California Vehicle Inventory and Use Survey Pilot Study
The purpose of Cal-VIUS is to provide updated and relevant detailed truck inventory and activity data from trucks that have operations within the State of California to government agencies, businesses and academia who are interested in commercial vehicle activity and freight transportation. It will serve an update to the California portion of the national VIUS effort, which was last conducted in 2002. The pilot study was conducted to design the sampling framework and the survey instrument, and then provide guidelines for the actual Cal-VIUS. A stratified random sampling is adopted to capture key population characteristics for commercial vehicles with a variety of attributes. The survey instrument is an online questionnaire with questions designed to gather key data needed by stakeholder agencies.
