Track: Transportation

Abstract

GIS-T is already recognized as an important domain for the analysis of urban transportation context. However, for the visualization of planning and modeling situations, some new tasks have to be deployed to illustrate complex phenomena emerging from large-scale regional telephone-interviewed household travel survey data such as those conducted at a 5 % sampling in Montreal, every five years (400,000 trip records with 80 attributes). Using ArcGIS, several applications about an average weekday are developed: demonstration of the active population dynamics, in space and time, within an urban area, measure of the difference of accessibility between public transport and private car, assessment of the respective residents ’ consumption of road network resources and infrastructures, and estimation of spatial modal shares and vehicle occupancy. Key Words: Origin-destination travel survey, spatio-temporal GIS, urban transportation
