Telematics systems can provide notifications in case of emergencies, also known as Mayday services. Emergency notifications can be initiated manually, e.g. by the driver pushing a panic button, or automatically, e.g. triggered by airbag, front impact, side impact, and rollover sensors. Vehicle position and the type of damage are transmitted to the service centre. After receiving and verifying the emergency message, the operator at the service centre initiates appropriate measures in co-operation with relevant external organisations, such as police, fire brigades, or medical services. Access to additional information can be provided to the emergency service, e.g. driver-specific information concerning medical data and name of doctor, or data on the nature and condition of hazardous goods. Emergency management systems can reduce rescue times by as much as 30 per cent.
