ATDM轨迹验证项目开发了一个验证框架和一个轨迹计算引擎，用于比较与验证仿真车辆轨迹及动力学特性与实测车辆轨迹及动力学特性。现场数据被用于演示如何利用实地布设的仪器化车辆数据，结合该验证框架对仿真车辆动力学特性进行验证。车辆轨迹数据是在主动交通需求管理（ATDM）轨迹级验证项目的另一项任务中独立采集的。本项目的主要目标是建立一种在轨迹层面验证仿真车辆动力学特性的方法。基于轨迹数据计算了微观与宏观性能指标，并将其应用于多项验证测试中，涵盖安全性、车辆运行限值、驾驶员舒适度以及交通流等方面。

The ATDM Trajectory Validation project developed a validation framework and a trajectory computational engine to compare and validate simulated and observed vehicle trajectories and dynamics. The field data were used to demonstrate how on-site instrumented vehicle data can be used to validate simulated vehicle dynamics using the validation framework. The vehicle trajectory data were collected in a separate task of the Active Transportation Demand Management (ATDM) Trajectory Level Validation project. The primary project objective was to develop a methodology to validate simulated vehicle dynamics at the trajectory level. Microscopic and macroscopic performance measures were calculated from the trajectory data and used in a number of validation tests related to safety, vehicle limits, driver comfort levels, and traffic flow
