A GIS-based land use and public transport accessibility indexing model

摘要

Accessibility indexing is important in evaluating existing land use patterns and transportation services, predicting travel demands and allocating transportation investments. A GIS-based land use and public transport accessibility indexing model has been developed for measuring and mapping levels of accessibility to basic community services by walking and/or public transport, within local government areas. The model aims to assist the planning and decision making process to deliver integrated land use and transportation outcomes. It is an origin-based accessibility model that determines levels of accessibility by utilising GIS analysis techniques to measures accessibility based on both actual walking distances and public transport travel time. The model has been applied to two pilot studies in the Gold Coast City to assess its practicality and effectiveness. This paper outlines the methodology of the model and the findings related to these pilot studies. The paper also demonstrates benefits and application of the model to other urbanised local government areas.
