摘要
山区高速公路尽管在设计上尽量减少曲折路段与起伏路段,依然存在大量起伏与蜿蜒,易造成严重事故危害。从行车安全角度出发进行山区高速公路观景台设计与高速公路中央隔离带防眩植株配置设计。首先进行观景台配置要素考虑,然后根据该路段交通流量等实际因素,模拟了观景台平面设计,为司机提供优美景色缓解视觉疲劳;针对高速公路中央隔离带,给出了中央隔离带防眩植株高度与间距计算方法,并确立植株高度为1.6m,以防在夜间会车时产生视觉眩光,发生交通事故。
Despite minimizing winding and undulating sections in design,mountainous expressways still have a large number of undulating and winding sections,which are liable to cause serious accident hazards.From the point of view of traffic safety,the design of Mountainous Expressway viewing platform and the design of anti-glare plant configuration of Expressway Central isolation zone are carried out.Firstly,the layout elements of the viewing platform are considered,and then the plane design of the viewing platform is simulated according to the actual factors such as traffic flow in the section,which can provide beautiful scenery for drivers to alleviate visual fatigue.Aiming at the central isolation zone of expressway,the calculation method of the height and spacing of the anti-glare plant in the central isolation zone is given,and the height of the plant is established to be 1.6m,so as to prevent the visual glare from occurring during the night traffic meeting.A traffic accident happened.
