12’’ Traffic Signs Light for Motorways in Pakistan

This is a traffic signs light project for urban road motor vehicle lanes in Pakistan. It was completed in 2018. The diameter of 300mm red, yellow, and green direction arrow traffic lights were selected. The road has 4 lanes in both directions, one of which has two lanes.

Traffic Signs Light manufacturers in pankistan.Each lane is installed with a set of red, yellow, and green arrows. Signal lights give signal instructions to vehicles driving in each lane, and 300mm red and green pedestrian signal lights are installed on the sidewalk.

Customer Feedback
We needed to change our lights from incandescent to LED due to power consumption. I spoke with the folks at ZGSM and they very simply explained everything we need plus other options. Lights mounted in minutes and wired very easy. Thank you for all your help.

Traffic signal coordination is when two or more LED traffic lights are working together so that cars moving through the group of signals will make the least number of stops possible.

In order to have coordinated traffic lights, each signal in the group must be able to provide the green light to all movements at a predetermined time period. Typically, the selected time period is decided by the biggest intersection of the most distinct motions. This is often a junction with protected left-turn arrows and broad cross streets. Therefore, the duration of time that is set for each traffic light (the cycle length) may be rather lengthy.

Therefore, if you are waiting for a green light to cross the “coordinated” street where there are protected left-turn arrows and there is very light traffic on the side street, you will likely feel as though you are waiting for a long time, despite the fact that you should rarely have to wait for more than two minutes.

The pedestrian signal allows pedestrians sufficient time to enter the roadway on the steady walk signal or walking person symbol and to complete crossing the street on the flashing don’t walk signal or raised hand signal. The signal is typically actuated by a push button, which allows the traffic signal controller to execute a pre-programmed sequence of walk and flashing don’t walk indicators.


Pedestrian signals consist of the walk and don’t walk signals or the international symbols depicting a person walking for the walk signal and a hand for the don’t walk signal. The pedestrian indication is presented in white, whereas the pedestrian prohibition indicator is displayed in Portland orange.


The pedestrian signal sequence normally lasts between four and seven seconds, beginning when the walk signal is activated. This sequence should be long enough for a pedestrian to leave the curb and begin crossing the roadway before the start of the clearing period.


The pedestrian clearance period is comprised of the flashing do not walk signal. During this timeframe, the pedestrian is expected to have completed crossing the roadway. On the other hand, the pedestrian should not begin crossing the street while the flashing “don’t walk” signal is in effect.

The pedestrian clearance interval is typically calculated by dividing the street width by the assumed walking speed of four feet per second unless a special study indicates that a longer time interval is required for all pedestrians to cross the street safely; for elderly pedestrians, a slower walking speed of 3.5 feet per second is commonly used. Typically, the actual distance used to compute the clearing interval is the distance from the curb on the near side of the street to the center of the last traffic lane on the far side of the street.


WARNING: Pedestrians have the right of way at both marked and unmarked crosswalks; nevertheless, pedestrians and vehicles should be very cautious when pedestrians are present at a pedestrian signal since right turns on red are permitted unless banned.

There are two main types of traffic light signal operations: fixed-cycle and vehicle-triggered.
