In the Westland region, road hazard at exit points is regarded as a major problem. The region is characterised by roads on which (a) many exits occur and (b) moped traffic drives in two directions on cycle paths situated along one side of the road. This fact explains why 60% of road accident victims amongst cyclists and moped riders are involved in accidents which occur at exit points. This road hazard problem is investigated here. The study consists of two parts: a literature study, and an extensive analysis of over 180 exit-related accidents covering a total of 36 road kilometres in the Westland region. It appears that an important part of road hazard at exit points has to do with moped traffic on cycle paths. Five criteria were drawn up for the application and implementation of exit constructions.It is also recommended to consider other possibilities for solving the problem, including lowering the speed limit on the road or road sections, and the possibility for allowing mopeds to ride on the carriageway. Another recommendation made is to combine various exits to meet at one point. Finally, it is pointed out that uniformity should be aimed for in the solutions and constructions to be applied.
