According to the “Report 2010” of the Association des Constructeurs Européens de Motocycles (European motorcycle manufacturers' association), the number of motorcycles throughout the European Union rose from 16 million to more than 22 million between 2001 and 2008. Taking all two-wheeled motor vehicles into account, in 2008 approximately 33 million vehicles were registered. At the same time, motorcycles are by far the most dangerous means of transport. Two groups (children and elderly people) are especially vulnerable due to their weakness against impact, reflexes and reaction to risk, resistance to the generated forces, etc. According to the latest accidents data from the European Community database on road accidents (CARE), more than 110 children under 14 years old who were passengers on PTW's were killed on the roads of the Community between 1991 and 2000.

Worldwide, 1.2 million people die in road crashes yearly; 43,000 in Europe alone. This implies a cost to European society of approximately 160 billion euros, and takes up 10% of all healthcare resources. To reduce these rates, safety technologies have been developed which help to minimize the severity of injuries to vehicle occupants. However, studies have shown that most deaths due to road accidents occur in the time between the accident and the arrival of medical care. Therefore, a fast and efficient rescue operation would significantly increase the injured person's probability of survival. The aim of this project was to define the On-Board Unit (OBU) hardware and software installed in all modern vehicles which could request medical and technical support after a road accident. This device, based on the information from the vehicle sensors, automatically decides whether the car has suffered a road accident or not, the severity of the accident and the kind of accident (impact area).
