| 摘 要： | 为研究可行的城市对外交通枢纽可达性测算方法,在分析总结现有研究成果和存在问题的基础上,对城市对外交通枢纽可达性进行了定义. 提出通过快捷程度、经济程度和舒适程度描述枢纽可达性,并选取相对应的时间、费用和疲劳成本作为量化基础. 针对现有枢纽可达性测算模型的不足,建立了改进的基于有量纲法和非集计模型的可达性测算模型体系和测算方法,结合具体案例进行了分析,测算结果验证了模型的正确性和可行性.

| Abstract: | The feasible accessibility of external transportation hub in urban area was studied in this paper. The definition of accessibility for transportation hub was represented based on the analysis and summary of the previous research and the existing problems. The accessibility of urban external transportation hub was described by the indicators including travel time, cost and comfort. The accessibility was quantified by the time costs, economic cost and fatigue of travelers. According to the disadvantages of current hub accessibility model, an improved accessibility calculation model based on dimensionless method and disaggregate analysis was proposed. The validation and feasibility of the new model were verified by a specific case study. |
