END Turned-Down ENDs: How the United Kingdom Accomplished It

This presentation looks at how the U.K. government roads body, the Highways Agency (HA), moved from the use of barrier terminal ramped ends to the use of European Normative (EN) 1317-compliant P4 terminals on roads with a posted speed limit of 50 mph or greater. To date, there are more than 6,000 P4 terminals installed in the U.K., supplied by a number of manufacturers.
