Improvement Design about Anti-Dazzling of Mid-Barriers on Multilane Highway in Urban Fringes of China

Abstract:

Most multilane highways in urban fringes of China separate vehicles from the other direction by the use of mid-barriers, which failed to prevent from dazzling at night .This research proposes the design methods of anti-dazzling on the mid-barriers with the basic principle of anti-dazzling. The multilane highway with 4 lanes which sets mid-barriers in urban fringes is used as a case of application, three schemes are set to compare their advantages and disadvantages by analyzing the shielding area and the bending moment of wind load, the result shows the anti-dazzling improvement of Scheme 1 increases 108%, Scheme 2 increases 102%,while the bending moment of wind load of Scheme 1 increases 59.6%, Scheme 2 increases 66.4%. So, the recommended design is Scheme 1.
