Tools to Create Network-Based Accessibility Grids for Land Use Modeling
Track: Urban and Regional Planning
Authors: Abdulnaser Arafat

The coordination between land-use and transportation has been the focus of several research studies. Transportation impacts land use and land use impacts transportation. Traditionally, the land use-transportation planning cycle is one of the main causes of urban sprawl. The construction of freeways facilitated mobility and urban expansion which in turn generated demand for more freeways. Researchers have identified this problem and recommended planning for accessibility instead of planning for mobility.
The Land Use Conflict Identification Strategies (LUCIS) is an automated GIS based land use modeling system that uses suitability and Criteria Evaluation Matrices (CEMs) for envisioning future growth. However, LUCIS uses Euclidian proximity and point density grids to model accessibility to services. This paper will introduce new tools created by Model Builder, Python and geo processing objects to create accessibility grids based on network distance/time as well as service density and attraction.
