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“真实观察系统”组成。虚拟实验系统是驾驶模拟器和交通模拟器的组合，使得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，我们可以创造出一些真实世界中无法创造的实验交通条件，并按照我们指定的方式对实验环境进行控制。基于实际观测系统采集的观测数据，对虚拟实验系统进行了验证。然后，该系统被用来揭示人的因素，如在高速公路和地面街道上的驾驶行为。最后，对其应用进行了几个方面的研究，例如：(A)在拥堵和/或事故期间使用路肩空间的可能性；(B)城际高速公路上凹陷拥堵的机制及其对策；以及(C)提供路边停车位。这些ITS应用研究似乎是对我们未来ITS部署的开拓性研究。

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.
