Pedestrian route choice behavior is affected by numerous factors. A lot of research has demonstrated that the route length or distance is one of the most important. Since distance is related to the network topology, it is desirable to incorporate network topology into pedestrian route choice behavior models as a variant. However, unfortunately, although there are some conceptual or graph-theoretical studies concerning network topology analysis, the studies concerning the real existing network remain uncultivated, especially from the perspective of pedestrians. After reviewing the previous studies, this paper proposes a new classification methodology which facilitates the topology analysis of real existing networks by using Geographical Information Systems (GIS). Considering the pedestrian's distance priority, this paper points out the existence of one-route OD pairs i.e. the OD pairs without alternative routes, and discusses their relationships with network topologies.
