Abstract:The number of both crashes and fatalities involving large trucks has steadily been decreasing due to improved safety features (seat belt use, air bags, better brakes, etc.). Many safety professionals contend that to continue the improvement trend, it will be necessary to utilize “active” safety systems (e.g., adaptive cruise control, roll stability, collision warning, etc.). The passive systems are effective at reducing the severity and consequences of accidents; whereas the goal of active systems is to avoid accidents before they occur. Some of the “driver assistance” systems only provide a warning to the driver when an incident occurs while more advanced systems also record the occurrences or even provide active vehicle control (e.g., steering, braking, etc.). The proposed research specifically addresses the human factors issues associated with devices that are intended to reduce the potential of heavy truck accidents that are associated with running off the road, inadvertently moving into the adjacent lane and side collisions. Iteris, a manufacturer of a lane departure detection system states that 40% of all traffic fatalities are related to unintentional lane departure. An economic study determined that unintended land departure account for approximately 16% of total maneuver related accident costs. These personal and financial costs affect both the trucking industry and society as a whole. The Large Truck Crash Causation Study Interim Report published by the Federal Motor Carrier Safety Administration indicates that the frequency, severity and costs of these accidents are predominantly associated with human error rather than road conditions or equipment malfunction. Pomerleau et al. (1999) found that 76% of the accidents occurred on straight roads and 73% occurred when the weather was clear. The causes of lane departure and side collision accidents are most often attributed to one or a combination of three factors: fatigue; inattention; or driver distraction. Although fatigue and inattention have received the most attention, driver distraction associated with in-vehicle information systems in becoming an increasingly important issue for commercial trucking operations
