摘要
视距不良问题是我国高等级公路运营安全的潜在威胁。小客车视距位置不良主要在于车辆在超车道行驶时中分带防眩设施对视距的遮挡。大货车视距主要遮挡来自于曲线内侧的路堑边坡。隧道内行驶视距与车辆行驶速度和隧道线性有关。
The problem of bad sight distance has been a potential threat to highway safe operation. Car＇s bad viewing position mainly lies in the occlusion of median separator＇s anti-dazzle facilities to the sight distance when going in the overtaking lane. The main occlusion to truck sight distance comes from the cutting slope in the inner side of the curve. Driving range in the tunnel is related with vehicle speed and tunnel liner.
