Tram-car indicator - the device is mounted on a tram and a car. Tram indicator sends a signal to the car of the tram stop when the driver of the car does not see this because of another car standing. Then, the device stops the car by force. This allows passengers to exit safely from the tram rail. Modern technologies allow us to realize it. More questions arise during the implementation phase of development, when the life of the passengers appreciate cheaper fines. The base unit can be selected "TomTom GO" or other navigators.
