Abstract
When the driver of the expressway enters the tunnel, if the entrance lighting brightness settings unreasonable, the driver experienced drastic changes from the high-brightness environment outside the tunnel to the low-brightness environment in the tunnel, easily lead to driver visual obstacles, so that the driver can not see the front road conditions, which is leading to the tunnel entrance more major traffic accidents. Ten typical highway tunnels with a speed limit of 60 km/h in the mountainous area is used as the test environment. Using the experimental equipment such as illuminometer and eye tracker, the driving factors of the small passenger car are collected and analyzed. Acquisition and analysis data of the change rate of pupil of the car driver under the the different luminance reduction coefficient (inside and outside the tunnel brightness ratio).Regression model is developed and according to the safety threshold, changing rate of pupil was 20%, we can obtain the safety luminance reduction coefficient, expressway tunnel luminance reduction coefficient standard with a speed limit of 60 km/h was 0.031. This is higher than Chinese standard. The conclusion of the study is of reference value to the theory and practice of highway entrance lighting design and operation management.
