Analysis of Benefits and Costs of Lane Departure Warning Systems for the Trucking Industry

摘要

The Federal Motor Carrier Safety Administrations (FMCSAs) safety goal is to reduce the number and severity of commercial motor vehicle fatalities and crashes. During the last several years, FMCSA has collaborated with the trucking industry to test, evaluate, and facilitate the deployment of several onboard safety systems for commercial motor vehicles to increase the safety of all roadway users. The purpose of this report is to evaluate costs and benefits for industry associated with lane departure warning systems that can reduce large-truck lane departure crashes. The analysis described herein indicates that combination and single-unit vehicles with lane departure warning systems will help to prevent lane-departure crashes. Motor carriers purchasing this technology will likely see net positive returns on investments within a five-year product lifecycle for the crash types and operating scenarios described in this report.
