Lead Developer

CERTUS supplies all types of traffic control equipment like barriers, traffic lights, lane signage, bill boards and sensors. A combination of these components make it possible to guide trucks through a facility, following dedicated process steps. This ensures a efficient traffic flow, even in case of queuing. Should a large amount of trucks be counted at a specific process point, those trucks can be queued at a previous process point by holding barriers closed. All equipment is effectively integrated through the Port Automation & Security System (PASS), thereby making it possible to monitor the status and control any component remotely.
