ABSTRACT:
A hazard warning and traffic control system includes a housing having at least two display faces oriented at an angle relative to one another, and an electronic controller including a timer. Each of the display faces contains multiple fields, and each of the fields includes many illuminating members. Each of the fields can be selectively lit, and can display indicia. The controller selectively illuminates the illuminating members to change the display at timed intervals. Each of the display faces includes a STOP field, a DANGER field, and a go field. The larger STOP field is at the bottom of the display face and has a red background. The DANGER field is located above the STOP field and has a yellow background. The go field is located above the DANGER field and has a green background. Each display face may further include a street name, as well as other optional features that significantly promote intersection safety.
