Use of Geographic Information System for Analysis of Transit Pedestrian Access

TLDR

The paper describes developing and applying GIS-based transit accessibility measures. The method uses GIS to map neighborhood-level access to routes and stops, integrates land use, population, and employment data, and demonstrates a what‑if scenario for evaluating transit service alternatives. The study concludes that GIS-based transit accessibility measures are useful and can be further developed for planners.

Abstract

The development and application of transit accessibility measures by geographic information system technology are described. The approach allows transit planners to focus on access to transit routes and bus stops at the neighborhood level and draws attention to the significance of the walk access mode to transit. Then land use, population, and employment characteristics are incorporated into the evaluation of transit service. A case study example of a “what-if” scenario for evaluation of transit service alternatives is discussed. Conclusions are offered about the use and further development of the approach for transit planners.
