Abstract

The accident detection system for a vehicle circulation path has each vehicle provided with a shock detector (1), used to automatically actuate a radio transmitter (2) if the vehicle is involved in a collision. A number of emergency call stations are positioned at spaced points along the circulation path, each station having a receiver responsive to the distress signal provided by the radio transmitter (2) aboard the vehicle. The station then transmits a call signal to a central control, identifying the call station. A manual control (4) may also be provided aboard each vehicle, to actuate the radio transmitter (2).
