Origin-destination survey data dissemination in metropolitan context : A multimedia experience

Since the early 1970s, the Montreal Urban Community Transit Commission has held a series of six major origin-destination surveys in the greater Montreal area. These studies, which include approximately 50,000 households per survey, benefit from a totally disaggregate approach. This framework permits the spatialization of each trip end at the x-y coordinate level and associates multiple variables to every recorded trip. The dissemination of such a vast quantity of data requires different levels of resolution with respect to processing methods and software, zonal aggregation, itineraries, and sociodemographic variables. In this context, two tools have been created for public use: MADEOD (Origin-Destination Survey Data Disaggregate Analysis Model) and MADGEN (Trip Generator Disaggregate Analysis Model). Because of the recent and rapid evolution of multimedia technology, these tools have been developed in an interactive Microsoft Excel worksheet format and in hypertext markup language for the Groupe MADITUC's World Wide Web site on the Internet. Stand-alone multimedia presentations and a Windows help file have also been developed for tutorial use.
