Emergency Vehicle Warning (EVW)

Emergency Vehicle Warning (EVW)

Emergency Vehicle Warning (EVW)

Emergency Vehicle Warning provides in-vehicle information and warnings about approaching emergency vehicles. Vehicles can identify themselves and inform other vehicles in the vicinity about their position, direction and speed even when the siren and light bar of the emergency vehicle may not be audible or visible.

Participating actors in Emergency Vehicle Warning are vehicle drivers who receive warnings and/or guidance on the in-vehicle display when an emergency vehicle is approaching, emergency vehicle drivers who disseminate the emergency vehicle location information, road operator who may signal the existence of an emergency vehicle locations, and service providers who disseminate the emergency vehicle location information.

The objective of Emergency Vehicle Warning is to sooner indicate an emergency vehicle is approaching and to timely give way to the emergency vehicles.

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 Emergency Vehicle Warning service.

Architecture

ITS-G5

In case of ITS-G5 communications, emergency vehicle disseminate CAM messages. Broadcasted messages are received by nearby equipped stations (vehicles and Roadside Units) in the communication range of the sending emergency vehicle. Once received, the vehicles determine if the event is relevant for them and show a warning to the driver accordingly. In the case of the Roadside Units (RSU), they need to convert the CAM message into a DENM message and disseminate it down to the vehicles again in the wanted relevance zone.

Cellular

In case of cellular communications, the Personal Information Device (PID) of the emergency vehicle sends the CAM message to service providers. Service providers forward the message communication providers, in order to initiate the dissemination of the message to the other vehicles (PIDs).

Suppliers

Suppliers of components and solutions for Emergency Vehicle Warning service include research institutes, such as CEIT, CERTH-HIT, and CTAG, as well as private companies, such as Dynniq, IDIADA, NeoGLS, Kapsch, Technolution, Traffic Technique, and Swarco.

Within the C-MobILE project the Emergency Vehicle Warning service is implemented in five Deployment Sites: Barcelona, Bordeaux, North Brabant, Thessaloniki, and Vigo.

Barcelona

In Barcelona the Emergency Vehicle Warning service is implemented using cellular communication technology. This service is currently dedicated to the local firefighters and covers the whole city area. Applus IDIADA is the service provider receiving emergency data from the emergencies management centre of the City Council and providing through an App the drivers with the information about an approaching firefighters’ vehicle in emergency status.

Bordeaux

In Bordeaux the Emergency Vehicle Warning service is implemented using ITS-G5 communication technology. Emergency vehicles equipped with an on-board unit (OBU) broadcast their emergency status to surrounding OBUs and roadside units (RSUs), triggering an alert message with a request to free the passage. The information is also forwarded by the RSUs and made available to other users not equipped with an OBU, but using the local App on their smart devices connected via cellular communication. The service provider for EVW is NeoGLS and the service is available through the App “CTD – Connected Mobility”.

North Brabant

In North Brabant the Emergency Vehicle Warning service is implemented using hybrid cellular and ITS-G5 communication technologies. This service is active with the firefighters, police and ambulances in Helmond and covers the main roads.

Thessaloniki

In Thessaloniki the Emergency Vehicle Warning service is implemented as proof of concept using cellular communication technology. The the service provider, the Hellenic Institute of Transport (CERTH-HIT), uses its own vehicles for testing purposes providing information to other drivers through the CERTH-HIT App (cmobile.imet.gr).

Vigo

In Vigo the Emergency Vehicle Warning service is implemented using cellular communication technology. This service provides in real time information related to the presence and position of a nearby emergency vehicle to the other drivers using the local App.
