Abstract

A traffic light has three individual elements for producing a green signal, a yellow signal, and a red signal, and control unit for controlling the producing unit, the control units being formed and operating so that the element producing the green signal first generates a permanent non-blinking green light and thereafter the same element producing the permanent green light generates a green light which flashes for three-six seconds immediately before the yellow signal is produced, to give drivers an additional period of time to decide whether or not to stop when the yellow signal appears.

Claims

1. A traffic light, comprising three individual elements for producing a green signal, a yellow signal, and a red signal;

and control means for controlling said producing means, said control means being formed and operating so that the element producing the green signal first generates a permanent non-blinking green light and thereafter the same element producing the permanent green light generates a green light which flashes for three-six seconds immediately before the yellow signal is produced, to give drivers an additional period of time to decide whether or not to stop when the yellow signal appears.

2. A method of controlling a traffic light, comprising the steps of producing a green signal, a yellow signal, and a red signal by three individual elements;

and controlling the producing of the signals so that the element producing the green signal first generates a permanent non-blinking green light and thereafter the same element which generates the permanent green light generates a green light which flashes for three-six seconds immediately before the yellow signal is produced, for giving drivers an additional period of time to decide whether or not to stop when the yellow signal appears.
