Summary:
This study addresses the concern of low comprehension and compliance at three lane roundabouts. The objectives of the study were to identify signing and marking strategies that result in higher levels of comprehension and compliance in lane selection on the approach to roundabouts and to examine the effects of these strategies on lane use after an approach lane has been selected. It was found that overhead advance navigation signage is more favorable for roundabouts with three entering lanes and that navigation signs at least supplement any other overhead lane restriction signing. One possible way to keep drivers in their lanes was found to be the turbo roundabout, which has been used in several European countries. The turbo roundabout uses raised mountable curbs between lanes to discourage lane changes. This design also encourages drivers to move into the appropriate lane before entering the roundabout. Another possibility for keeping drivers from changing lanes once they are guided to appropriate lanes includes installing enhanced lane markings and other forms of channeling such as rumble strips.
