New Tests Using Virtual Dummies Aimed At Saving Real Pedestrians

Toyota and the University of Virginia are developing virtual crash test dummies that could dramatically reduce pedestrian fatalities by simulating accidents no physical dummy can replicate. The Japanese automaker and the U.S. university have launched a joint research project to create highly realistic virtual pedestrian models that promise to make vehicle safety testing faster, cheaper, and more representative of real-world conditions. Pedestrian deaths have been rising in the United States, with more than 7,500 fatalities recorded in 2024 alone, according to the Governors Highway Safety Association. Traditional crash test dummies are expensive, limited in number, and cannot simulate the wide variety of human body types, ages, and movements. Virtual models can be programmed to mimic millions of different pedestrian profiles, from children to elderly adults, and can account for variables like walking speed, posture, and clothing. The project combines Toyota's decades of expertise in vehicle safety with the University of Virginia's Center for Applied Biomechanics, a leading institution in injury biomechanics research. The virtual dummies will be used in computer simulations of crash scenarios, ranging from low-speed city streets to high-speed highways. Each model will include detailed biomechanics of bones, organs, and tissues to predict injury patterns more accurately than physical dummies. Researchers say this granularity is critical for designing cars that better protect pedestrians, especially as SUV and truck sales grow and those vehicles pose greater risks. This research could accelerate the adoption of pedestrian detection and automatic braking systems by providing better data for algorithm training. It also reduces the ethical and practical limitations of using cadavers or human volunteers in crash tests. Moreover, virtual testing is far cheaper—Toyota estimates it can run thousands of pedestrian crash simulations in the time it takes to set up a single physical test. 'What we learn from virtual dummies can be applied directly to real-world safety,' said Jason Kerrigan, director of UVA's Center for Applied Biomechanics. 'This is about saving thousands of lives.' The team aims to release a public database of virtual pedestrian models by 2028, which automakers worldwide can use to validate their safety systems. The initiative is part of Toyota's broader 'Mobility for All' vision, which includes a goal of zero traffic fatalities by 2050. If successful, virtual crash test dummies could become the new industry standard, shifting safety testing from the physical lab to the digital realm.
