Abstract

The development of criteria for the installation of central reserve safety fence on 60 and 70 mph all purpose dual carriageways is discussed. Personal injury accidents were examined on over 350 km of all purpose dual carriageways in England, of which 142 km have a safety fence. Safety fences were primarily intended to reduce accidents where a vehicle crosses into the opposing carriageway; however because of possible effects on general safety, all types of accidents were considered. The report presents tabulations of accidents by frequency, severity and by type of interaction with the central reserve. Accident frequencies are further considered in relation to traffic flow and site characteristics, the latter including road geometry and layout.
