摘要
立交桥照明阈值增量测点选择研究是立交桥道路照明安全性研究的基础内容,也是关键内容。道路照明标准中,阈值增量是衡量道路照明安全的重要因素。通过对标准中阈值增量计算公式进行数学分析,以及结合立交桥自身的道路特点,总结出适合立交桥照明阈值增量测量的测点,使所得的阈值增量TI值更具有有效性和适应性。
The research on locating measurement of threshold increments of interchange lighting is the basic and important content of the safety research of the road lighting of interchange. In the road lighting standard, threshold increments are the important factors of measuring the lighting safety of road. Based on mathematical analysis on the formula of threshold increments, and considering the characteristics of interchange, we can sum up and find out measurement locations of an interchange threshold increments, so that the TI will be more effective and proper.
