Smart accident detection systems are systems that automatically detect accidents. IoT (Internet of Things) can connect different hardware, especially sensors, and can do processes using the information received from sensors, which lead to accident detection; and then this information is made available to relevant authorities such as medical emergencies and the police. In this research, some of the most recent methods for car accident detection using IoT technology are investigated and then obstacles, challenges and future trends are analyzed and compared.
