Abstract

A simulator study was carried out to investigate the effects of sign change patterns in a fog signalling system on driving speed choice. There were four levels of sign change, which consisted of an increasing level of "filtering" the sequence of signs that indicated a speed limit. This is: filling gaps in a sequence, keeping a sequence consistent, or making an introduction. This level of "filtering" was between subjects. Within subject system functioning (with or without system) and sight distance (sight distance 180 m, 105 m or 50 m, and repeatedly presented) were varied. It was found that system availability and sight distance influenced driving speed. Subjects drove slower with the system and with less sight distance. The more "filtering" the lower driving speed was found. However, this was an effect of the restrictive limits by higher levels of "filtering". It was also found that the effect of system availability decreased when the driving speed chosen without system was already close to the limit indicated by the system. In a regression analysis it was possible to model the speed choice with the system as a function of the speed choice without. It appeared that the deviation between vehicles decreased as a function of system availability. (A)
