Traveling construction sites come as a surprise to many drivers if they rely primarily on their navigation system, Google Maps or Apple Maps. This is set to change with a pilot project by the North Rhine-Westphalia State Transport Center and Vodafone. The mobile phone provider helps to network the traveling construction sites. The barrier trailers at a traveling construction site will be equipped with 5G transmitters. This provides the location information for the map services in real time.
The technology used for this is based on a V2X (Vehicle to everything) platform called STEP (Safer Transport for Europe Platform), which Vodafone presented a year ago. The system, described by the company as open to providers, is aimed at authorities and companies that transmit safety and traffic information directly to map apps on smartphones and to in-vehicle navigation systems. STEP, in turn, is based on the open network protocol Message Queuing Telemetry Transport (MQTT) for communication between machines (M2M).
More security through the Internet of Things
Vodafone’s head of innovation Michael Reinartz expresses the principle like this: “If roadblock trailers transmit in the Internet of Things, then it increases safety on our roads.” It is also conceivable to extend this technology to the ends of traffic jams so that their exact position can be communicated to other road users at an early stage. If we think even further into the future, bus and truck drivers in networked traffic could be made aware of cyclists and pedestrians in their blind spots.
The NRW State Transport Center is responsible for “intelligent, digitalized and networked mobility” in the state. Among other things, it wants to centrally record, monitor and network 5,500 traffic lights in the country. AI regulates the flow of traffic at an intersection in Hamm. The headquarters also takes care of the coordination of construction sites.
