CityTrajBench: A Unified Benchmark for City-Scale Vehicle Trajectory Generation
Researchers introduce CityTrajBench, a unified benchmark framework for evaluating vehicle trajectory generation models across urban environments. The framework standardizes datasets, preprocessing, and evaluation metrics to enable fair comparison of statistical, VAE, GAN, diffusion, and flow-matching models, revealing that no single approach dominates all quality criteria.
