An array is a data structure consisting of a collection of elements or a container, which can take a fixed number of elements, and these elements should be of the same type. The simplest type of data structure is a linear array. Traffic lights are the signaling devices used to manage traffic on multi-way road. These are positioned to control the competing flow of the traffic at the road intersections to avoid collisions. By displaying lights (red, yellow and green), they alternate the way of multi-road users. The implementation of traffic Light Controller can be through a Microcontroller or Field Programmable Gate Array.

The steady development of individuals from provincial to urban territories looking for greener fields has brought about urban populace blast and over-extended foundations. One of such over-extended framework is the street, a circumstance which has finished to expanded traffic. Despite the fact that traffic lights have dependably been utilized for controlling the development of traffic (person on foot or car), traffic the board in significant urban areas around the globe has kept on being a subject of concern. While trying to handle the traffic the board concern, different structures have either been proposed or actualized. From that point forward, advanced development has discovered application in its utilization for overseeing traffic in urban areas without traffic superintendents or officers; however, with developments, changes have been made in signs, yet the working standard for traffic and person on foot control continues as before.


With the fast development in the number of inhabitants in our urban areas, the bustling idea of our streets and the need to augment one's time, there emerge a requirement for a progressively unique, deliberate and effective traffic the executives plot one which looks to diminish superfluous blockage and disorder coming about because of undue deferrals. It would be basic that another structure be grown to upgrade the stream and control of traffic utilizing the thickness of vehicles on a specific path via naturally allocating the left-after some time in an inactive path to the path with more traffic thickness, thus, diminishing traffic clog in those paths and in the meantime catch the vehicle permit number plate of street clients who defy traffic utilizing the observation framework. The point of this work is in this manner to structure a thickness based traffic light control framework with a reconnaissance-checking framework utilizing the innovations. Studies have been done all with the point of improving the traffic the executive’s framework; depicted the demonstrating and usage of a propelled traffic flag controller inside an infinitesimal reproduction condition. The controller was planned with a conventional and adaptable rationale that enabled it to recreate control techniques.

At first the North traffic will be permitted to move and afterward traffic in the East, South and West bearing will be permitted to move in arrangement. The upside of composing Traffic Light Controller program is that in a program, changes according to prerequisites should be possible effectively i.e., assume the traffic on principle street ought to be took into account additional time and for side streets the traffic ought to be took into account less time; at that point the check is isolated so that for primary street the clock time frame will be more and for side streets the clock time frame will be less, this is on the grounds that the primary street traffic is substantial when contrasted with the side street traffic. All in all TLC System will have three lights (red, green and yellow) toward every path where red light represents traffic to be halted, green light represents traffic to be permitted and yellow light represents traffic will be ceased in a couple of moments seconds. Nevertheless, in this paper, yellow light is part into two stages and are incorporated into the flagging lights alongside red and green lights so as to demonstrate that in the principal period of yellow light, person on foot while OFF and in the second stage, passerby will be ON. Traffic blockage has been causing numerous basic issues and difficulties in many urban areas of present day nations. To a worker or explorer, clog implies lost time, botched chances, and disappointment. To a business, blockage implies lost specialist profitability; exchange openings, conveyance delays, and expanded expenses. To take care of clog issues is attainable not just by physically developing new offices and arrangements yet additionally by structure data innovation transportation the board frameworks.


The proposed system implemented advanced traffic light control system, which control complex traffic in modern cities. This system uses FPGA, which made this system advanced FPGA is device, which is configured by designer or user. The very useful application of FPGA is that designer can change the program at any instant, which is easy to reprogram. User can change the program as per requirement. Verilog HDL is used to circuit description. Now a day’s problems related to traffic are very serious issue due this problems number of accidents increases rapidly in modern cities. Because of lack of management in TLC system road user loss their valuable time. So to overcome these disadvantages we need some what advanced TLC system. FPGA is very good replacement for that traditional TLC systems with microcontroller having fixed time slots. This four rode TLC structure with FPGA can solve any complexity related to traffic. FPGA is many times advantageous than microcontroller, ASIC designs and also having low cost.
