Intermodal Contour Accessibility Measures Computation Using the 'UrMo Accessibility Computer'

Abstract

Contour accessibility measures form a set of performance indicators used to value a location by the amount of accessible activities, places, or space within certain time or distance limits. They are used for evaluating a region's activity potential taking the connectivity to its surroundings into regard and act as input data for land use planning models and traffic demand models. With the availability of disaggregated data and sufficient computer power, accessibility measures can be computed at a very fine-grained level of single buildings, points of interest or areas. This approach considers single routes through the transportation network and allows for computing intermodal accessibilities which assume a usage of multiple carriers along a single way. This report presents a tool that realizes such a disaggregated computation of accessibility measures. A strong focus is put on the tool's internal computation steps for supporting a reference to potential users.
