Signal Violation Warning (SVW)
The objective of Signal Violation Warning is to provide timely in-vehicle driving assistance information on a signal violation downstream of the current position and in the driving direction of the vehicle.
Taking into account various stakeholders’ views, a list of business model blueprints that address current or future challenges of urban areas, together with their operating and value-capture scenarios depicting the inner-workings of the business models, and the exchange of costs-benefits among stakeholders, have been created for the Signal Violation Warning service.
In Barcelona the Signal Violation Warning service is implemented using cellular communication technology. This service is combined with the GLOSA service, at the same intersections. Applus IDIADA is the service provider working with traffic light information from the traffic management centre of the City Council and warning drivers in case they are likely to drive through a red light, depending on their speed and location.
In Bordeaux the Signal Violation Warning service is implemented in combination with the GLOSA service using both cellular and ITS-G5 communication technologies. A total of 588 intersections are configured with cellular communications in Bordeaux and its surroundings. Gertrude provides the Signal Phase and Timing (SPaT) information in real time. In addition 11 ITS-G5 RSUs deployed in the city centre broadcast both MAP and SPaT information at nearby intersections. The service provider for GLOSA is NeoGLS and the service is available through the App “CTD – Connected Mobility”.
In North Brabant the Signal Violation Warning service is based on hybrid cellular and ITS-G5 communication technologies. This service is available in Helmond in combination with with the GLOSA service.
In Thessaloniki the Signal Violation Warning service is based on cellular communication technology. The service provider, the Hellenic Institute of Transport (CERTH-HIT), cooperates with local traffic lights operators (Traffic Technique and Swarco Hellas) for information exchange and provision of information to drivers through the CERTH-HIT App (cmobile.imet.gr).
In Vigo the Signal Violation Warning service is based on cellular communication technology. This service provides information related to Signal Phase and Timing (SPaT) of 95 signalised intersections in the city of Vigo via CTAG GeoServer. Drivers using the local App are alerted if a traffic light violation is about to happen at the headed intersection.
