Increased Safety and Traffic Flow at the Level of Cheaper Roadworks: The ASF Success on the A7 Motorway

The A7 motorway is the North-South road that follows the Rhone Valley from Lyon to Marseille in France. The motorway is a major regional and European economic artery. The total absence of an alternative replacement route demands extreme care in maintaining the level of availability. Along the section between Valence and Orange, the road bears average daily traffic of 76,000 vehicles per day, with 18% heavy goods vehicles (HGV). Summer traffic regularly exceeds 150,000 vehicles per day. Every year, the period during which traffic conditions allow for closing off lanes for road work grows increasingly smaller. This road section started operations between 1967 and 1968. It is now nearly 40 years old and requires continual heavy renovation work. Road geometry was initially composed of 3 3.50-meter lanes open to traffic and a 3-meter wide emergency lane. The road section was recently equipped with a central median with steel safety guard rails.
