VIRES 的 Virtual Test Drive 产品（VTD）为工程师提供了进行自动驾驶仿真所需的所有要素，同时，VTD不仅兼容 MSC 软件的内部技术，而且兼容许多第三方软件。

举例来说，VTD 不仅提供了两种不同的用来表征车辆动力学的嵌入式技术（具有不同的仿真速度和结果准确度），还能与 Adams Car（车辆动力学仿真的事实标准）或其他任何车辆动力学软件共同使用。VTD 的交通模型也毫不逊色：VTD 具备业内最全面的交通仿真能力（可根据多个参数来设置每辆车的驾驶风格，必要时可同时仿真数千辆车）；但也可以将其他交通模型整合到 VTD 中，例如 SUMO。

VTD provides a modular tool-set for road generation, scenario definition, traffic and sound simulation, simulation control, image generation etc. It uses established standard file formats.

Smart Autonomous Mobility Enable. Accelerate. Deploy.

Enabling customers of all types and sizes to accelerate and deploy a bold autonomous mobility vision.

Virtual testing is of the most vital importance to autonomous vehicle development, since the autonomous system itself needs to run through billions of miles of virtual road testing or real road testing to ensure SAE level 5 safety requirements. As road network simulation is an essential part of any virtual testing environment, the ability to create and share billions of miles of road network data becomes ever more critical.
