Yes Actually they do.. A scientist named Mike McAdams did a test on how long it took for the light to change without pressing the button, which took 2 minutes to change, but then he pressed the button and it only took 1 minute, 28 seconds.!!! And there is a code that allows you to change the light Immediatley by the button itself. Here is the Code: 3 Fast Clicks, 2 clicks, holding on the each of the two for atleast 5 seconds, 1 fast, 2 held ones again, and then 3 fast clicks, So it should be: click click click, cliiiiccckkkk, cliiiiicccckkk(holding down for 5 seconds), click, cliiiicccckkk cliiiiicccckkkk, then click click click!!

As of 2011, there were more than 25,000 sets of traffic lights in the UK. There was a 30 percent increase in traffic lights from 2000 to 2008.
They do, if they are placed on London's major routes.
Because the vehicle stays at a steady speed and has less starts and stops (at traffic lights).
That depends on where you drive, how much you drive, how often you drive,and what route you take. There is a traffic light about 3 blocks from my housethat has not changed since about 1992. Three cars are still lined up waiting.I avoid it.
If you were going 70 mph for 190 miles on a straight road, with no stopping, traffic lights etc (which is almost impossible to avoid, especially for 190 miles), it would take approximately 2.7 hrs. Remember: this is on a straight road, no stopping, no traffic lights, no traffic and nothing to stop you. This is also counting on not stopping for extra fuel.
A computer that the trafic lights are conected through.
The advantages of traffic lights are; they control the flow of traffic making it easier for drivers and safer for pedestrians, they reduce the risk of accidents and they lower the chances of traffic jams, etc.....
In the US - it greatly depends on the state and how the pedestrian laws are written for that state. GENERALLY - a pedestrian crossing at a MARKED crosswalk, and in conformance with any pedestrian signals or traffic lights, will legally have the right-of-way, but you DO have the responsibility to make sure you can do it in a safe manner.
Crosswalks A crosswalk is that part of the pavement where the sidewalk lines would extend across the street and it is set aside for pedestrian traffic. Every intersection has a pedestrian crosswalk whether or not there are painted lines on the street. Most crosswalks are at corners but they can also be in the middle of the block. Before turning a corner, watch for people about to cross the street. Pedestrians have the right of way in crosswalks. Crosswalks are often marked with white lines. Yellow crosswalk lines may be painted at school crossings. Most often, crosswalks in residential areas are not marked. Some crosswalks have flashing lights to warn you that pedestrians may be crossing. Look for pedestrians and be prepared to stop, whether or not the lights are flashing.

Location: School control typically refers to a school crossing where a crossing patrol officer assists pedestrians, while a pelican crossing is a type of pedestrian crossing with traffic lights to regulate the flow of vehicles and pedestrians. Control mechanism: School control relies on the presence of a crossing patrol officer who manually stops traffic to allow pedestrians to cross, whereas a pelican crossing uses traffic lights to control the flow of vehicles and pedestrians. Visibility: School controls are often marked by signs and flashing lights to indicate the presence of a school crossing patrol officer, while pelican crossings are visually marked with yellow stripes on the road and pedestrian signal posts.
green colours are signal to run . Eg., traffic lights
Safer roads and also helped the life of pedestrians who had to cross roads. Although you could argue they slowed down driving quite a bit.
City driving tends to be stop and go, with many traffic lights, other vehicles and pedestrians. Driving on the highway is, usually, more straight forward, with less stops unless there is an accident, or a traffic jam.

If there is a crosswalk, use it. Wait for the walking person icon before walking.Stop, look, and listen. Stop before crossing. Look both ways a few times to make sure you see no cars approaching. Listen for car engines. If all is clear, cross.If you have a bike, skateboard, or scooter, do not use them while crossing.Think safety first and cross the road!
By first checking both sides of the road - utilizing any road-crossing traffic buttons, lights, or designated crossing zones.
In 1868, the first traffic light was built in front of the British House of Parliament. Even though there were not yet cars on the road, the horses and pedestrians caused chaos on the streets of London. The light was proposed by John Peake Knight, a railroad engineer.
