U. vijay.rathod25bel@gmail.com Vishwabharati Academy's College of Engineering, Ahmednagar, Maharashtra ABSTRACT In this paper, we have discussed the problem of traffic and how to solve it using WSN and IoT. As we know IOT is the latest technology and is being used in many sectors nowadays at it very effective. As we know the problem of traffic management is increasing nowadays is big cities which causes many problems like traffic, accidents, and pollution. Management of traffic is very important and a tedious job. There have been many methods used to solve these Problems. Also, the issues like car theft have also increased nowadays, also due to high traffic ambulance also have problems in reaching the hospitals fast. In this paper, we have discussed the technique of solving this problem using IOT. There will be a sensor node and a base node the sensor node will be used to count the traffic in each lane and will send the information to the base node and the base node will take the decision of allocation of them. Also, the base node will have an RFID reader connected which will be continuously Reading for the RFID cards that will be present at the cars and compare it with the database and search for the stolen cars and ambulance and will notify after the stolen car is detected. This will help to solve the traffic management problem the theft problem and the emergency situations for the ambulance. Keywords— IoT, WSN, RFID 1. INTRODUCTION The traffic signaling system is a vast field where WSN and IoT can help solve the problem using Sensors to detect the traffic load. Wireless sensors network can be used in the detection of the traffic load. These sensors require very few power as they run on the sensor. These sensors are connected to a battery which is charged using sun at day times so that it can be used for the latter half day. Consider an area with high traffic where there is vehicles like car, motorcycle, trucks, ambulance and VIP cars. Traffic signal present now has hardcoded timings which cannot be changed. This can lead to wastage of time that can be precious in terms of an emergency vehicle. In order to handle such situations the proposed system has two parts the base node and the sensor node. The proposed system uses the Wireless sensor method for the same. The Base node will be having the sensors that will detect the traffic density. After measuring the traffic density at the 4 lanes it will send the data to base node about the same. The sensor nodes will be connected to the base node wirelessly using Wi-Fi. After getting the traffic density the base node will take the decision about the timing and allow the priorities and timing accordingly. The base node will also have RFID readers connected to which will detect the RFID cards that are present on the car. After reading the RFID cards it will compare that to the database and search for lost vehicles an emergency vehicles and perform the appropriate operation 2. LITERATURE SURVEY There have been many systems implemented for traffic management systems. All the systems have their own drawbacks Traffic conjunction is a serious issue nowadays because of it there are many problems caused like getting late and a design was developed with the use of PIC microcontroller, Infra-red Sensors, and ZigBee. IR sensor was used to decide the traffic density and the ZigBee was used for emergency situations, moreover, the system only operated in automatic mode and it didn’t have any manual control over it [1]. To pass a number of vehicles an Algorithm was also designed. There was a priority number that was given to the different type of vehicle. A vehicle like Ambulance, Fire Brigade are given First Priority. Next Priority will be given to VIP vehicles. The priority will be given also on the basis of traffic density. The road that has traffic density high will have high priorities [2].
