Connected vehicle safety applications are designed to increase situational awareness in the event of accidents through vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. This project has the idea of ​​preventing accidents. In this project all this communication takes place with IOT (Internet of Things). IOT technology can be used to provide communication and interaction between vehicles and infrastructure along the roadside. By connecting vehicles and road infrastructure to the Internet it is possible to achieve real-time communication, monitoring, control and notifications (early warning system). Due to road accidents many people lose their lives every year around the world and many more people have been injured and maimed. The main reason for these accidents is a limitation to road emergency events which may be due to distances, darkness, the presence of an inhibitor on the road. Road and traffic safety can be improved if drivers have the ability to hear further away from the road and know if a collision has occurred. This can become possible if drivers and vehicles communicate with each other. If information about infrastructure were provided to motorists, roads would be safer and traveling on them would become more efficient. We propose V2V and V2I communication link to prevent road accidents. There are some problems with the current system, so we are developing this iterative system for traffic accident prevention. Here communication is established between vehicle and vehicle and between vehicle and infrastructure so that the driver can drive more easily. Radio frequency is used for vehicle-to-vehicle and vehicle-to-infrastructure communication. We are using IOT sensors like Ultrasonic, Proximity and DHT11 for data sensing and some data is sent to the cloud. This project has the idea of ​​preventing accidents. In this project all this communication takes place with IOT (Internet of Things). IOT technology can be used to provide communication and interaction between vehicles and infrastructure along the roadside. By connecting vehicles and road infrastructure to the Internet it is possible to achieve real-time communications, monitoring, control and notifications (early warning system). The purpose of this system is to evaluate the readiness for the application of vehicle-to-vehicle (V2V) communications. , a system designed totransmit basic safety information between vehicles to facilitate alerts to drivers of impending crashes. Working In our project we create a communication link between vehicle to vehicle and between vehicle and infrastructure. Since this model of receiver is placed in the vehicle, with the help of this we give an audio notification to the driver. For communication between vehicle and vehicle and between vehicle and infrastructure we used RF433 MHZ. Each vehicle is equipped with a short-range RF receiver through which it will interact with the nearby RF transmitter. In our project we use the following sensor: Ultrasonic Sensor: Ultrasonic sensors measure distance using ultrasonic waves. The sensor head emits an ultrasonic wave and receives the wave reflected from the target. Ultrasonic sensors measure the distance to the target by measuring the time between emission and reception. In our project we use an ultrasonic sensor to measure the distance between the front vehicle and a rare vehicle during night and foggy areas. Proximity sensor: A proximity sensor is a sensor that can detect the presence of nearby objects without any physical contact. To detect objects, the proximity sensor radiates or emits a beam of electromagnetic radiation, usually in the form of infrared light, and detects reflection to determine the proximity or distance of the object from the sensor. We use a proximity sensor to detect nearby vehicle and sharp turns.DHT11: The DHT11 is a basic temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and sends a digital signal to the data pin. We use this sensor to measure fog in the winter season. Advantages Reduces accidents. Extended driving visions. Reduces loss of life and property. To reduce travel time. Thanks to this technology, people's driving will be safer, more comfortable and easier. Algorithm Step 1: The user begins the journey, the vehicle approaches the sharp turn, and the user receives an audio notification that the sharp turn is ahead. Step 2: The vehicle approaches the bridge, then 200 meters before the user receives the notification, the bridge is ahead. Proceed slowly. Step 3: Then traffic sign come, 200 meters before the user gets a notification about it. Step 4: Then the vehicle enters the fog area, then the user gets a notification about the nearby vehicle. Step 5: Then no horn zone detects on the road user receives a notification about it. Step 6: At night the user gets notified about obstacles on the road. Literary Survey Swati B. Raut developed a VANET to reduce vehicle collision and congestion control at road intersections, efficient vehicle monitoring requires time for smooth traffic flow. It uses intelligent control unit (ICU) and vehicle-to-vehicle communication to predict the probability of collision at highway intersection. The scheme is implemented on an open road map, on the position of interest and makes use of an alarm system based on the probability of collision. The simulation results show the collision probability for near miss, no miss and accident. In VANET, the problems are Analysis of existing VANET protocols has shown that most of them cause a performance bottleneck under heavy traffic conditions. The main problem with these protocols is the large packet size, which leads to increased encryption and communication costs. The above situation motivated this research to look for a reliable solution to support both V2I and communicationsV2V, while reducing the aforementioned overheads that are not adequately addressed by other studies. The main concern of this research is to propose an efficient protocol that can meet the scalability requirements and reduce message loss. GOH CHIA CHIEH proposes a new vehicle-to-vehicle (V2V) communication system for collision avoidance that combines four different wireless devices (GPS, Wi-Fi, Zigbee and 3G) with an embedded low-power Single Board Computer (SBC) to increase processing speed while maintaining a low cost. Data processing for collision avoidance includes data processing for vehicles on expressways, roads, tunnels, traffic jams and internal V2V communications as required in car parks. Wi-Fi based system: In Wi-Fi based system there are limitations for the user in heavy traffic conditions. The Wi-Fi hotspot only communicates with 10 users at a time. Initially in Wi-Fi based system time where user has to manually connect to hotspot for communication. Under heavy traffic conditions there is the possibility of notification delays and network collapse. Country Survey: Every minute there is a serious road accident in the country and every hour 16 die on Indian roads. 1,214 road accidents occur every day in India. Two-wheeled vehicles account for 25% of total road accident deaths. Every day in the country 20 children under 14 die due to road accidents. 377 people die every day, the equivalent of one jumbo jet crashing every day. Maharashtra Survey: Every day, on an average, up to 115 road accidents occur in Maharashtra and 37 people die in these accidents, reveals the annual crime report released by the Crime Investigation Department. In Pune, there are an average of four accidents per day and three deaths every 48 hours, the report said. The maximum number of road accidents stood at 3,123 in 2017 in Aurangabad, followed by Mumbai (2,551) and Navi Mumbai (2,223). Mumbai topped the list of road accident deaths with 611, followed by Pune, which saw 543 such deaths. In 2017, Maharashtra witnessed 42,250 accidents, in which 13,685 people died and 39,301 were injured. In 2016, there were 44,382 traffic accidents in the state, in which 13,529 people died and 43,668 were injured. While the number of accidents decreased by 4.8%, the number of deaths increased by 1.15%. According to the World Health Organization (WHO), road accidents cause around 1.2 million deaths worldwide every year. Furthermore, approximately 50 million people are injured in road accidents. In Western Europe, a decrease of just 5 km/h in average vehicle speed could lead to a 25% decrease in deaths. The National Highway Traffic Safety Administration helps reduce deaths, injuries and economic losses resulting from motor vehicle crashes by establishing and enforcing safety performance standards for motor vehicles and motor vehicle equipment. Vehicle manufacturers meet NHTSA standards by building safer vehicles. Combined with state and local government efforts, market effects, and improvements in driver behavior, NHTSA standards have contributed to a significant reduction in annual roadway deaths and injuries, from 52,627 deaths in 1970 to 32,479 deaths in 2011. Safety technology has developed rapidly since the NHTSA began regulating the automotive industry: vehicles protect occupants much better in crashes thanks to advanced structural techniques propagated by more rigorous crashworthiness standards, and some Accident-avoidance technologies are now standard..
