The ITS goal of reducing accidents is challenging indeed. Although driver attention and perception errors are a major cause of accidents, on an individual basis drivers are remarkably reliable. The risk of a lateral collision, for example, is estimated at once every 60 years for a given driver. To reduce such a low risk further will be no mean feat. The task of reducing accidents through its is also challenging because of severe driver limits in information processing capacity. As the number of ITS systems increases, drivers may be inundated with information and warnings, potentially overloading, rather than aiding them. This will be particularly a problem where its systems are optional extras, and are not integrated in an "intelligent" driver interface which prioritizes information and warning depending on the driver's task. Safety evaluations of each new device, as well as their impact in the context of other such devices, will need to be undertaken to determine the effects of this change in driver task on safety. |
