Summary
This study, conducted by the University of Michigan Transportation Research Institute and Science Applications International Corporation for the Federal Highway Administration (FHWA), addresses the potential mandatory use of electronic recorders (ERs) in commercial motor vehicles. The research was initiated in response to a 1995 petition by the Insurance Institute for Highway Safety and other organizations, which argued that mandating ERs would improve driver compliance with hours-of-service (HOS) regulations. The primary objectives were to assess the current extent of ER usage within the motor carrier industry, evaluate the costs and benefits of using ERs for HOS compliance, and gauge industry attitudes toward making such technology mandatory. The methodology involved a survey of trucking and bus industry associations and a random sample of carriers from an FHWA census file. Five associations participated, including the National Private Truck Council and the Owner Operator Independent Drivers Association. Researchers selected a sample of approximately 6,500 carriers, categorized by fleet size into small (less than 9 trucks), medium (9–100 trucks), and large (more than 100 trucks) groups. Three versions of a questionnaire were developed for for-hire firms, owner-operators, and bus fleets to collect data on ER usage, HOS recording methods, and the perceived impact of mandatory ER use. Approximately 10,000 questionnaires were mailed in January 1997, yielding about 1,200 responses, resulting in an overall response rate of 11.8 percent. The findings indicate that ER adoption is strongly correlated with fleet size. Of the 1,200 responding fleets, 175 reported using ERs, but only 37 used them as the primary method for HOS compliance. Usage was concentrated among large truck fleets and National Private Truck Council members; no for-hire fleets or owner-operators used ERs as their primary HOS method, and only one bus fleet did. Small fleets, which constitute approximately 90 percent of regulated carriers, rarely adopted the technology. Financial data suggested an acquisition and installation cost of approximately $2,000 per vehicle, with annual operating and maintenance costs around $200. While electronic logs saved drivers about 20 minutes per day and fleet managers 20 minutes per driver per month compared to paper logs, carriers without ERs overwhelmingly cited excessive cost as the reason for non-adoption. The study concludes that there is no evidence that ERs are cost-effective for small fleets, which make up the majority of the industry. The overwhelming view among fleets of all sizes was that mandatory ER use would impose excessive expenditures with minimal benefits. The authors note that ERs are only useful for controlling HOS to the extent that management actively reviews and acts on the data. Consequently, the study found no significant operational benefits to mandating ERs for HOS recording and did not address the relationship between ERs, HOS compliance, and safety, leaving those complex relationships for other research programs.
Key finding
Only 37 out of 1,200 responding fleets used electronic recorders as their primary method for hours-of-service compliance, and carriers overwhelmingly viewed mandatory adoption as excessively costly with minimal benefits.
