This paper describes results of the Region of Peel Commercial Vehicle Survey, a pilot data collection effort that collected commodity, mode choice, and commercial vehicle movement data from a sample of approximately 600 shippers and a sample of their drivers, in the Region of Peel, located just west of the City of Toronto, Canada. Two survey techniques are tested, including a mail-out/ mail-back survey and a mail-out/ mail-back survey with a GPS-supplement. This paper describes the survey method, the results and the methodological lessons learned in the urban goods movement study. A comparison of survey implementation results for the two types of surveys are provided, including overall survey response rates and item non-response. Analysis of the quality of shipper, driver and GPS portions of the data are outlined with checks for consistency. Comparisons of commercial vehicle tour behavior and stop location and time as reported in the paper survey forms and as recorded in the GPS units are made for an evaluation of the effectiveness of the GPS in identifying stops, and the potential of GPS as a passive replacement for more traditional paper and pencil survey methods.
