Abstract: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.
