Title: 用于 V2X 应用开发的虚拟和真实数据填充的交叉口可视化和测试工具

Abstract: The capability afforded by Vehicle-to-Vehicle communication improves situational awareness and provides advantages for many of the traffic problems caused by reduced visibility or No-Line-of-Sight situations, being useful for both autonomous and non-autonomous driving. Additionally, with the traffic light Signal Phase and Timing and Map Datainformation and other advisory information provided with Vehicle-to-Infrastructure (V2I) communication, outcomes which benefit the driver in the long run, such as reducing fuel consumption with speed regulation or decreasing traffic congestion through optimal speed advisories, providing red light violation warning messages and intersection motion assist messages for collision-free intersection maneuvering are all made possible. However, developing applications to obtain these benefits requires an intensive development process within a lengthy testing period. Understanding the intersection better is a large part of this development process. Being able to see what information is broadcasted and how this information translates into the real world would both benefit the development of these highly useful applications and also ensure faster evaluation, when presented visually, using an easy to use and interactive tool. Moreover, recordings of this broadcasted information can be modified and used for repeated testing. Modification of the data makes it flexible and allows us to use it for a variety of testing scenarios at a virtually populated intersection. Based on this premise, this paper presents and demonstrates visualization tools to project SPaT, MAP and Basic Safety Message information into easy to read real-world based graphs. Also, it provides information about the modification of the real-world data to allow creation of a virtually populated intersection, along with the capability to also inject virtual vehicles at this intersection.

Abstract: 车辆到车辆通信所提供的能力提高了态势感知，并为许多因能见度降低或视线受阻而造成的交通问题提供了优势，这对自动驾驶和非自动驾驶都有用。 此外，通过车辆到基础设施（V2I）通信提供的交通信号相位和时间以及地图数据信息和其他建议信息，可以实现一些长期使驾驶员受益的结果，例如通过速度调节减少燃料消耗或通过最佳速度建议减少交通拥堵，提供红灯违规警告消息和交叉路口运动辅助消息以实现无碰撞的交叉路口操作都是可能的。 然而，开发这些应用以获得这些好处需要一个漫长测试周期内的密集开发过程。 更好地理解交叉路口是这一开发过程的重要组成部分。 能够看到广播的信息是什么以及这些信息如何转化为现实世界，这将有助于开发这些非常有用的应用程序，并且在使用易于使用的交互式工具呈现时也能确保更快的评估。 此外，这些广播信息的记录可以被修改并用于重复测试。 数据的修改使其具有灵活性，并允许我们将其用于虚拟人口密集的交叉路口的各种测试场景。 基于此前提，本文展示了可视化工具，将SPaT、MAP和基本安全消息信息投影到易于阅读的基于现实世界的图表中。 同时，它还提供了关于修改现实世界数据的信息，以便创建一个虚拟人口密集的交叉路口，并具备在这个交叉路口注入虚拟车辆的能力。
