Samenvatting
This paper details the experimental active traffic management system on the A48 motorway in France. When operational measures alone are not sufficient to cope with congestion, the hard shoulder (emergency lane), widened to 3.5 metres and restructured to allow for traffic use, becomes available for use by emergency service vehicles and authorised scheduled buses. Installations are of a permanent nature (width, colour of road surface, sign and a variety of ITS equipment). Maximum speed on this additional lane, when brought into use for buses, is limited between 20 and 50 km/h, dependingon the speed of the general traffic. For the covering abstract see E134653.
