Sejong City is promoting a complete overhaul of the urban signal system.
The city announced on the 30th that it recently conducted a research project applying time-based variable signal cycles to major road sections within the city center.
The research project, aimed at resolving traffic congestion during peak commuting hours as part of traffic innovation measures, was carried out by the Korea Road Traffic Authority's Daejeon-Sejong-Chungnam branch over six months starting from October last year.
The core of the research project was to analyze the effects observed when signal coordination and synchronization methods were experimentally applied to major roads in the jurisdiction with concentrated traffic volumes, such as Hannuri-daero and Jeoljae-ro.
As a result, it was confirmed that applying time-based variable signal cycles improves delay time by 34% and vehicle stop rate by 51.7%, respectively.
Based on these effects, the city plans to conduct an additional signal system optimization research project this year to understand the impact on overall urban vehicle flow when expanding time-based signal cycles and intersection signal synchronization, and to find ways to maximize the effects.
Furthermore, based on the research results, the city will promote a plan to expand and apply time-based signal cycles and intersection signal synchronization to all intersections within the city center.
Along with this, a detailed plan will be established to verify the reliability of the online signal control system for rapid response to sudden vehicle congestion at major intersections and to ensure data security.
Mayor Choi Min-ho of Sejong City said, “We will review whether there are any additional areas that need improvement to alleviate citizen inconvenience caused by vehicle congestion and carefully address even minor inconveniences to improve them.”
