EFFECT OF CLEAR VISION RIGHT-OF-WAY ON TRAFFIC ACCIDENTS AT URBAN AND RURAL SIGNALIZED INTERSECTIONS

The results of this research can be summarized as follows: 1. There was a significantly higher injury accident rate at four-legged signalized intersections (both urban and rural), and urban Tee signalized intersections with poor vision than at those with clear vision. 2. There was a significantly higher property damage accident rate at four-legged signalized intersections (both urban and rural), and urban Tee signalized intersections with poor vision than at those with clear vision. 3. There was a significantly higher accident rate at four-legged signalized intersections (both urban and rural), and urban Tee signalized intersections with poor vision than at those with clear vision. It is felt that the possibility of providing appropriate clear vision right-of-way on state highway routes should be carefully considered in initial purchase, that most existing clear vision right-of-way be retained and that acquisition of clear-vision areas at many intersections in growing areas be acquired before development makes it difficult or impossible. /Author/
