Full cost analysis of accessibility

Abstract

Traditional accessibility evaluation fails to fully capture the travel costs, especially the external costs of travel. This study develops a framework of extending accessibility analysis combining the alternate (internal and external) cost components of travel, time, safety, emission and money, with accessibility analysis, which makes it an efficient evaluation tool for the potential needs of transport planning projects. An illustration of this framework based on a toy network was also built in this paper, which proves the potential of applying the extending accessibility analysis into the network of metropolitan areas.
