摘　　要：城市立交桥多采用高杆照明方式解决夜间通行问题,其多层次的立体空间结构可以实现车辆的连续多方向行驶,对缓解交通压力起到了重要作用。但目前仍缺乏针对立交桥照明失能眩光评价指标相关研究,本文旨在提出适合于国内立交桥道路失能眩光的评价指标及其限值,这将对立交桥道路夜间行车安全具有重要意义。针对实测和模拟中TI、GR值普遍高于标准值的情况,本文采用语义差别法对实测的34个立交桥高杆照明场景进行主观评价研究。研究结果表明,TI与GR均与主观评价失能眩光感受具有高度相关性,说明阈值增量和眩光值都可以作为立交桥道路高杆照明方式失能眩光评价指标。主线和跨线部位适宜采用阈值增量TI作为其失能眩光评价指标,而匝道部位则更适合采用眩光值GR作为其失能眩光评价指标。Urban overpass often use high mast lamp to deal with night traffic problems. Its multi-level structures allow multi-direction traffic,so it is important to ease urban traffic pressure. But domestic and foreign still lacks of research on disability glare of overpass lighting. This article put forward the evaluation index of disability glare of overpass lighting on domestic,which is significant for safe driving at night of overpass road. According to the situation that TI and GR values are generally higher than the ordinary road standard value,this paper adopts the semantic differential method based on 34 measured overpass high mast lighting scene for subjective evaluation research. The research results shown that TI and GR were highly correlated with subjective evaluation of disability glare feeling,it is said that the increment threshold and glare rating can be used as the overpass road disability glare evaluation index. TI is more suitable to evaluate main road and overline,while GR is more suitable for the ramp of overpass.
