In our day to day life we are depend on many things. If we can’t reach on time at any place ,the schedule will be destroyed. So I think Traffic signal is one of the important thing which save our day from getting destroyed only if we follow the rule.
Today is the day when the first electronic traffic signal was invented and installed on the corner of Euclid Avenue and East 105th street in Cleveland, Ohio, way back in 1914.
The first electric traffic light was developed in 1912 by Lester Wire, a policeman in Salt Lake City, Utah, who also used red-green lights. On 5 August 1914, the American Traffic Signal Company installed a traffic signal system on the corner of East 105th Street and Euclid Avenue in Cleveland, Ohio.
As we all know Traffic lights alternate the right of way accorded to road users by displaying lights of a standard color (red, yellow, and green) following a universal color code.
In the typical sequence of color phases:
- the green light allows traffic to proceed in the direction denoted, if it is safe to do so
- the yellow (or amber) light warns that the signal will be changing from green to red (and from red to green in certain countries, such as in the UK). Actions required by drivers on an amber light vary, with some jurisdictions requiring drivers to stop if it is safe to do so, and others allowing drivers to go through the intersection if safe to do so.
- a flashing yellow indication is a warning signal
- the red signal prohibits any traffic from proceeding
- a flashing red indication is treated as a stop sign
Flashing mode of Traffic signal:
In some countries traffic signals will go into a flashing mode if the controller detects a problem, such as a program that tries to display green lights to conflicting traffic. The signal may display flashing yellow to the main road and flashing red to the side road, or flashing red in all directions. Flashing operation can also be used during times of day when traffic is light, such as late at night.
Indian Traffic Signals Rules and Signs:
Basic Rules of the Road-
