Changwon City Reduces Unnecessary Signal Waiting... Operates Responsive Signals on Outskirts Roads

Selection of 20 Locations Mainly in City Outskirts

Changwon City, Gyeongnam Province, will expand the operation of 'left-turn responsive signals.'

[Asia Economy Yeongnam Reporting Headquarters Reporter Park Saeyan] Changwon City in Gyeongnam announced on the 25th that the expansion of left-turn responsive signals on outer roads with low pedestrian or left-turn traffic and high straight-through vehicle traffic has greatly improved vehicle flow.

The left-turn responsive signals currently in operation were established at 20 locations last December as part of the Ministry of Land, Infrastructure and Transport's 'Intelligent Transportation System Contest Project.' Additionally, 10 smart intersections, 4 road variable message signs (VMS), and 20 traffic control CCTVs were installed.

The targets for responsive signal installation were 20 locations mainly in the outskirts of the city, where traffic volume is relatively low but frequent vehicle stops due to traffic lights and frequent signal violations occur.

According to the effect evaluation after installation, on weekdays at Jukgok-ro, green light time increased by 40.311 seconds per day (from 39.892 seconds/day to 80.203 seconds/day), and travel time on Jinbuk Industrial-ro during off-peak weekend hours decreased by 147 seconds (from 272 seconds to 125 seconds).

At the STX Samgeori intersection on weekdays, stop delay per vehicle decreased by 3.5 seconds (from 4.3 seconds/vehicle to 0.8 seconds/vehicle), and signal violations at the Sinchon Nonggongdanji intersection in Jinbuk-myeon decreased by 20 cases per hour (from 63 cases/hour to 43 cases/hour).
