TravelEval: A Comprehensive Benchmarking Framework for Evaluating LLM-Powered Travel Planning Agents

TravelEval addresses three key limitations of existing travel planning benchmarks: overemphasis on constraint compliance, lack of real-world authenticity, and isolated daily plan assessments. The benchmark features a six-dimensional evaluation framework that assesses plans across accuracy, compliance, temporality, spatiality, economy, and utility. It includes a highly realistic data sandbox with precise accommodation pricing and authentic intercity transportation data. A simulation-based global evaluation method emulates complete travel plans using API-integrated geographic information and fine-grained queuing time. The authors evaluated 12 mainstream approaches with TravelEval, revealing significant gaps in current LLM-based travel planning agents. The paper is available on arXiv under identifier 2606.01046.
