Alarm System at Street Junctions (ASSJ) to Avoid Accidents Using VANET System

There are numerous applications for VANET that will be used in the future to improve road safety and develop intelligent transportation systems. It will give authorities complete visibility to monitor the street, street junctions, vehicles, and rush of vehicles and accidents that occur during the day/night hours, affecting traffic status in general. This paper develops a new methodology for running an alarm system in a vehicle, Alarm System at Street Junctions (ASSJ). According to the method, an alarm will sound to warn the drivers if the threshold is reached. After calculating the vehicle's speed or the distance between vehicles based on their locations, if the system predicts that a crash accident is likely to occur after a certain time – determined after tuning –, an alarm message sound/light will be generated in the vehicle to alert the driver. If this ASSJ methodology is implemented, it will improve the overall safety of transportation systems. One of the key characteristics of this methodology is that it is not primarily reliant on the backbone network but rather on exchanged communications between vehicles (V2V) and between vehicles and the infrastructure RSU, with each vehicle having its onboard unit OBU with processors, memory, and sensors
