摘要：
Glare screen barrier is an important element in highway safety engineering. Height and spacing of glare screen barrier block are important parameters in highway design, since vehicles of different driver eye heights with different head light heights are plying on highways. Selection of spacing of glare block is a complex problem. A model has been proposed to determine optimum spacing of glare block for horizontal alignment. Glare block can be placed perpendicular to the road or inclined by a certain angle to obtain optimum cost. It is found that spacing is optimal when the sum of inclination angle(x) and degree of curvature (theta) is 70 degrees; i. e., x+theta = 70 degrees.
