A review on action recognition for accident detection in smart city transportation systems

Abstract Accident detection and public traffic safety is a crucial aspect of safe and better community. Monitoring traffic flow in smart cities using different surveillance cameras plays a crucial role in recognizing accidents and alerting first responders. In computer vision tasks, utilizing action recognition (AR) has contributed to high-precision video surveillance, medical imaging, and digital signal processing applications. This paper presents an intensive review focusing on action recognition in accident detection and autonomous transportation systems for smart city. This paper focused on AR systems that use diverse sources of traffic video, such as static surveillance cameras on traffic intersections, highway monitoring cameras, drone cameras, and dash-cams. Through this review, we identified the primary techniques, taxonomies, and algorithms used in AR for autonomous transportation and accident detection. We also examined datasets utilized in the AR tasks, identifying the primary sources of datasets and features of the datasets. This paper provides a potential research direction to develop and integrate accident detection systems for autonomous cars and public traffic safety systems by alerting emergency personnel and law enforcement in the event of road traffic accidents to minimize the human error in accident reporting and provide a spontaneous response to victims.
