Road Hazard Warning (RHW)

 

The Road Hazard Warning service aims to inform the drivers in a timely manner of upcoming, and possibly dangerous events and locations. This allows drivers to be better prepared for the upcoming hazards and make necessary adjustments and manoeuvres in advance.

Participating actors in Road Hazard Warning are vehicle drivers who receive hazardous location information on the in-vehicle display, road operators who may signal the existence of a hazardous location, Service Providers who disseminate the hazardous location information to vehicle drivers, and other organizations charged with repair, maintenance and/ or cleaning may act on the hazardous location information.

 

The objective of Road Hazard Warning is to provide timely in-vehicle driving assistance information on hazardous locations downstream of the current position and in the driving direction of the vehicle.

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 Hazard Warning service.

Architecture
ITS-G5

In case of ITS-G5 communications, the information originates at data providers, who could be a Traffic Management system (TMS), but also a data sharing platform when information is crowdsourced by a community as is common for road hazards. Service providers then read this data and transforms it to C-ITS standards, which means encapsulating the information in DENM messages. Service providers push the data to communication providers. A Road Side Unit (RSU) in the relevant area receives the information and broadcasts the messages. These messages will be picked up by On Board Units (OBUs).

Cellular

In case of cellular communications, the information originates at data providers, who could be a Traffic Management system (TMS), but also a data sharing platform when information is crowdsourced by a community as is common for road hazards. Service providers then read this data and transforms it to C-ITS standards, which means encapsulating the information in DENM messages. Service providers push the data to communication providers. The information gets directly forwarded to Personal Information Devices (PIDs) in the relevant area to display to the end-users.

Return to the Services

Within the C-MobILE project the Road Hazard 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 Hazard Warning service is based on cellular communication technology. This service covers the entire city, including its main access roads, providing real-time information about different hazards (such as congestions, accidents, vehicle breakdowns, weather conditions, etc.) and their location. Applus IDIADA is the service provider receiving the information from the mobility databases of the City Council, Servei Català de Trànsit and RACC and providing it to the drivers through an App.

Bilbao

In Bilbao the Road Hazard 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 hazard data provisioning. NeoGLS is the App provider for this service providing users with real time information.

Newcastle
In Newcastle the GLOSA service is implemented via both ITS-G5 and cellular communication technologies. The ITS-G5 service covers 18 signalized intersections on a key route heading north out of the city centre. This new deployment builds on an existing ITS-G5 installations covering 21 intersections in the east of the city. The new deployment is used by Arriva express buses to enable more efficient fleet operation and more reliable journey times. Siemens UK is the service provider in collaboration with Newcastle City Council and Zircon (HMI designer). Siemens UK and Zircon have also designed and implemented a 4G cellular deployment at one intersection on the same route in collaboration with NeoGLS. Newcastle City Council and Siemens are considering to expand this service through the whole route. This service is for users of the cellular bundle (currently NEAS and some private motorists) delivered to the App provided by NeoGLS .
