The project is designed to develop a density based dynamic traffic signal system. The signal timing changes automatically on sensing the traffic density at the junction. Traffic congestion is a severe problem in many major cities across the world and it has become a nightmare for the commuters in these cities.

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.

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 was searching for engineering project on google then i got Edgefx. I have contacted Edgefx through Call I have decided to buy kit from Edgefx because the kit was very good and I like the complete kit. The kit was delivered on time wit all the components. Sirisha Madam has helped me in purchasing the project. She gave me additional discount coupon code. Everything is good and at Edgefx and I like the documentation part. I will reference to other students

    I was been Suggested the project through our HOD from Edgefx. Because i especially looking for mainly soft copy,that’s why i purchased project kit. purchased through online. Good experience with your technical team,when i have a conversation with them about my query and my query has been solved at that time itself.So,that i can able to submit my project on time.

    While I was searching for the projects, my friend informed me about the URL i.e., I decided to buy a kit from Edgefx because the Hardware is assembled properly. I like the complete DIY kit.Yes it’s delivered to me on time.No I directly purchased through online.Improvement should be in Technical Aspects.
