Applying AI to Traffic Signals... "Vehicle Traffic Improved by 13%"

AI Proposes Traffic Volume Analysis and Traffic Signal Optimization
Applied to Hwaseong City's Chronic Congestion Zones, Reducing Time by About 13%
Accurate Traffic Volume Measurement Possible 365 Days a Year

By integrating AI (artificial intelligence) technology with communication location data and applying it to actual traffic signal systems, results showed not only a reduction in vehicle travel time but also a decrease in carbon emissions. On the 26th, SK Telecom announced, "We recently developed a traffic signal optimization solution (T.Flow) based on traffic data analysis extracted from our AI-based location data analysis platform (LITMUS) and applied it for the first time to habitual congestion areas in Hwaseong City, achieving meaningful results such as reduced vehicle travel time." The location-based data analysis platform ‘LITMUS’ is a technology where AI analyzes communication base station location data to provide intelligent location data such as movement status and means of transportation.

The traffic signal optimization solution ‘T.Flow’ analyzes traffic signals and provides an optimal signal system by using directional traffic volume information at intersections extracted through location-based mobile communication data analysis. SKT collaborated with Hwaseong City, Hwaseong Dongtan Police Station, Hwaseong Western Police Station, and the Road Traffic Authority to create signal system improvement plans for 15 intersections in habitual congestion areas over three months starting in March and tested the traffic improvement effects. The actual vehicle travel time was reduced by 13%, cutting about 1 minute and 40 seconds.

This corresponds to an economic benefit of 1.2 billion KRW annually and a reduction of 52 tons of carbon emissions. If expanded to the entire Hwaseong City in the future, it is expected to yield an annual economic benefit of approximately 52 billion KRW and reduce carbon emissions by about 2,200 tons. Shin Yong-sik, Head of SKT Connectivity CO, stated, “According to the Korea Transport Institute, the nationwide traffic congestion cost in 2018 was estimated to be about 68 trillion KRW,” adding, “We will actively utilize advanced ICT technology to take the lead in solving the increasingly serious urban traffic problems and fulfill our social responsibility as the nation’s number one mobile carrier.”
