Explanation

This is for prevention against car accidents in advance by giving visual warnings to drivers and pedestrians with an Alarm Device (using a signal lamp) on the acute angle or longitudinal sloped roads of a residential area, business area, School zone, local housing area, backside road or non-signal intersection
An environmentally-friendly system using solar energy (commercial electrical power system also available)
An active and intelligent safety facility to detect vehicles with the built-in optical sensors of signal lamps that warns about the approach of vehicles to drivers and pedestrians

Conceptual Diagram

Operation Principle(Installation Overview)

  • This is done by installing a signal lamp including an LED and sensors to detect the vehicles (the optical sensor detects the vehicle’s headlights) at the center of the intersection, supplying the power is supplied using a solar cell (Commercial electrical power is also available)
  • It gives a warning sign to the approaching cars or pedestrians by blinking the LED, if the entry of cars is detected

Operate

Daytime
The Yellow LED blinks all the time - This gives a warning to cars entering the intersection and also warns pedestrians
Night time
It detects vehicles using the optical sensors in the signal lamp.
If there are no vehicles
The LED blinks Yellow
If there is an Approaching vehicle
The LED blinks Red
The optical sensors in the signal lamp detect headlights at night time, if avehicle approaches the intersection, it will visually give a warning to any vehicles in the other direction by turning on the blinking Red LED (on the left and right side of the approaching vehicle)

Installation Profile

Operational Picture

No vehicle blinking Yellow LED

For the Approach of a vehicle blinking Red LED

Application Field

  • Intersections without signals (unsignalized)(Residential areas, Commercial Zones, Local housing roads etc.)
  • 30km/hr limit Zones (School zones, retiree zones, etc.)
  • Bicycle lanes
  • Curved and dangerous roads
