MODELING STREET CONNECTIVITY AND PEDESTRIAN MOVEMENT ACCORDING TO STANDARD GIS STREET NETWORK REPRESENTATIONS 018

Abstract

We study three 1 mile x 1 mile areas in Atlanta to establish correlations between street configuration and densities of pedestrian movement. Two kinds of analysis are used: first, standard syntactic analysis applied to axial maps drawn to cover surrounding areas large enough so that Radius 3 Integration values assigned to observation spaces suffer no edge effects; second, new techniques of analysis that can be applied to standard GIS representations of street center-lines. It is shown that the new measures post-dict movement densities as well as the standard syntactic measures. Can Alternative Measures of Street Connectivity be Used to Express Hypotheses on the Theory of Natural Movement? The relationship between the distribution of pedestrian movement and the spatial structure of street layouts is well established (Hillier et al
