Ecological traffic lights

ENABLES REDUCTION OF AIR POLLUTION AND FUEL CONSUMPTION

BASIC DEMANDS

Due to street traffic regulation, vehicle to stop on intersections is inevitable. The time each vehicle spends
waiting for the green light to turn on vary from one intersection to another and depend from many factors:
traffic intensity, the importants of streets which are crossing, etc. If car motors are running during red light
stop, they produce great emission of harmful gases. Avernes about this problem, initiated a development of so
called `ECO TRAFFIC LIGHT`.

ECO TRAFFIC LIGHT display duration of the red light up to
the moment green light turns on. On intersections with different street
priorities (traffic intensity) the red light on side directions may last
more than 60 seconds.
During that period of time, drivers can and should turn motors off.
That way they are reducing air pollution and consumption of fuel.
At each 5 seconds before the green light is to start, drivers can turn
their motors on, an at the time green light starts they move their vehicle.

ECO TRAFFIC LIGHT is placed in two parts signal head. In upper segment is displayed duration of red light in
seconds, and in lower segment message to drivers to turn their engines off. The same device can be used to
inform pedestrians on the crosswalks about duration of red and green light.
