Abstract
An improved traffic light includes interval lights which are controlled by a control unit mounted to the light housing. The control unit allows the use of existing wiring and makes the light periods dynamic, that is, the traffic light periods can be responsive to changes in traffic flow as well as to the approach of emergency vehicles in real time.
Claims (5)
1. A traffic light with time information comprising:
a control box having a stop light wire, a go light wire, a warning light wire and a common wire extending therefrom;
base lights arranged to indicate stop, go and warning when active;
a plurality of interval lights;
a control unit operably linked to the stop light wire, the go light wire, the warning light wire and the common wire and to the base lights and the interval lights such that said control unit activates an interval light when the stop base light or go base light is activated and activates subsequent interval lights in sequence while the corresponding base light is active.
a control box having a stop light wire, a go light wire, a warning light wire and a common wire extending therefrom;
base lights arranged to indicate stop, go and warning when active;
a plurality of interval lights;
a control unit operably linked to the stop light wire, the go light wire, the warning light wire and the common wire and to the base lights and the interval lights such that said control unit activates an interval light when the stop base light or go base light is activated and activates subsequent interval lights in sequence while the corresponding base light is active.
2. The traffic light with time information according to claim 1 including a message panel connected to the control unit for displaying text messages.
3. The traffic light with time information according to claim 1 including a plurality of glare reflectors positioned in front of the base lights and the interval lights.
4. The traffic light with time information according to claim 3 including a translucent cover mounted in front of the glare reflectors.
5. The traffic light with time information according to claim 1 including a slanted plate on top of the lights, which prevents the accumulation of snow and ice on top of the light housing.
