Equipping a Police Motorcycle with V2X

Approaching Emergency Vehicle Warning

It has now been more than 2 years since we presented the first demonstration of Cooperative Intelligent Transport Systems (C-ITS) for two-wheeler safety as part of the Connected Motorcycle Consortium (CMC). There were some at that time groundbreaking applications demonstrated such as Emergency Electronic Brake Light (EEBL) , Approaching Emergency Vehicle Warning (AEVW), Intersection Movement Assist (IMA), Left Turn Assist (LTA), Road Works Warning (RWW), Do No Pass Warning (DNPW), etc.

One of the most exciting aspects was the successful integration of C-ITS technology into a police motorcycle (Figure 1), specifically for the AEVW use case. The AEVW application addresses a crucial need in situations where an emergency vehicle, such as a police car or ambulance, is approaching, and its exact location is unknown to other road users.

The key here is the reception of Vehicle-to-Everything (V2X) messages by C-ITS-enabled vehicles. These messages serve as the foundation for the AEVW scenario, which plays a vital role in enhancing road safety. As Figure 2 illustrates, when an emergency vehicle broadcasts V2X messages, the AEVW application processes this information, providing timely and precise warning to the drivers and riders in the vicinity. These warning contain data about the emergency vehicle's location and its current movement, enabling other road users to make informed decisions quickly.

The implications of this technology are far-reaching and impactful. In critical moments, when every second counts, drivers and riders will have the information they need to react efficiently and safely. This empowers them to clear a path for the approaching emergency vehicle, reducing the risk of accidents, minimizing response time, and potentially saving lives.

In order to enable the transmission of V2X event messages from a police motorcycle, we initiate the transmission when the blue lights are activated. To carry out this functionality during our real traffic scenario demonstration, we obtained official authorization from the relevant authorities to activate the blue lights.
