A GIS Based Model for Land Use and Transit-Integrated Corridor Optimization

摘要

Based on the conception of Transit-Oriented Development (TOD) and sustainable development, this study aims to establish a GIS based model for integrating land use development along transit corridors. The purpose of the model is to optimize and integrate the development of land use and public transit. Considered factors include accessibility measurement, economic benefit, environment impact and transit. Based on these factors, the integrated model is composed of four sub-objectives, taking the situation of the Chinese city into account. A TOPSIS approach is designed to integrate the four sub-objectives. An optimization modeling software (Lingo) is used to build and solve the linear programming models. A loose-coupling approach was applied to integrate basic data in ArcGIS and modeling results from Lingo. Preliminary results will be presented, and restrictions of application are discussed.
