Abstract

Ranging from simple to sophisticated, numerous types of accessibility measures are found in the accessibility modeling literature which helps to understand accessibility of people, place and transportation networks. Transportation network directness (reciprocal is "circuity"), which is defined as the ratio of the shortest Euclidean distance over network distance between demand (origin) and destination (supply) points, could be considered as an important type of measure for understanding accessibility for a variety of context.
