PROJECT DESCRIPTION

The project is designed to develop a density based dynamic traffic signal system having remote override facilities. During normal time the signal timing changes automatically on sensing the traffic density at the junction but in the event of any emergency vehicle like ambulance, fire brigade etc requiring priority  are built in with RF remote control to override the set timing by providing instantaneous green signal in the desired direction while blocking the other lanes by red signal for some time.

Traffic congestion is a severe problem in many major cities across the world thus it is felt imperative to provide such facilities to important vehicles.

Conventional traffic light system is based on fixed time concept allotted to each side of the junction which cannot be varied as per varying traffic density. Junction timings allotted are fixed. Sometimes higher traffic density at one side of the junction demands longer green time as compared to standard allotted time.

The proposed system using a microcontroller of 8051 family duly interfaced with sensors, changes the junction timing automatically to accommodate movement of vehicles smoothly avoiding unnecessary waiting time at the junction.

The sensors used in this project are IR and photodiodes are in line of sight configuration across the loads to detect the density at the traffic signal. The density of the vehicles is measured in three zones i.e., low, medium, high based on which timings are allotted accordingly. The override feature is activated by an on board RF transmitter operated from the emergency vehicle.

Further the project can be enhanced by synchronizing all the traffic junctions in the city by establishing a network among them. The network can be wired or wireless. This synchronization will greatly help in reducing traffic congestion.

I got to know about Edgefx while I was searching for Traffic projects in Google.
Since Edgefx is providing Do it yourself kit also so decided to buy my project from Edgefx. I liked the explanation of video.
Purchased through online.

For me things are fine and not facing any problems so no changes keep doing the same work.

I had known about EDGEFX through one of my friend.
I have seen the video on YouTube, and I have entered into your website for purchasing the product through online.

I directly placed order through online with the help of my friend.
I am satisfied with my project
