A STUDY OF ACCIDENT INVESTIGATION SITES ON THE GULF FREEWAY

The degree of freeway congestion and delay caused by an accident depends on the length of time that the accident vehicles block a lane and are visible to other freeway motorists. To reduce the effects of accidents, the investigation by policemen should be made at a location not visible to freeway motorists. The report discusses the use of specially designed accident investigation sites which are located in areas adjecent to the Gulf Freeway in Houston but concealed from freeway motorists. Usage of the sites reduces delay to freeway motorists and frequency of secondary accidents. To improve operation on other freeways, accident investigation sites should be installed.
