You can access information to learn about the effectiveness of these programs in terms of crashes and reducing the number of related injuries and fatalities based on two models: the Compliance Review Effectiveness Model and the Intervention Model: Roadside Inspection and Traffic Enforcement Effectiveness Model (A).

The Compliance Review Effectiveness Model was developed to measure the effectiveness of the CR in terms of crashes avoided, injuries avoided, and lives saved. The results of the model show the benefits of the CR and also illustrate that certain motor carriers respond to CRS (i.e., lower their crash rates more) than other motor carriers.

The Intervention Model is based on the premise that Roadside Inspections and Traffic Enforcements —directly and indirectly contribute to a reduction in crashes as a result of the intervention.

The results of these two models are presented as one-page summaries and detailed technical reports located within the Program Effectiveness sub-module and can be used by FMCSA managers to study the effectiveness and benefits of implementing these important safety initiatives. (B)
