摘要
针对目前数据采集技术效率低,劳动强度大,评价可靠性不高的缺陷,提出采用基于数据可视化的地理信息系统公路安全评价方法,通过对GIS三维模型后续视线分析确定障碍物位置及形式,提示进行实地考察验证,经验证,分析期间检测到的障碍物与现场考察的位置一致性较传统方法有所提高,表明了该方法的可行性及应用潜力。
According to the data collection technique with the low efficiency, the great labor intensity and low evaluation reliability, the paper points out the safety evaluation methods of the GIS based on data visualization, proves the site observation by identifying the location and forms of the barriers of the follow-up sight line of GIS three-dimension model, and proves that the consistency of the barriers tested during the analysis pe-riod and the location of the site observation is improved, and indicates the feasibility of the method and its application potential.
