Tunnel Traffic Facilities and Landscape Evaluation Technology Based on Virtual Reality

摘要:

针对隧道行车存在空间封闭、照度低、风险高、难以开展实地测试的问题，应用自适应控制系统模型（ACT-R）对隧道内汽车驾驶的认知和操控行为建模，应用虚拟现实技术建立三维隧道及相关交通设施和环境模型，并结合SCANeRTM studio驾驶模拟舱建立基于虚拟现实的隧道仿真驾驶测试环境；其次，通过实验验证了基于虚拟现实的隧道交通设施和环境评估技术可行，实验结果证明隧道内道钉、轮廓标、反光环3种交通设施可提高驾驶员的驾驶视野，有效缓解隧道驾驶压抑感，让驾驶员以更轻松的精神状态行车，进而提高隧道内的行车安全。

Abstract:

According to the problems of space closure, low illumination and high diving risk in tunnel, the cognitive model (namely ACT-R) was introduced to model the cognitive and action in the cognition and control behavior of vehicle driving in tunnel, and the virtual reality technology was used to establish 3D tunnel and its related traffic facilities and landscape model. Secondly, combined with SCANeRTM studio cockpit, a virtual reality (VR) tunnel driving test environment was established. The feasibility of tunnel traffic facilities and landscape evaluation technology based on virtual augmented reality was verified by experiments. It is proved by experiment that track spike, contour mark and tunnel reflector, can improve the field of driver’s vision, relieve the driving pressure in the tunnel, and make the driver drive in a more relaxed state. As a result, they can improve the safety of driving in the tunnel.
