Traffic warning system for detecting and warning of bicycle traffic

1. A traffic warning system for detecting and warning of bicycle traffic, comprising:

mounting at least one warning device on a roadway, the warning device comprising: a motion sensor configured to detect motion indicative of bicycle traffic, and a visual signal indicator configured to generate a visual warning signal upon detection of said motion indicative of bicycle traffic by said motion sensor,

the warning device being mounted in a location and in an orientation configured to detect bicycle traffic, and to generate said visual warning signal in a direction towards oncoming motor vehicle traffic upon detection of said motion indicative bicycle traffic,

wherein the generated visual warning signal has a preset time duration,

wherein the warning device comprises housing which supports said visual signal indicator and said motion sensor, the housing further protectively enclosing an energy storage element, and circuitry,

wherein the warning device is a self-contained and stand-alone unit that operates autonomously, and is not interdependent on the operation of other remotely located devices for generating said visual warning signal.

2. The traffic warning system of claim 1 , wherein the warning device is mounted on or proximate a lane divider line that separates between a vehicle lane and a bicycle lane, the warning device being oriented to detect cyclists within the bicycle lane.

3. The traffic warning system of claim 1 , wherein motion indicative of bicycle traffic comprises slow moving traffic.

4. The traffic warning system of claim 1 , the visual warning signal comprising a flashing light and/or a continuous illumination.

5. The traffic warning system of claim 1 , wherein a signal indicator port of the visual signal indicator and a motion sensor port of the motion sensor are integrated into the surface walls of housing.

6. The traffic warning system of claim 5 , the warning device further comprising a solar panel integrated into the surface walls of the housing and configured to supply power to the energy storage element.

7. The traffic warning system of claim 5 , wherein the housing has a rectangular cross section.

8. The traffic warning system of claim 7 , wherein the housing has front, back, left-side, and right side surface walls which are angled inwards and trapezoidal shaped.

9. The traffic warning system of claim 7 , wherein the signal indicator port and the motion sensor port are provided on adjacent surface walls of the housing, the signal indicator port being on a front surface wall, and the motion sensor port being on a side surface wall, wherein the front surface wall is shorter than the side surface wall.

10. The traffic warning system of claim 9 , further comprising a solar panel on a top surface wall of the housing.
