This study aims to develop a model for evaluating the connectivity of a multimodal transit network. In order for the model to well represent characteristics of a multimodal transit network, connectivity should be analyzed based on nodes and transit lines of the network instead of nodes and links. The degree centrality of a node, which is a commonly used concept in social network analysis, is employed with appropriate modifications so that it is suitable for connectivity analysis for multimodal transit networks. As the representative characteristics of a transit line, the authors select its daily capacity, average speed, and length. The authors then define the connecting power of the line as the product of those quantities. Using the degree centrality of a transit stop and the connecting powers of transit lines serving the stop, the authors develop an index quantifying the level of connectivity of the stop. The authors also derive the connectivity index of a transit line as well as an area within the network from the connectivity indexes of transit stops. The authors show that the connectivity indexes of transit stops can be used to evaluate the connectivity of a transfer center. The connectivity evaluation model developed in this study takes well into consideration characteristics of multimodal transit networks, adequately measures the connectivity of transit stops, transit lines, and areas, and furthermore can be used in determining the level of service of transfer centers.

The DVD lists the title of this papera as: Model for Evaluating Connectivity of Multimodal Transit Networks.
