立交桥高杆照明干扰光与TI值研究

Study on the Obtrusive Light and TI Value of Urban Intercgange Illuminating

本文依据国际照明委员会CIE技术报告和国内外城市机动车道路照明质量标准,总结出我国立交桥照明质量评价的技术指标。通过对天津市和北京市共8座立交桥高杆照明的现状进行调研、计算,并采用专业照明模拟计算软件Ulysee进行计算、模拟,探讨了TI在立交桥的适用性。本文探讨了用TI来计算、评价我国立交桥失能眩光的重要方法,并通过对测量计算的数据、现场体验、主观评价、软件模拟计算研究结果的分析,提出了适用于我国立交桥的TI参数建议值。

According to CIE technical reports and consult lighting quantity standards of domestic urban motorways and international urban motorways, the paper summarized technical index on evaluating lighting quantity of our country cloverleaf. The paper certificated that TI is applicable to cloverleaf by investigating and computing high-pole lighting facilities in accordance with the present situation of cloverleaves in Tianjin and in Beijing, as well as by adopting professional lighting software Ulysee to simulate and compute. The paper discussed on the important method firstly in which applied TI parameter which CIE recommends to compute and evaluate disability glare, and to put forward the recommended value of TI applicable to our country cloverleaves by measuring data, subjective evaluation, lighting simulation software.
