Safe-haven Presence DetectionThe Safe-haven Presence Detection (VAD in Dutch) system detects de presence of one or more vehicles in the safe-haven area. Presence detection of vehicles is realized by means of inductive loops in the road surface and is reported to a central system for further action. The VAD roadside systems are used at rush-hour lanes on the motorways where the emergency lane is temporarily used as a normal traffic lane. Using the emergency lane as a normal traffic lane involves offering safe-havens to the motorists in case of a vehicle break-down or other emergency. Therefore when using rush-hour lanes safe-havens are provided on regular distances, which are (real-time) monitored with the VAD roadside systems and a central system. The VAD roadside system consists of a powerful processor platform called the TrafficBox and a detection module. The communication interface between the VAD roadside system and the central system is based on the Industrial Ethernet/Ethernet IP protocol, which consists of Ethernet, TCP/IP and CIP. The VAD application can be completely configured and monitored remotely. Naturally the VAD roadside system complies with all environmental requirements for outdoor usage. |
