为提高高速公路中长隧道路段运营安全水平,促使驾驶人主动降低行车速度至安全范围,对高速公路中长隧道出入口段视错觉减速标线设置参数开展研究。通过实际道路试验,采集并分析中长隧道出入口段行车速度特性及视觉特性;依据驾驶人瞳孔面积变化速率与视觉障碍的表征关系,得到驶入及驶出隧道时基于视觉感受最佳的期望车速值;分别建立隧道入口段顺鱼刺形减速标线设置参数模型和隧道出口段梳齿形减速标线设置参数模型,选取典型初始速度及最佳期望车速检验模型效果。研究结果表明,驶入和驶出隧道时,最佳期望车速分别为50 km/h和60 km/h;基于模型计算,获得隧道入口段3种鱼刺形减速标线设置参数和出口段1种梳齿型减速标线设置参数。

英文摘要：

In order to improve the level of operation safety in freeway medium-long tunnel,and impel the driver to slow down the speed to a safe range,parameters were studied for setting optical illusion deceleration markings in the entrance and exit section of freeway medium-long tunnel. Real-vehicle experiments were carried out. Data on driving speed in the entrance and exit of highway medium-long tunnel as well as driver s＇ visual characteristics were collected and analyzed. A relationship between variation rate of driver＇s pupil area and visual disturbance was found. According to the relationship,an expected speed of entering and exiting the tunnel based on best visual feelings was obtained. Parameter calculation models were built for chevron markings in the tunnel entrance section and comb tooth markings in the tunnel exit section.The model parameters were examined according to the typical initial speed as well as the expected speed.The results show the best expectation speed for entering is 50 km / h and that for leaving is 60 km / h. Three setting parameters were obtained by means of model calculation for three types of chevron markings in entrance section and one comb tooth markings in exit section.
