基于Ecotect的T型交叉路口布灯方式仿真分析

为研究灯具布置对T型交叉口的照明影响,通过采用照明仿真软件对T型交叉口的交错式、对称式及中心对称式3种布灯方案进行仿真模拟分析,得到了不同布灯方式下的照明强度。结果表明:在相同灯具及条件下,交错式布灯方案最优,但道路终端灯光光强设置需偏大;对称式方案效果次之,交叉口中心位置照度低;中心对称式集中照明效果最好,但相比交错式及对称试其经济能耗最大。通过照明仿真模拟分析,有效验证了交错式布灯方案在T型交叉口照明设计中的优越性。

Simulation Analysis of T-intersection Light Distribution Mode Based on Ecotect

In order to study the influence of lamp arrangement on the lighting of T-type intersection,this paper uses ecotect lighting simulation software to simulate and analyze three kinds of light distribution schemes of T-type intersection,i.e.staggered,symmetrical and central symmetrical,and obtains the lighting intensity under different light distribution modes.The results show that:under the same lamps and conditions,the staggered light distribution scheme is the best,but the light intensity setting at the road terminal needs to be larger;the effect of the symmetrical scheme is the second,the illuminance at the center of the intersection is low;the effect of the central symmetrical centralized lighting is the best,but the energy consumption is the largest compared with the staggered and symmetrical test.Through the simulation and analysis of lighting,the superiority of staggered layout scheme in T-intersection lighting design is effectively verified.
