本文构建了一个可达性指数来衡量一个地区的整体交通可达性水平。该指数是现有相对和整体可达性衡量标准的自然延伸。理论模型和实证检验表明，该指数具有收敛性，计算准确，成本不高。回归分析表明，该指数很好地反映了地区的整体可达性水平。使用该指数计算美国 60 个最大都市区的总体访问水平。
This paper constructs an accessibility index that captures the overall transportation access level of an area. This index is formulated as a natural extension of the existing relative and integral accessibility measures. Theoretical modelling and empirical tests demonstrate that the index has a convergence property and can be calculated accurately without incurring very high costs. Regression analyses show that the index captures the overall accessibility levels of areas very well. Using this index, the overall access levels of the sixty largest U.S. metropolitan areas are calculated.
