Aim of the ProjectThe proposed project aims to monitor traffic lights distributed in different routes using an android app. Through this app user can check how much time is remaining for switching from GREEN to RED light. To provide user with shortest route so that he can reach his destination on time by avoiding long traffic signals.OBJECTIVES

To help in selection of best path or route by the user to reach destination without waiting for red light. To monitor all traffic lights of street over application and websites. To Know in advance about traffic light timing to help avoid traffic jams. For rerouting.

Seven segment displays is used to show count-down display. Street light count-down display is controlled by the microcontroller AtMega 32 and synched timing of the street light is exposed as a web service to IOT module. Each IOT module is assigned with an IP address. The developed android app communicates with the Hardware system through IP address assigned to the IOT module with the help of a router.

Hardware Module Microcontroller programmingSeven Segment displayWifi module connectivity Testing HARDWARE MODULE DISTRIBUTIONANDROID APPLICATIONSTEPS PERFORMED :We programmed microcontroller in AVR version 4.0 ,avr itself compiles it, Avr ISP burner to transfer data to microcontrollerSeven segment display is used to display timings.LEDs are used to show status of traffic lights.These all are programmed in order to function as traffic signals with timing display just like the real ones.Wifi module has been connected to the serial ports and the testing process is now finally complete.

PROTOTYPE WORKINGAFTER A SPAN OF 60 SECONDS THE COLOUR OF THE LED CHANGES FROM RED TO GREEN OR VICE VERSA

TESTING PROCESS OF PROTOYPE The testing of the prototype is done after the connection of wifi module to the microcontroller.The wifi module is allotted an ip address.The router of the wifi module is connected to the pc.Then the ip address of the module is entered in the browser to check wheather the microcontroller details are right or not.There was signal loss during the process so we decided to change the router chip we are using and the problem was solved. Since are details displayed in the site were correct so we decided to proceed with the android application.

FUTURE WORKAndroid application for showing the information of the prototype i.e. our traffic lights will be developed .
