Efficiency of Motor Carrier Interventions

The Carrier Intervention Effectiveness Model (CIEM) provides the Federal Motor Carrier Safety Administration (FMCSA) with tools to measure the safety benefits produced by interventions. The CIEM does not, however, measure the efficiency of these interventions, in terms of benefits derived per agency dollar spent. This report combines existing CIEM results with recent data from the agency’s 2018 Investigation Cost Survey to provide such estimates. The analysis draws from the Investigation Cost Survey conducted in 2018, which provides a basis for estimating cost per intervention performed. Coupled with data from the CIEM, the information allows for the calculation of expenditure per crash or injury prevented or life saved, broken out by intervention type. The study produced efficiency estimates for two intervention types: on-site comprehensive investigations and on-site focused investigations.
