Crash avoidance and driver assistance technologies – are they used?

Crash avoidance systems have the potential to reduce fatal crashes, but they must be turned on to be effective. However, previous research has shown that lane departure warning systems are turned off by drivers more frequently than other crash avoidance systems. In this study 983 observations of vehicles being serviced were made at 14 dealerships in the Washington, DC, metro area. In about 51% of the vehicles, the lane departure warning system was turned on. In comparison, the front crash prevention system was turned on in 93% of the vehicles. A survey of the vehicle owners asked their opinion of the lane maintenance systems. For those drivers whose systems were turned off, a higher percentage reported that they found the lane departure warnings distracting (37%), the system issued a lot of unnecessary warnings (43%), and the warning beeps were annoying (42%). An analysis of likelihood of lane maintenance system use by vehicle manufacturer, lane maintenance intervention level, and total vehicle mileage is included. In addition, ease of access in turning off systems is discussed. It is suggested that lane maintenance systems with tactile rather than auditory warnings, increased degree of lane maintenance intervention, and menu tasks rather than physical buttons to disable the system would increase the likelihood of drivers using the systems.
