This paper presents a study which compares the effects of providing drivers with information about their speed errors at curves and at intersections, when they repeatedly drove a predetermined route under simulated traffic conditions. On each of the circuits subjects encountered a number of supported and unsupported scenarios in curves and at intersections. During the drive the actual performance of the subjects in these scenarios was compared to a criterion set by rules implemented in a support module. The effects of different types of support on the performance of drivers in curves are discussed. Immediate auditory feedback after an error was found to reduce the incidence and size of speed errors more than any of the other types of support evaluated. The effects of feedback generalized to situations where support had not been given. (A)
