Motorcycle Approaching Indication (MAI)

Motorcycle Approaching Indication (MAI)

Motorcycle Approaching Indication (including other Vulnerable Road Users) warns the driver of a vehicle that a motorcycle is approaching/ passing (the scope can be extended to cover Vulnerable Road Users, such as pedestrians, cyclists, or moped riders). The motorcycle could be approaching from behind or crossing at an intersection. The service assists the driver with blind spots.

Participating actors in Motorcycle Approaching Indication include vehicle drivers, who receive awareness warning about the two-wheelers in proximity on the vehicle, two-wheeler riders, who receive awareness warning about the other vehicles in proximity on the vehicle, and service providers, who disseminate the awareness warning information to vehicle drivers.

The objective of Motorcycle Approaching Indication is to provide timely in-car driving assistance information on an approaching motorized or powered two-wheeler 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 Motorcycle Approaching Indication service.

Architecture

ITS-G5

In case of ITS-G5 communication technologies and for the case of the approaching two-wheeler warning, the On-Board Unit is periodically sending CAMs to near vehicles. Therefore, the On-Board Unit provides location data to calculate a possible crossing. In case of Vehicle-to-Infrastructure communication the On-Board Unit is sending its location to the Roadside Unit as well. If a possible collision is detected, the Roadside Unit will warn near vehicles by sending DENMs to the On-Board Units.

Cellular

In case of cellular communication technologies the Personal Information Devices send periodically CAMs to the Service Provider Back Office once they enter a specific area. If the Service Provider Back Office detects colliding trajectories, it uses the Communication Provider Back Office to send a DENM as GeoMessage to the related Personal Information Devices.

Suppliers

Suppliers of components and solutions for the Motorcycle Approaching Indication service include research institutes, such as CTAG, as well as private companies, such as NeoGLS, IDIADA, Dynniq, and Swarco.

Within the C-MobILE project the Motorcycle Approaching Indication service is implemented in three Deployment Sites: Barcelona, Bordeaux, and Vigo.

Barcelona

In Barcelona the Motorcycle Approaching Indication service is implemented using cellular communication technology. This service is active in over 100 intersections around the city. Applus IDIADA is the service provider receiving location and speed information from motorcycles riding through a specific, dangerous intersection, and informing other drivers about their presence via an App.

Bordeaux

In Bordeaux the Motorcycle Approaching Indication service is implemented using both cellular and ITS-G5 communication technologies. This service uses vehicle to vehicle communication to trigger alerts when a motorcycle is approaching a potentially dangerous intersection. The service provider for MAI is NeoGLS and the service is available through the App “CTD – Connected Mobility”.

Vigo

In Vigo the Motorcycle Approaching Indication service is implemented using cellular communication technology. This service provides real time information about the presence and position of nearby motorcycles to the drivers using the local App.
