• Abstract:
  The purpose of this project was to quantitatively identify detention times in the commercial motor vehicle (CMV) ; industry. Although there is currently no standard definition, the industry commonly defines detention time as “any ; time drivers have to wait beyond 2 hours, which is the average time it takes to load or unload their cargo.” Results ; indicated that drivers experienced detention time on approximately 1 in every 10 stops for an average duration of ; 1.4 hours. This represents the length of time the driver was detained beyond 2 hours; thus, he/she was ; loading/unloading at that delivery location for 3.4 hours in total. Medium-sized carriers (51–500 power units) had ; similar average detention times as large carriers (more than 500 power units); however, they experienced driver ; detention about twice as often as large carriers. For example, 19 percent of stops made by medium-sized carriers ; were accompanied by detention time compared to 9 percent of stops made by large carriers. The calculation of odds ; ratios (ORs) provided similar results for medium-sized carriers when compared to large carriers. The odds of a ; driver being detained were 2.17 times greater for medium-sized carriers than for large carriers. Operation type did ; not have much impact on the average length of detention time; however, operation type influenced how frequently ; drivers experienced detention time, with for-hire truck load (TL) carriers experiencing detention time more than ; twice as frequently as for-hire less-than-truckload (LTL) carriers and four times more often than private carriers. ; The OR analysis also indicated that for-hire TL carriers were worse off than for-hire LTL or private carriers. The ; odds of a driver being detained were nearly 5 times greater for for-hire TL carriers than for private carriers and ; 2.6 times greater than for for-hire LTL carriers. The odds of a driver being detained were 6.3 and 1.9 times greater ; for temperature controlled freight carriers than for dry bulk carriers, and liquid bulk/tank freight carriers, ; respectively.
