城市道路指路标志信息选取方法研究

为了科学、合理地设置指路标志系统，给道路使用者提供准确、及时和有效的指路标志信息，在设计方面确定了合适的服务对象，对城市的主要交通吸引点、路网结构及交通功能等进行了调查分析，并在此基础上建立了指路标志信息要素分级体系和指路标志信息选用技术准则．研究结果表明：指路标志信息选取需要考虑的因素众多，并注重对区域土地利用、路网结构、交通功能及交通运作等进行调查与分析．只有以此为基础，才能保证所选指路标志信息的准确性、合理性和系统性，确保指路标志系统发挥正常的引导功能．

Research on selection method of the urban road directional sign information

In order to set up a reasonable directional sign system,and provide accurate, timely and effective directional sign information to the road users,a suitable serving object is identified for design, and the major traffic attract-points, road network structure and traffic functions of the city are investigated. Afterwards, the classification system of directional sign information element and the technology criteria of directional sign information selection are set up. The results show that there were many factors are considered as directional sign information selection, so it focus on the investigation and analysis of the regional land use,road network structure, traffic functions and traffic operations, the veracity, rationality and systematic of the directional sign information were selected, accordingly, the directional sign system is ensured to play the normal guiding function.
