Emergency Brake Light (EBL)
The objective of Emergency Brake Light is to warn all following vehicles of a sudden slowdown of the traffic so limiting the risk of longitudinal collision.
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 Brake Light service.
In Bordeaux the Emergency Brake Light service is implemented using ITS-G5 technology. It works by sending hard-brake warning from vehicle to vehicle. In addition, 11 RSUs have been deployed being able to receive this alert and forward it to other users not equipped with an OBU, but using the local App on their smart devices connected via cellular communication. The service provider of the EBL service is NeoGLS and the service is available through the App “CTD – Connected Mobility”.
In Vigo the Emergency Brake Light service is implemented to alert drivers using local App on hard-braking actions executed by preceding vehicles. It is implemented as proof of concept in a simulated environment.
