One law enforcement agency in Japan reportedly wants to make something normally confined to sci-fi crime thrillers a reality: interactive, AI-powered reconstructions of real-world accidents. According to The Japan Times, Tokyo’s Metropolitan Department is developing a system that combines AI with security camera footage and 3D spatial data captured by camera-equipped mapping vehicles to digitally reconstruct traffic accidents. Investigators using the tool would reportedly be able to measure vehicle speeds and distances on a screen and replay the event in simulation from multiple perspectives, including overhead or even through the eyes of a nearby driver or pedestrian.
That’s the goal, at least. Details about how this proposed system will actually work remain sparse, though the report says that the police plan to begin testing in June 2027 and potentially launch full operations in January 2028. In theory, digital reconstructions could reduce the need for labor-intensive physical, on-site inspections (the current approach) which can close off roads for ours and lead to traffic jams.
