Virtual driving trials to assist road sign design: a case study of Ohashi junction

This paper describes the components of a virtual reality (VR) driving simulation system and its application to the design of a tunneled highway junction in Tokyo, Japan. The simulator allows for road and transport plans to be experienced from a driver’s perspective in a real-time 3D environment. User behavior information extracted from the virtual driving scenarios is used to assist design. Here we will consider the effectiveness of the VR tool for the safety assessment and design of signage and road markings for the Ohashi Junction project.
