FMCSA Safety Program Effectiveness Measurement: Intervention Model in Fiscal Year 2007

This report presents results from the Federal Motor Carrier Safety Administration's Roadside Intervention Model for fiscal year 2007. The model estimates the number of crashes avoided, as well as injuries avoided and lives saved, as a result of the agency's roadside inspection program. The Roadside Intervention Model uses a risk-based approach to estimates the benefits of the roadside inspection program. With this approach, each violation detected at the roadside is assigned a crash risk. When these violations are corrected as a result of an inspection, the associated crash risks are removed and the number of crashes, fatalities, and injuries prevented can be estimated.
