– Hwarang-ro, Nowon-gu selected as the first smart intersection pilot district built by Seoul Metropolitan Government
– Collecting information by combining advanced technologies such as artificial intelligence (AI) CCTV and LIDAR, and operating signals flexibly according to traffic conditions
– Expected to relieve traffic congestion on Hwarang Road by providing cutting-edge traffic signal information through scientific signal operation
□ In downtown Seoul, high-tech intersections that incorporate scientific technologies such as big data, deep learning video information, and even 'LIDAR' applied to autonomous driving will appear within this year.
□ The Seoul Metropolitan Government announced that it would pilot the "Smart Intersection Construction Project" to relieve traffic congestion in the northeast region. The area of Taereung, Hwarang-ro, Nowon-gu, which is a habitually congested area and where traffic demand is continuously increasing, was selected as the first pilot district in Seoul.
□ 'Smart Intersection' is an intelligent traffic system that extracts various information (traffic volume, speed, unexpected situations, etc.) of an intersection and calculates the optimal signal based on the generated big data and reflects it to the signal cycle, improving vehicle congestion and traffic flow. effective for
□ The smart intersection operation method consists of a process of adjusting the signal time in real time by calculating the optimal signal operation after collecting big data information. State-of-the-art systems such as artificial intelligence (AI) CCTV that recognizes objects and lidar detectors, which are also introduced for self-driving cars, are applied to extract traffic volume, speed, and unexpected situation information by situation. After calculating the optimal signal operation time for each, we plan to apply it to the pilot district in cooperation with the Seoul National Police Agency.
□ As a result, it is expected that the inconvenience of drivers who had to wait for uniform signal times in areas with high traffic congestion and high demand will be resolved. In particular, as the first pilot project site was selected as the first pilot project site, Hwarang-ro area, where congestion is habitually caused by vehicles entering and exiting the clock and vehicles entering and exiting the Dongbu Arterial Road and the Northern Arterial Road, flexible signal operation is possible through the establishment of a customized signal infrastructure. expected to be broken
○ Hwarang-ro is a major arterial road in the Northeast region, and the section between the east side of Wolleunggyo and the intersection of Hwarangdae is highly congested. In addition, traffic congestion is expected to continue in the future as traffic demand continues to increase due to large-scale housing site development in the surrounding area.
□ As the optimal signal time considering the traffic pattern characteristics of the Hwarang-ro area is reflected, various expected effects are expected to occur. It is expected that the use efficiency of the intersection will be improved by reducing the waiting time for each vehicle and increasing the number of passing vehicles per signal.
○ Reduce the signal time in the direction with less traffic, and adjust the traffic flow by more flexibly operating the signal toward the intersection where traffic congestion occurs due to high traffic volume.
□ In addition, by utilizing the collected big data, various traffic operation indicators (traffic volume by vehicle type and lane, service level, etc.) can be calculated and used for policies. there is.
□ Meanwhile, the city plans to push for pilot operation within the year by finalizing the selection of operators in June and completing construction in the second half of the year. In addition, to analyze the implementation effect of the project, the traffic volume and speed before and after the construction of the smart intersection will be compared to quantitatively suggest how much traffic congestion is resolved.
□ Yoon Jong-jang, head of the Seoul Metropolitan Transportation Office, said, “I hope that this pilot project will provide a groundbreaking strategy for relieving traffic congestion. We will do our best to make it possible,” he said.
