Evaluation of Violation and Capture of Overweight Trucks: A Case Study

Description: This report concludes the four phase evaluation of Washington's fee and fine system. The primary focus of this report is the occurrence and capture of overweight vehicles at three selected evaluation sites in Eastern Washington: Pasco, Chattaroy, and Cashmere. Weigh-in-motion data were utilized to determine any changes which occur in truck traffic when weigh stations are open and closed. Violation rates are estimated between 20% and 22% with capture rates between 20% and 27%, depending on the site. Violation and capture rates, in addition to truck volume and axle weights, are further calculated for different truck types during all hours of the day. The analysis also includes seasonal variations in all variables.
