Abstract

Accessibility Analysis in ArcGIS Using Generalised Costs
Track: Transportation
Author(s): Alistair Ford, Stuart Barr

Understanding the cost of travel is an essential component of land-use transport modelling. As part of the Tyndall Centre for Climate Change Research 'Engineering Cities' theme, work has been undertaken to model these costs across London under various scenarios up to 2100, and thus describe the changes in transport accessibility which may occur.

This paper will describe the use of ArcGIS and Network Analyst to represent four modes of travel - rail, road, light rail/tube and bus - using network datasets and the use of ArcObjects to provide suitable analysis capabilities. A description of the generalised cost formulation will be provided, covering the workflow from local authority and governmental data to city-wide zonal accessibility costs. Some interesting results under differing future scenarios will also be presented.
