Résumé
Literature has recognized the influence of numerous factors on urban mobility: demographics, income, transport supply, motorization, employment, women participation to workforce, etc
These factors are also largely influenced by land use. Moreover, when urban sprawl is becoming a continuous process, transport planners need a better understanding of the underlying dynamics of the changing mobility markets.
The goal of this paper is to characterize several trends that have been observed when analyzing the following key sub-populations in the Greater Montreal Area: workers and employers, students and schools, shoppers and shopping centers. Data come from two comparable 5%-sampled telephone interview Origin-Destination surveys conducted in the falls of 1987 and 1993. These surveys make use of geo-referenced locations within a GIS-T environment for processing associated residences, trip origins and destinations (trip generators). A totally disaggregate analysis approach is used to calculate related traveler and travel attributes.
In addition to graphically representing areas where new households are settling in the recent years, trip generators are also looked at as a by-product of urban sprawl. Several sprawl indicators are derived to show mixed behaviors according to the transport object in focus: household, population, cars, jobs, generators. New distribution of travel distances and related consequences on modal split and transit usage are to be characterized accordingly. |
