Abstract: The large number of job opportunities in the city, constantly increases the population, in turn, the number of vehicles in a city also increases and it is difficult to manage traffic manually. In order to manage the traffic efficiently an automated system is required. The automated system is, designed to monitor the vehicular movement in each lane. The information is, sensed and sent to the nearby coordinators system to compare the information received. The lane, which has more vehicles, will get more time with go signal indication. Keywords: Bluetooth, Arduino Board, Motion sensor I. INTRODUCTION Bluetooth Low Energy (BLE) is, developed as a part of Bluetooth version 4.0. It is smaller and highly optimized version of basic Bluetooth technology. It is a backbone of Bluetooth technology, but practically, BLE has come from different family and it has different aim. BLE initially designed and developed by Nokia by the name Wibree, and later accepted by the Bluetooth Special Interest Group (SIG). By the establishment, the main objective is to propose a radio standard having minimum possible utilization of energy, explicitly designed for lower price, less bandwidth, minimum energy, and less intricacy. In June 2010, Bluetooth SIG group introduces Bluetooth Low Energy with the version 4.0 specification. The specification had lot of controversies over the years. The first major update is Bluetooth version 4.1. On December 2013 it was released and that is the present available reference for those who are designing and developing products based on BLE technology. II. PROPOSED METHOD In the figure-1, shows there are five lanes and in each lane the traffic density keep changing throughout the day, this need to be handled dynamically. To handle dynamically the man power required is more thus it is automated in the proposed methodology. The maintaining traffic automatically, considers three main devices such as BLE device, Motion Sensors, and Arduino boards are placed at the each lanes of the road. Motion sensor are use to detect the vehicles from each lane and then transmit the vehicles information to the Arduino board, because sensors are build on the Arduino platform. The information received by the sensor is transmitted to the co-ordinator by using BLE device. On receiving the information about vehicles from all lanes through respective BLE devices, the co-ordinator node will process the data based on the received data and it generates the results to the respective lanes after completion of the process.
