本文报告了苏黎世大都市区完全分解（基于代理）交通模拟的校准和分析。基于代理的模拟超越了传统的交通模型，因为它不仅平衡路线选择，还平衡全天的出行行为，包括出发时间选择和模式选择。先前的工作表明，应用一种新颖的校准技术可以根据流量计数一次性调整所有选择维度，产生的交叉验证结果可与任何最先进的四步模型相媲美。虽然之前的研究旨在对校准方法进行方法论说明，但这项工作侧重于现实世界的场景，并详细阐述了所获得的结果对于进一步需求分析目的的有用性。
This article reports on the calibration and analysis of a fully disaggregate (agent-based) transport simulation for the metropolitan area of Zurich. The agent-based simulation goes beyond traditional transport models in that it equilibrates not only route choice but all-day travel behavior, including departure time choice and mode choice. Previous work has shown that the application of a novel calibration technique that adjusts all choice dimensions at once from traffic counts yields cross-validation results that are competitive with any state-of-the-art four-step model. While the previous study aims at a methodological illustration of the calibration method, this work focuses on the real-world scenario, and it elaborates on the usefulness of the obtained results for further demand analysis purposes.
