In-Vehicle Signage (IVS)

 

In-Vehicle Signage shows both static and dynamic information of road signs inside the vehicle. The service is meant to inform drivers via in-vehicle information systems on static and dynamic road signs as indicated on physical road signs and on additional digital displays along the road. Both advisory and mandatory road signs are in scope of the service.

Participating actors in In-Vehicle Signage include vehicle drivers, who receive information from the in-vehicle display or smartphones, road operators, who provide info on dynamic road signage, service providers, who disseminate related information, warnings and/ or guidance to vehicle drivers, and end users as trip planners may use information, and expected delays caused by these, to optimize their trip planning.

 

The objective of In-Vehicle Signage is to improve traffic safety via additional means to provide drivers with in-vehicle signage information.

Business models

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 In-Vehicle Signage service.

Architecture
ITS-G5

In case of ITS-G5 communication technologies dynamic/ static traffic signs information are sent from the Traffic Management Center to the Data Provider Back Office (or, alternatively, directly to the Service Provider Back Office). In order to disseminate the traffic signs information, the GeoMessaging is used, therefore the Communication Provider Back Office receives the data from the Service Provider Back Office and proceeds with the dissemination to the cooperative vehicles. The appropriate Roadside Unit (covering the desired dissemination region) receives the information to be broadcasted to the cooperative vehicles.

Cellular

In case of cellular communication technologies dynamic/ static traffic signs information are sent from the Traffic Management Center to the Data Provider Back Office (or, alternatively, directly to the Service Provider Back Office). In order to disseminate the traffic signs information, the GeoMessaging is used, therefore the Communication Provider Back Office receives the data from the Service Provider Back Office and proceeds with the dissemination to the connected vehicles.

Suppliers

Suppliers of components and solutions for the In-Vehicle Signage service include research institutes, such as CERTH-HIT, CTAG, as well as private companies, such as NeoGLS, IDIADA, Dynniq, Traffic Technique and Swarco.

Return to the Services

Within the C-MobILE project the In-Vehicle Signage service is implemented in five Deployment Sites: Barcelona, Bordeaux, Newcastle, Thessaloniki, and Vigo.

Invisible
In Bordeaux the Green Priority service is implemented on a defined area containing five successive intersections approaching an hospital. The service provider is NeoGLS. In collaboration with Gertrude, when an RSU detects the presence of an equipped emergency vehicle, it forwards a priority request to the Traffic Light Controller, which will pass the lights to green at this traffic light, but also on the traffic lights ahead, to clear the way for the emergency vehicle until he reaches the hospital.
Barcelona

In Barcelona the In-Vehicle Signage service is implemented using cellular communication technology. This service provides information about speed limits in the whole city as well as on the main access roads (which is also displayed on the traffic panels). Applus IDIADA is the service provider receiving information from the mobility databases of both the City Council and the Servei Català de Trànsit’s and providing it to the road users through an App.

Bordeaux

In Bordeaux the IVS service is implemented using both cellular and ITS-G5 communication technologies. This service is deployed in 3 different zones :

  • The city center, where users are informed about the 30 km/h speed limit in schools’ proximity
  • The ring road, where users are informed about travel times and other information about the traffic status
  • The A63 highway, where traffic information is also available on varabile message sign (VMS) installed on gantries

The service provider for IVS is NeoGLS and the service is available through the Appl “CTD – Connected Mobility”.

Copenhagen
In Copenhagen the GLOSA service is implemented using cellular communication technology. The service provides speed advice for users so to be able to catch the green light at intersections ahead. Time-to-green and Time-to-red information is sourced in the Traffic Light Controllers and published by the local geo-messaging server in the appropriate messaging and communication standards to allow service providers and App developers to provide the information to their users. In Copenhagen, this same service is specifically tailored for optimal use by cyclists. Because cycling traffic is a more flexible mode of transport than motorized vehicles, making it easier for each cyclist to adjust their own speed and, unlike cars, less dependent on the speed of other road users in front and behind, the GLOSA service works better for cyclists especially with a lower saturation levels of the service among users.

Newcastle
In Newcastle the IVS service delivers speed limit information using cellular communication technology. The data relates to the same route north out of the city centre as the GLOSA and green priority, a route on which there are multiple speed limit changes. However, the IVS delivers IVI messages using Zircon and Siemens technology, which is delivered for users of the CTD App developed by NeoGLS.

Thessaloniki

In Thessaloniki IVS is provided as static and dynamic information to drivers. The service provider, the Hellenic Institute of Transport (CERTH-HIT), uses information from its digital maps and information retrieved from the Variable Message Signs (VMS) operated by the Region of Central Macedonia (http://www.pkm.gov.gr/), which is responsible for the operation of the Traffic Management Center. This information is then provided to drivers through the CERTH-HIT App (cmobile.imet.gr).

Vigo

In Vigo the In-Vehicle Signage service is implemented using cellular communication technology. This service provides information displayed on existing Variable Message Signs directly in vehicles in order to optimize the reception of the transmitted message by the conventional sign.

CTAG is the service provider managing traffic information gathered from the Traffic Management Centre of Vigo and the Spanish Traffic Directorate (DGT) and distributing it in real time to drivers through CTAG GeoServer using the local App.
