In order to increase road safety over a pre-defined section, EFKON has developed the Section Control System, which can enforce every speed between entry and exit point.  It monitors a longer stretch of road, thereby encouraging drivers to keep speed moderate and drive smoothly. 

Thus increasing the traffic throughput. Ghost-drivers (driving in the wrong direction on a highway) are also detected. The system can be set up on highway sections, rural roads, and city roads, in tunnels and also for temporary construction sites. Vehicles are classified on entry of the section and an image of the license plate is taken together with a time stamp. On leaving the monitored section, the same is repeated and images are compared in order to determine average section speed. Optionally speed limit information, based on weather conditions and classification can be displayed via VMS (Variable Message Sign) to vehicles so drivers can be notified.

EFKON’s average speed control system (Section Control) consists of one or more entry and exit gates and is capable of operating in speeds up to 250 km/h. The single or dual gantry solution may provide front- or back-shot images and fully works in a Multi Lane Free Flow (MLFF) environment. The system allows prior registered exempt-users (ambulance, fire brigade, etc.) to pass un-enforced. An efficient database may carry such vehicles in a white-list.

The general software and hardware design is based on a unique modular concept which allows easy scalability to cover highways from 2 lanes up to 6 lanes in one direction including hard-shoulder.

Typically the front-end components are installed on a gantry on an open highway. But it also makes sense to install the road side sensors on existing infrastructure like tunnel ceilings or bridges.

 
Workflow:

• At the extry gate each passing vehicle is detected by using optical mehtods
• Speed enforcement camera captures snapshot and characteristics of vehicle
• ANPR module extracts the license plate out of the image
• Traffic event (image, license plate and timestamp) is created and sent to the exit gantry
• At the exit gantry image, license plate, timestamp and classification is recognized
• Matching of traffic events from entry and exit gates is performed
• Depending on vehicle class, calculated average speed is compared with maximum allowed speed
• In case of a violation case is detected, alert is sent to the Back Office
• Back Office requests violation image data from enty and exit gate for further processing
   

Typical Application Environment:

• Monitoring different speed limits
• Harmonization of traffic flow
• Surveillance of closed lanes
• Detection of wrong-way drivers (´ghost cars´)
• Image triggering for vehicles exceeding height limit
• Detection of stolen vehicles
• Traffic surveillance
• Statistical data
