介绍了一种新型的可控、无风险驾驶和出行行为研究平台--网络物理系统模拟器(CPSS)。CPSS的主要特点是：(1)在三维虚拟环境中模拟多用户沉浸式驾驶；(2)基于专用中间件的交通通信模拟器与人类驾驶的集成；(3)多用户驾驶模拟器在流行的软硬件平台上的可访问性。这种功能的组合使我们能够轻松地收集有关多用户司机之间相互作用的有趣现象的大规模数据，这是当前单用户驾驶模拟器所不可能做到的。本文的核心原创性贡献有三个方面：(1)介绍了一个基于我们独创的大规模多用户网络3D虚拟环境DIVE的多用户驾驶模拟器；(2)介绍了一个模拟车与车、车与基础设施通信的中间件OpenV2X；(3)基于我们的CPSS平台，给出了两个实验。第一个实验调查的是“胶颈”现象，即一个由四名用户司机组成的队列在迎面而来的交通方向上发生了一起事故。其次，我们报告了一项关于协作式智能交通系统咨询系统有效性的试点研究。
The article introduces a novel platform for conducting controlled and risk‐free driving and traveling behavior studies, called Cyber‐Physical System Simulator (CPSS). The key features of CPSS are: (1) simulation of multiuser immersive driving in a three‐dimensional (3D) virtual environment; (2) integration of traffic and communication simulators with human driving based on dedicated middleware; and (3) accessibility of multiuser driving simulator on popular software and hardware platforms. This combination of features allows us to easily collect large‐scale data on interesting phenomena regarding the interaction between multiple user drivers, which is not possible with current single‐user driving simulators. The core original contribution of this article is threefold: (1) we introduce a multiuser driving simulator based on DiVE, our original massively multiuser networked 3D virtual environment; (2) we introduce OpenV2X, a middleware for simulating vehicle‐to‐vehicle and vehicle‐to‐infrastructure communication; and (3) we present two experiments based on our CPSS platform. The first experiment investigates the “rubbernecking” phenomenon, where a platoon of four user drivers experiences an accident in the oncoming direction of traffic. Second, we report on a pilot study about the effectiveness of a Cooperative Intelligent Transport Systems advisory system.
