Estimating Statewide Vehicle-Miles of Travel: State of the Art Review

Description: This study is concerned with developing a statistical basis for estimating statewide vehicle-miles of travel (VMT) that is consistent with available WSDOT resources, uses of the data collected and appropriate levels of accuracy. The study was conducted in conjunction with, and as a complement to, a more extensive Statewide Highway Data Rationalization Study. In this study, the nature of the problem is first established based on an investigation of users and uses of VMT data and documentation of existing data collection methods. A focused review of the literature is reported, and recommendations are made for a statistically-based methodology and set of procedures for sample design and development. The selection and detailed development and implementation of particular procedures and methodology were not a part of this study.
