Abstract

The main purpose of this paper is to define the concepts and measures of accessibility used in various disciplines. To do this, a significant literature review was conducted particularly in fields of traffic engineering, transportation planning, urban economics, urban planning, and geography of transportation. The result indicates that each discipline uses the concept of accessibility in a slightly different perceptual framework and thus shows somewhat ambiguous definition. The result also indicates that accessibility should serve as a tool to integrate transportation planning into the other connected disciplines.
