Existing Data Sources That Can Be Used in Conjunction with the Vehicle Inventory and Use Survey (VIUS)

Tuesday, August 19, 2025

The 2021 Vehicle Inventory and Use Survey (VIUS) provides the most comprehensive data on the physical and operational characteristics of the trucks being driven on U.S. roadways. The dataset is a rich resource that can be used to inform decisions regarding investments in transportation infrastructure, vehicle technologies and parts, safety, energy consumption, and more. This report summarizes exploratory research on where and how the value of VIUS could be strengthened through being used in conjunction with other national data sources. The research investigates which data sources are viable candidates for strengthening VIUS, what each dataset’s suitability is for being used in conjunction with VIUS, and what research questions could be answered with the tandem data that result from such effort.
