Research on evaluation of location planning for urban public service facilities based on GIS spatial analysis

Following the extensive urbanization, more and more people swarm into cities. Demands for urban infrastructure and land use, therefore, will change rapidly and drastically, and most urban planning should be regulated or remade. Under the new situation, location of public service facility should be paid more attention to, while the general software platform could not assist it well. Therefore, a new kind of traffic network system is proposed, which is composed of both vehicle traffic model and pedestrian traffic model, and corresponding algorithms are built or rebuilt. Moreover, the evaluation indices are proposed to evaluate different location planning scheme. Finally, new models and methods are used in location analysis for urban public service facilities in case cities, and show the effectiveness.
