摘　　要：公路交通标志是引导车流、组织交通的重要设施,对于保障交通运输具有重大意义。以行车人员标志信息获取角度出发,建立了标志视认模型并给出认读距离、反应距离及行动距离等基本模型参数,并以消失距离理论为基础给出交通标志位置确定方法及各类型交通标志的支撑方式,以定量分析方式给出立柱(横梁)、基础等结构的验算及优化设计方法,可为交通标志设计提供借鉴。Highway traffic sign is an important facility to guide traffic flow and organize traffic,which is of great significance to ensure transportation.A sign recognition model is established from the perspective of driver sign information acquisition,and basic model parameters such as reading distance,reaction distance and action distance are given.Based on the disappearance distance theory,the location determination method of traffic signs and the supporting mode of each type of traffic signs are given.The checking calculation and optimization design method of column(beam),foundation and other structures are given by quantitative analysis,which can provide reference for traffic sign design.
