The idea behind eCall is that in the event of a car accident, technology in the car automatically dials the emergency services number 112 via the mobile telecommunications networks and provides data on the vehicle location and vehicle type to the emergency services. The emergency services can then rapidly respond and arrive at the scene of an accident to deliver medical assistance more quickly than would otherwise be the case, possibly saving lives and reducing the severity of serious injuries. Traffic management authorities can respond more quickly to accidents on busy roads to mitigate the secondary effects of traffic congestion, fuel consumption and carbon emissions.
