California is in its third year of an accelerated program to find out why drivers enter the wrong end of freeway off-ramps. A portable surveillance unit counts each vehicle that enters an off-ramp an off-ramp in the wrong direction and verifies this action by taking a single photograph. The results are sometimes surprising. Considerable wrong-way activity has been recorded at ramps that had given no prior indication of this problem. It has been encouraging to find that many wrong-way movements can be prevented by simple signing and delineation changes. /HRIS/
