Title:

Cost–Benefit Analysis of Four Large Truck Advanced Safety Technologies

Accession Number:

Abstract:

The objective of this study was to provide scientifically-based estimates of the societal benefits and costs of four large truck advanced safety technologies: automatic emergency braking (AEB), air disc brakes (ADB), lane departure warning (LDW), and video-based onboard safety monitoring (OSM). For each technology, benefit-cost analyses (BCA) were performed for installing the technology on all large trucks (including retrofitting existing trucks) and for equipping new large trucks only, and were performed for equipping only single-unit trucks, only combination-unit trucks, and all large trucks. Sensitivity analyses examined three cost estimates (low, average, high; values technology-specific), two estimates of system efficacy (low and high; values technology-specific), and three discount rates (0, 3%, 7%) for each technology. A literature review and expert advisory panel informed estimates of efficacy and costs for each technology. Equipping trucks with video-based OSM systems was found to be cost effective for all combinations of costs, efficacy, and discount rate examined, for all truck types including both new and existing trucks. LDW systems were also found cost-effective under almost all scenarios examined. Results for AEB and ADB were mixed. Only the low cost estimate was cost effective for all large trucks regardless of efficacy rate, and ADB was also cost effective at an average cost. However, all cost estimates were cost effective with a high efficacy when only equipping new large trucks. Overall, these data suggested all four technologies can be cost-effective for new large trucks provided the current costs and efficacy rates can be maintained or improved upon..
