There are many reasons for this rapid flow of traffic and megacities. The main reason that can be assigned is the increase in population due to the increase in the number of vehicles on the road. In addition, there are many other causes of congestion such as inadequate capacity of roads, red and green lights leading to unnecessary time intervals, travel delays, incomplete information about traffic, inefficient traffic management, and unregulated demand. Inadequate capacity and unrestricted demand are interrelated, but the signal delay is inflexible, so do not depend on the magnitude of the traffic density. As a result, the need to optimize a traffic control system and increase it further will be dynamic to accommodate the changing traffic density. This article tells you the different traffic control techniques.

1.Manual traffic control management

This is the simplest form of traffic management and mainly involves human beings in this way. In this way, the policeman stands at each cross-section of traffic and controls the roads and the flow of traffic using the signboard.

2.Automatic Traffic Management Technique

This system includes simple three-colour traffic red, green and yellow signals. Normally 120 seconds of green light is on each lane [4] but traffic is light in some parts of the city; The intersection green light timing is less than 120 seconds. Overall, it depends on the traffic density in that area of ​​the city. Before the green light, the yellow light flashes for 20 seconds; Indicates that your vehicle should be ready to start and move.

3.Intelligent Traffic Management Technique based on Image Processing

This technology includes cameras used to capture images of traffic density on the road. Because they are high poles, they can travel long distances. Vehicles on the road analyze a computer chip with a camera to capture and locate the image. The computer calculates the time It sends this data to traffic signals for red and green signals to control traffic density; Accordingly, the information will become red and green signal dynamic their time. 

4.Traffic Management system using Wireless Technologies

When an emergency vehicle approaches the intersection, it sends a signal to the RF receiver and sends this receiver to the main control system.

The control system calculates the approximate time for the green signal to move the emergency vehicle and keep the red light on the remaining lane. Then the vehicle will pass easily. This technology effectively controls traffic flow and provides solutions for emergency vehicles.
