Characteristics of Interstate Motorcoach Carriers with Elevated Rates of Crashes and Inspection Violations

This paper reports on a study of the characteristics of interstate motorcoach (bus) carries that have elevated rates of crashes (n = 74) and inspection violations (n = 279). The authors estimated crash and violation rates among interstate motorcoach carriers based on 2005–2011 data obtained from the Federal Motor Carrier Safety Administration (FMCSA). Their principal component analysis produced three orthogonal factors that captured 63% of the total variance in the data set: operating 10 or fewer motorcoaches; being in–business for less than 10 years; and providing non-scheduled route service (as in charter buses). Even scheduled-service motorcoach carriers identified as providing at least occasional curbside service (picking up or dropping off passengers at a place other than a traditional terminal at the origin or destination), had an increased risk of involvement in fatal crashes compared with other scheduled-service carriers. The authors conclude that the FMCSA and the states need to have the resources necessary for close monitoring of motorcoach carriers, particularly high-risk ones such as small and less experienced carriers. Potential countermeasures could include additional regulations, additional contacts between government safety oversight agencies and motor carriers, and incentives to reward good safety records. The authors call for more accurate measures of exposure, including mileage and travel routes, for future research on motorcoach safety.
