Toyota Mobility Foundation (Chairman: Akio Toyoda, hereinafter “TMF”) held the fourth Tateshina Meeting in Chino City, Nagano Prefecture, to advance discussions and initiatives toward realizing zero traffic accidents. Since its launch, the Tateshina Meeting has centered its discussions on the belief that achieving zero traffic accidents requires a three-pronged approach focusing on cars, people, and traffic infrastructure. In recent years, the Tateshina Meeting subcommittees have expanded these efforts through multifaceted initiatives and demonstration projects aimed at developing more effective traffic safety measures. They then discussed the challenges ahead and future directions for realizing zero traffic accidents from two perspectives: behavioral change and infrastructure coordination. Building on this shared understanding, participants exchanged views on the following approaches toward realizing zero traffic accidents.
