Abstract:	The Canadian Vehicle Survey (CVS) was developed in 1999 at the request of Transport Canada (TC) to provide estimates of vehicle-kilometers (distance traveled by vehicles on roads) and passenger-kilometers (sum of the distances traveled by individual passengers) by characteristics of vehicles, users, trips, and fuel purchased. It is a quarterly survey using a two-stage design, and it produces both quarterly and annual estimates. The CVS has gone through a major redesign in 2004 to better meet the clients' needs. The main objective was to add a fuel consumption supplement to the trip log at the request of Natural Resources Canada, a new cosponsor of the survey, and for TC to better monitor fuel consumption. In order to keep the response burden as low as possible, changes were made to some survey concepts, including the reporting period. The focus is on the challenge of developing an estimation strategy when each sampling unit has two overlapping but different reporting periods. The estimation of both the sampling variance of a two-stage design and the variance due to nonresponse also will be discussed.
