Road Works Warning (RWW)
Return to the Services

Road Works Warning (RWW)

 

Road Works Warning provides in-vehicle information and warnings about road works, changes to the road layout, and applicable driving regulations. Road works usually affect the road layout and driving regulations. Despite dedicated signage prior to road work zones, such changed conditions frequently come as a surprise to vehicle drivers. This may lead to increased risk and sometimes even accidents, both for road users and workers. The objective of the services is to achieve more attentive driving while approaching and passing a work zone by providing in-vehicle information and warnings about road works, changes to the road layout and applicable driving regulations.

Participating actors in Road Works Warning include vehicle drivers who receive road works location information on the in-vehicle display or smartphone, road operator who may signal the existence of a road works location, and service providers who disseminate the road works location information to vehicle drivers.

 

The main objective of Road Works Warning is to improve road safety. The service aims to reduce the number of collisions with safety-objects near road works and to increase the safety of road work workers.

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 Road Works Warning service.

Architecture
ITS-G5

In case of ITS-G5 communication technology, a Roadside ITS station or a Roadworks vehicle shall send Cooperative Awareness Messages (CAM) periodically, while the service shall send Decentralized Environmental Notification Messages (DENM) to vehicles near and/or inside the roadworks relevance area. A visual interface in personal information users’ devices (smartphones, tablets) should show the information to the driver.

Cellular

In case of cellular communications a Traffic Management System sends a road work update directly to the back-office system of the Service Provider. The Service Provider forwards this update to the back-office system of a Communication Provider, in order to disseminate the message to personal information devices. The difference in information flow in the case of ITS-G5 communications is that the Communication Provider forwards the road work update to Roadside Units (RSUs) in the vicinity to disseminate the message to OBUs that have subscribed to the service.

Return to the Services

Within the C-MobILE project the Road Works Warning service is implemented in all eight Deployment Sites: Barcelona, Bilbao, Bordeaux, Copenhagen, Newcastle, North Brabant, 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 Road Works Warning service is implemented using cellular communication technology. This service covers the entire city, including its main access roads, and informs road users about both short and long-term roadworks. Applus IDIADA is the service provider receiving the information from the mobility databases of the City Council, the Servei Català de Trànsit and RACC, and providing that to the road users through an App.

Bilbao

In Bilbao the Road Works Warning service is implemented using cellular communication technology. The service is available in the urban road network. CEIT is the service provider cooperating with Bilbao OpenData Platform and Traffic Management Centre for road works data provisioning. NeoGLS is the App provider for this service providing users with real time information.

Bordeaux
In Bordeaux the Road Works Warning service is implemented using both cellular and ITS-G5 communication technologies. The roadworks information comes from both the “Bison Futé” database named “TIPI” (providing roadworks information on highways and inter-urban roads) and the Bordeaux Métropole OpenData (providing roadworks information in the urban area). The service provider for RWW is NeoGLS and the service is available through the App “CTD – Connected Mobility”.

Copenhagen

In Copenhagen the Road Works Warning service is implemented using cellular communication technology. The service covers the entire city road network. Road works data are provided by road works contractors and operators to the city’s open database, primarily for the purpose of authority approval. From this database information is acquired and published by the local Geo-Messaging server according to the appropriate standards to allow service providers and App developers to provide the information to their users.

Newcastle
In Newcastle the Road Works Warning service is implemented using cellular communication technology. The data comes from a database of events managed and operated by the Tyne and Wear UTMC. This data is converted to DENM messaging by Zircon and Siemens and delivered in real time for users of the CTD App developed by NeoGLS. This service is available across the Tyne and Wear region, and also on highways England roads across the whole north east region of England.
