Supplementary material for the paper: Alam, M. S., & Wang, Z., & Zhang, L., & Bazilinskyy, P. (2026) "Exploring Veo 3's Capabilities for Generating Urban Traffic Scenes in 76 Cities Worldwide". Adjunct Proceedings of the 18th International Conference on Automotive User Interfaces and Interactive Vehicular Applications (AutoUI). Gothenburg, Sweden. https://doi.org/10.1145/3828158.3838250 This study explores the potential of Google Veo 3, a generative video model, to synthesise 8-second dashcam-style urban traffic scenes based solely on text prompts in 76 cities across six continents. YOLOv11x was used to count road users, traffic lights, and stop signs, revealing variations across cities: Karachi had the most objects detected (79), while Muscat had only four cars. Audio analysis using dBFS showed that Montevideo was the loudest, while Copenhagen was the quietest. Through a qualitative visual analysis, the authors assessed and confirmed the perceived authenticity of most traffic scenes and highlighted AI errors, including the inability to handle non-English languages in these videos. Moreover, we compared 10 synthetic videos of New York City and Kampala, each, and verified that Veo …
