Sized Zone Of Public Transit Network Setting

Public transport priority is an effective outlet of solving traffic problem, the key point is to set the public transit network rationally. The paper improves the method of setting transit network by using fuzzy method, statistics and traffic planning theory.Firstly, it sorts out land use again according to transit characteristics and makes out their cluster analysis, on the basis of which it studies the division principle and method of middle-sized zone. Among them, the repartition of land use is based on census data, and has considered the factors influencing transit trip. The method of land use repartition is fuzzy cluster. It adopts differentiating analysis method to decide which classification of the land belongs to.It analyses the dynamic relation between public transit network and the producing amount, adopts multinomial curve and logarithm curve to fit the network index and producing rate data separately, and examine their results, on the basis of which, it also studies the dynamic relation model of network index and the producing rate, and use it to get the middle-sized zone network index.Secondly, it illustrates the confirmation of transit ends should consider the traffic zone area according to the analysis of transit ends confirmation. Therefore it proposes the conforming method in number of transit websites which bases on producing rate. It studies the method of confirming the transit websites of main line and branch line.It analyses the pluses and minuses of routine public transit network. And according to the public transit network, it also studies the method of setting main line based on flow fitness and branch line which based on network index.Finally, it makes out the 2010 year transit network of Liaoyang city by using this method, and verified the rationality of this method.
