Optimization of public transit network caused by adjustment of land use

Abstract

The optimization problem of the urban Public Transit Network has been caused by the adjustment of land use during the process of urbanization in China. Combined with the system analysis method (ISM), two core issues have been solved in this paper: (1) how to generate the theory of optimal line network and (2) how to adjust the original line. The improved “ant colony algorithm” method has been used in accordance with the principle that: “one by one wiring and optimization is needed to develop a network”. This introduced the optimal bus network theory, comparing the new and the old network, using the “pruning” line adjustment method. The optimization scheme of transit networks, verified the feasibility of the method through the instance and provided reference for urban road network optimization that caused by adjustment of land use.
