MOTOR CARRIER INDUSTRY PROFILE STUDY: EVALUATING SAFETY PERFORMANCE BY MOTOR CARRIER INDUSTRY SEGMENT

摘要

The primary mission of the Federal Motor Carrier Safety Administration (FMCSA) is to prevent commercial motor vehicle-related fatalities and injuries. The FMCSA contributes to ensuring safety in motor carrier operations through public education and outreach, as well as regulatory enforcement. The motor carrier industry is highly diverse and competitive, comprised of many unique types of operations and hauling many different types of commodities. In an effort to better understand the diverse nature of this industry and explore safety and operational differences among its major segments, the FMCSA, with the University of Maryland, College Park, undertook the Motor Carrier Industry Profile Study. This paper examines the recent safety performance of 11 for-hire and 10 private segments of the motor carrier industry. The safety performance differences between individual segments are examined, as well as the differences between the for-hire and private sectors as a whole. In this analysis, safety performance is evaluated according to two driver-related safety measures, two vehicle safety measures, three crash-related measures, and two safety management performance measures. The study used the Motor Carrier Information Management System (MCMIS) and the Motor Carrier Safety Status Measurement System (SafeStat) as its sources. The MCMIS and SafeStat are maintained by the FMCSA and are populated with data from roadside inspections, FMCSA and State compliance reviews, crashes, and enforcement cases against motor carriers.
