Researchers have introduced CityTrajBench, a unified framework designed to standardize the evaluation of urban vehicle trajectory generation methods. This benchmark addresses the fragmentation in existing studies by providing a common protocol for data processing, model adaptation, and multi-level evaluation. Experiments using CityTrajBench revealed that different model families excel in specific areas, such as geometric fidelity or realism, indicating that urban trajectory generation is a multi-objective problem with inherent trade-offs.
