Mixed Reality Transport Experiment Space for Sustainable ITS

本研究开发的“混合现实实验系统”由“虚拟实验系统”和“真实观测系统”组成。虚拟实验系统是驾驶模拟器与交通模拟器的结合，使驾驶模拟器的测试对象可以与在交通模拟器中运行的其他车辆一起行驶。利用虚拟实验系统，我们可以创造多种在现实世界中无法产生的实验交通状况，并按照我们的要求控制实验环境。根据实际观测系统的观测数据，对虚拟实验系统进行了验证。然后，该系统被用于揭示诸如高速公路和地面街道上的驾驶行为等人为因素。最后，我们对智能交通系统的应用进行了几项研究，包括(a)在交通挤塞及/或事故发生时使用肩路空间的可能性；(b)城际高速公路的挤塞机制及其应对措施；以及(c)提供路边停车位。这些应用研究是未来智能交通部署的先驱性研究。

This research develops ‘the mixed reality experiment system' which consists of ‘the virtual experiment system' and ‘the real observation system'. The virtual experiment system is a combination of a driving simulator with a traffic simulator so that a test subject of the driving simulator can travel with other vehicles running in the traffic simulator. Using the virtual experiment system, we can create several experimental traffic conditions which cannot be made in the real world and control the experimental environment as we specify. The virtual experiment system has been validated based on observed data acquired from the real observation system. The system was then used to disclose human factors such as the driving behavior on an expressway and on a surface street. Finally, several examinations on ITS applications were made such as (a) possibility of shoulder space usage during congestion and/or incidences, (b) congestion mechanism and its counter-measure for sag congestion on an intercity motorway, and (c) provision of on-street parking places. These ITS application studies seem pioneer research for our future ITS deployment.
