Paper Abstract

Various accessibility measures have been developed for evaluating transit service efficiency. The exponential or logistic type of accessibility model makes use of the phenomenon of distance decay around transit stops, in which distance is a key variable. To reflect the effect of overlapping service between adjacent stops, a weighted distance is developed. The weighted distance is the Euclidean distance weighted by accessible number of transit lines, which is derived either by the integral distance function or the inverse distance weighted interpolation. By combining disaggregated population data, the service capabilities of all bus stops are computed. The stops can be categorized based on the service capability to provide new insight for transit planning and evaluation.
