Traffic flow
-
Harmonization of speeds on the individual traffic lanes of the motorway
-
Warning of fog, rain, etc. (i.e. of weather-related hazards)
-
Warning of traffic jams
The following systems are available for traffic control
-
Road-control installation
-
Network-control installation
-
Motorway junction-control installation
The Road-control installations manage the traffic on continuous routes by displaying speed limits and warning notes. The Network-control installations by means of variable sign posts, accomplish the required diversion of traffic in a regionally limited motorway network (road network). Depending on traffic intensity, junction-control installations assign individual lanes in a motorway junction to different traffic streams. This way, fluctuations of the traffic volume in the course of the day can be harmonised.
Elements of traffic control installations are:
-
Traffic processor control centre / sub-center
-
Road station
-
Traffic-data detection
-
Variable traffic-sign installation
-
Detection of environmental data
-
Detection of operational data
