Expressway exit curved slope ramp sight line induction system
The invention relates to the technical field of traffic safety of expressways, in particular to an expressway exit curved slope ramp sight induction system, which is characterized in that corresponding first-stage, second-stage and third-stage sight induction systems are respectively arranged in road section areas with speed limits of 40km/h and below, 40-60km/h and 60km/h and above; the sight line induction system comprises a high-frequency rectangular attached delineator arranged at the bottom of the guardrail, a medium-frequency combined rectangular attached delineator arranged in the middle of the guardrail and a medium-frequency warning linear induction mark arranged on the outer side of the guardrail, and the high-frequency rectangular attached delineator, the medium-frequency combined rectangular attached delineator and the medium-frequency warning linear induction mark are graded according to different speeds. The round delineators, the rectangular attached delineators and thevisual reference columns are arranged on the inner sides and the upper portions of the guardrails, so that delineator induction of a curved slope section can be improved, the sensing capacity of a driver to a curve and a longitudinal slope is enhanced, the driver is effectively warned, and the starting section, the middle portion and the ending section of the ramp are each provided with an annularlight reflection structure. And a lane indicator is arranged below the annular reflective structure so as to ensure that a driver can discover within a decision sight distance.
本发明涉及高速公路的交通安全技术领域，特指一种高速公路出口弯坡匝道视线诱导系统，对于限速40km/h及以下、40～60km/h、60km/h及以上三种速度的路段区域，分别设置对应的一级、二级以及三级视线诱导系统，视线诱导系统包括在护栏底部设置高频矩形附着式轮廓标，在护栏中部设置中频组合式矩形附着式轮廓标，在护栏外侧设置中频的警示型线形诱导标，并根据不同的速度分级，在护栏内侧及上方设置圆形轮廓标、矩形附着式轮廓标以及视觉参照柱，可以提高对弯坡路段的轮廓诱导，增强驾驶人对弯道和纵坡的感知能力，有效地警示驾驶人，在匝道的起始段、中部和结束段均设置一道环形反光构造物，并在环形反光构造物下方设置车道指示器，以确保驾驶人能够在决策视距内发现。
