摘要
针对城市水下特长隧道中部光环境单调,缺乏视觉刺激,易导致驾驶员速度感减弱和驾驶疲劳,进而产生驾驶绩效下降的问题,提出基于多频信息的城市水下特长隧道中部光环境优化设计方法,通过室内仿真试验,以速度错觉程度和反应时间为评价指标对优化设计方法进行评价.结果表明,驾驶员驾驶疲劳受行车时间和隧道视觉环境共同影响;优化设计方法使驾驶员速度错觉程度较优化前降低1.80%~8.91%,反应时间减少0.06~1.21 s,可有效提高驾驶员的速度感知能力和缓解驾驶疲劳效应.
In order to solve the problems of monotonous light environment,lack of visual stimulation,weakening of driver’s speed sense,driving fatigue and driving performance degradation in the middle of extra-long urban subaqueous tunnel,a multi-frequency information-based optimization design method for light environment in the middle of extra-long urban subaqueous tunnel was proposed.Through indoor simulation tests,the optimal design method was evaluated by taking the degree of speed illusion and reaction time as evaluation indexes.The results show that driver fatigue is affected by both driving time and tunnel visual environment.The optimal design method reduces the driver’s speed illusion by 1.80%~8.91%and reaction time by 0.06~1.21 s compared with that before optimization,which can effectively improve the driver’s speed perception ability and alleviate the driving fatigue effect.
