The latest technology called as LI-FI which has been developing a lot in few years. Traffic congestion and tidal flow management are two major problems in modern urban areas which lead to road accident and loss of life. Using the concept of LI-FI two vehicles are communicated with the help of LEDs bulbs with the help of transmitter and receiver circuit. A very chip device called as ultrasonic sensor which is used to measure the distance and also to detect any obstacles is used here just to communicate the two vehicles when they comes in the contact in some range which is preferred for the ultrasonic sensor. Using this LI-FI the data are transmitted from one vehicle to another. The data that is transmitted through LIFI can be any data like audio, video or text. This system aims at communicating with the vehicle in its surrounding with the help of its location to indicate their proximity. In this way the drivers can communicate with each other and act according to the situation. Visible light communication(VLC) is act as medium of this lifi technology to send a data at high speed between two devices. VLC are conducted to overcome the radio spectrum congestion.
