In the urban transportation planning scene, collecting information on mobility is a costly exercise. Most of the time, it is a multi-institutional, multi-objective and multidisciplinary project. A lot of discussions arise between partisans of a very detailed and extensive questionnaire and promoters of "short and sweet", unambiguous questions about trips made the previous day. Quality, quantity, significance, costs and nonresponse bias are legitimate issues that cannot be satisfactorily answered by a single survey method. Topics addressed in the presentation concern the demonstration of a survey method that integrates a set of technological innovations. Typically designed around the Montreal telephone household survey of 1993, the method illustrates the use of several techniques easily adapted to a standardized microcomputer environment: Cascaded questions focused on household, people living in it and trip characteristics of these people; Direct verification and validation of information fields and logical travel sequence (trip chaining); Interactive geocoding of origin and destination locations, with the help of spatially referenced databases, such as street addresses, street intersections, monuments (main trip attractors organized in suitable categories) and postal codes already structured within a specialized transportation geographic information system; and Systematic interactive validation of trip modal components such as bridges, bus routes taken, subway stations, accessibility, multi-modal behavior, etc. Some of the benefits of the method come from the fact that it uses the same integrated tools employed for transit network-planning modeling and user travel-information systems, these latter having been developed according to a totally disaggregate approach. Moreover, interactive graphics methods are used off-line to reconstruct badly obtained information. In conclusion, the paper demonstrates the current technological capability of conducting continuous telephone O-D surveys to monitor urban mobility in a cost-effective manner.
