  • 2+1 ROADS WITH CABLE BARRIER FOR IMPROVED

    2+1 ROADS WITH CABLE BARRIER FOR IMPROVED TRAFFIC SAFETY. The Swedish interurban network contains approximately 4000 km of 13 m roads carrying more than 25% of the traffic load. The safety is about 15% better than in normal two lane roads. Still, some 100 people die and about 400 are severely injured every year.

  • Cable barrier WikiMili, The Free Encyclopedia

    2+1 road is a specific category of three-lane road, consisting of two lanes in one direction and one lane in the other, alternating every few kilometres, and separated usually with a steel cable barrier. The second lane allows faster-moving traffic to overtake slower vehicles at regular intervals.
