南昌市一环路交通指路标志系统优化方案研究

南昌市一环路于2019年成环通车，是南昌市的第一条快速路环线。在分段建设过程中，各建设单位只限于对施工范围内的道路指路信息进行设计和建设，造成一环路成环后指路标志缺乏系统性、连续性，还存在部分路段采用的指路标志等级与道路等级不符等问题。通过分析现状南昌市一环路交通指路标志设置杂乱症结，探索既满足国标又符合南昌市交通发展需要的一环路交通指路标志系统优化方案，为南昌市新建或改建的城市快速路交通指路标志设计提供有益参考。

Research on Optimization Scheme of Traffic Guide Sign System for Ring I Road in Nanchang City

The Ring I Road of Nanchang City is the first expressway ring line of Nanchang, and was opened to traffic in 2019. In the process of subsection construction, each construction unit is limited to the design and construction of the road guidance information within the construction scope, which results in the lack of systematicness and continuity of the guidance signs after Ring I Road is formed, as well as the grade of guide signs inconsistent with the grade of roads used in some road sections. Through the analysis of the current situation, the traffic guide sings of Ring I Road in Nanchang are set up in disorder. The optimization scheme of traffic guide sign system for Ring I Road not only meeting the national standards, but also conforming to the traffic development demand of Nanchang is explored in order to provide the beneficial reference for the design of the traffic guide signs of the newly built or reconstructed urban expressways in Nanchang.
