HIGHWAY FENCES AS DETERRENTS TO VEHICLE-DEER COLLISIONS

摘要: A survey of highway fencing along I-80 in Centre County, Pennsylvania, showed that 2.26-m (7.41-ft) type 3 modified fence has little value as a deterrent to vehicle-deer collisions; many deer crawl under the planted right-of-way, and gaps underneath provide easy penetration. From December 1974 through March 1976, numbers position were observed from vehicle driven 9.65 km (6 miles) at night. Bimodal patterns abundance found. Deer most numerous spring fall. Of 2577 sightings, 74.5 percent on side 25.5 far fence. Comparisons between control area north highway, where was unmodified, test areas south side, plugged or top five wires removed repaired both, large crossed fully Only six reported killed during 16 months study, no live seen highway. These results, relative previous findings beginning 1967, strongly suggest high traffic volumes prevent venturing onto thus reducing collisions. /Author/
