ABSTRACT:
A continuous horizontal road-marking tape is described. The road-marking tape includes Light Emitting Diodes (LEDs) or high intensity microlamps, solar cells and retroreflecting elements. The LEDs may be double and focused for better visibility, their light is pulsing at a regular speed or at an emergency fast speed. The road-marking tape balances the solar energy captured by its solar cells with the emitted light employed to signal or warn motorists. Also described is the use of an emergency fast pulsing for signalling an emergency or the presence of ice, and the use of the tape for controlling situations where a single lane of roadway must alternatively pass traffic from two different directions. Activation of the light emitting sources is by sensing light from headlights of oncoming cars or by traffic lights.
