Abstract:This Final Report describes the process and product from the project, Onboard Monitoring and Reporting for Commercial Motor Vehicle Safety (OBMS), in which a prototypical suite of hardware and software on a class 8 truck was developed and
tested.
The OBMS suite allows for online measurement of a set of driving characteristics which are indicators of unsafe driving behavior. These characteristics included speed, following distance, lane-keeping performance, safety belt use, and the use of turn signals. Feedback could be provided to the drivers, either directly via real-time feedback or through carrier management, to allow drivers to significantly improve their safety performance. For example, if a driver received a report that he/she is not using his/her turn signals during lane changes, that driver can then be monitored during a follow-up period to determine if the feedback had corrected the deficiency. Commercial fleets would pioneer this concept because they have the resources and organizational structure to provide feedback and training to professional drivers. This concept differs from commercial onboard devices in that it is an ensemble set of instruments (not one or a few warning devices) with a safety focus and different feedback modalities. It is comprehensive in that it addresses crash causes and provides “corrective” feedback in real-time and/or post trip feedback, depending on the particular subsystem(s) which are activated. In essence, the objective is to improve driver safety behavior. Thus, it does not explicitly address fleet management or other non-safety operations (for example, vehicle location).
A systems engineering process was applied to this research, resulting in a prototypical OBMS hardware suite and a plan to follow-up this effort with an FOT. This project is the result of a Federal Motor Carrier Safety Administration’s Cooperative Agreement with the California Department of Transportation (Caltrans). It was undertaken by the California Partners for Advanced Transit and Highways (PATH) program, with assistance from the California Center for Innovative
Transportation (CCIT) and a subcontractor, Advanced Systems Engineering Consulting
