【摘要】：本文是2012年国家自然科学基金项目(项目编号:51178299)——“基于高动态图像技术的城市立交桥照明安全研究”的第三阶段研究内容。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。通过各地立交桥类型统计,得出了最典型的三种立交桥类型,分别为分离式立交桥、苜蓿叶式立交桥和半定向式立交桥。通过实地调研、计算机模拟和主观评价确定出立交桥各部分道路失能眩光的评价指标为阈值增量TI和眩光值GR。实地调研选定了天津、北京、武汉、邯郸、郑州、重庆、成都、上海等八座国内立交桥较多的城市。运用高动态范围图像技术对8个城市中17座立交桥的34个测试点位进行道路光度参数测量,通过计算得出每个点位的阈值增量TI值和眩光值GR值。本文采用DIALux照明设计软件主要针对半定向式立交桥进行了计算机模拟,结合本课题上一阶段研究成果对苜蓿叶式立交桥的模拟,基本完成了三种典型形式立交桥的参数模型构建。模拟结果表明,在满足立交桥道路照明标准的前提下,TI值和GR值均大于普通道路眩光标准值。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。
[Abstract]:This paper is the third phase of the 2012 National Natural Science Foundation Project (item number: 51178299), "study on Lighting Safety of Urban Interchange based on High dynamic Image Technology". Urban flyovers usually use high-rod lighting to solve the problem of night traffic. The multi-level three-dimensional space structure can realize the continuous multi-direction driving of vehicles, which plays an important role in alleviating traffic pressure. However, there is still a lack of relevant research on glare evaluation index of lighting loss of overpass. The purpose of this paper is to put forward the evaluation index and its limit value suitable for the glare of the overpass road in China, which will be of great significance to the night driving safety of the overpass road. According to the statistics of the type of overpass, the most typical three types of overpass are divided, alfalfa leaf overpass and semi-directional overpass. Through field investigation, computer simulation and subjective evaluation, the evaluation indexes of road disabling glare in different parts of overpass are determined as threshold increment TI and glare value GR.. Tianjin, Beijing, Wuhan, Handan, Zhengzhou, Chongqing, Chengdu, Shanghai, etc. The high dynamic range image technique was used to measure the road luminosity parameters at 34 test points of 17 overpasses in 8 cities. The threshold increment TI value and glare value GR value of each point were calculated. In this paper, the DIALux lighting design software is used to simulate the semi-directional overpass, and the alfalfa leaf overpass is simulated with the research results of the last stage of this paper. The parameter model of three typical overpasses has been built. The simulation results show that the TI value and the GR value are higher than those of the ordinary road glare standard on the premise of meeting the road lighting standard of the overpass. In view of the fact that the TI,GR value is generally higher than the standard value in the field measurement and simulation, the semantic difference method is used to study the subjective evaluation of the lighting scenes of 34 overpass bridges. The results show that both TI and GR are highly correlated with subjective evaluation of disability glare perception, which indicates that both threshold increment and glare value can be used as indicators for evaluating disability glare of high rod lighting mode of overpass road. In the main line and across line, the threshold increment TI is suitable to evaluate the glare loss, while the glare value GR is more suitable for the ramp.
