Safety and efficiency measures for road networks, as recommended by Trafikverket
This report, written by Trafikverket, explains the E4 project from a users point of view. The document contains useful information for similar organisations considering improving safety and efficiency on their road networks. In Trafikverket’s words “A quick and cost effective investment that makes a difference”.
To help make it possible the E4 motorway was extended from 2 lanes to 3 with the installation of Navtech’s ClearWay system to automatically detect incidents and alert operators in the control room.
