The objective of this study was to determine various vehicle utilization patterns that are needed to update and verify vehicle activity for emission inventory estimations. The contract, sponsored by the American Automotive Manufacturers Association and co-funded by the California Air Resources Board with the Gallup Organization as the sub-contractor, involved data collection through surveys, data analysis and a report on vehicle usage patterns, focusing on passenger cars and light- and medium-duty trucks. The information collected included the model year and make of the vehicle, odometer readings at the end of each trip, number of passengers during each trip, time and location at the start and end of trip, trip purpose, type of fuel used and refueling events, parking conditions (enclosed garage, open-shaded or exposed area), number of work hours and number of work days per week, etc. Vehicle owners were randomly selected from various cities throughout the United States.
