And then take theory research and comparisonresearch method, investigate the existing accessibility model, this paper summarizes theadvantages and disadvantages of each model, and focus on the influence factors of evaluationmodel. According to the problems, this paper put forward two new accessibility systemevaluation model, a quantitative model and a fuzzy evaluation model. At last, take Tianjin to asan example of the new model case study, sums up the effectiveness of the model and method, thematters should be paid attention in practical application, and finally points out the future researchdirection.
