It has been a year since Seoul selected two autonomous districts, Seongdong-gu and Yangcheon-gu, as “Special Smart City Zones” to solve everyday issues, such as transportation, safety, and welfare, using cutting-edge information and communications technologies including Internet of Things (IoT). Over the past year, changes took place in various fields, such as pedestrian traffic safety, car parking for the disabled, and care services for the elderly who live alone, ameliorating citizens’ experiences.
Seongdong-gu saw a nearly 70-percent decrease in the number of stop line violations after the establishment of the “smart crosswalk,” through which a variety of new-tech sensors were installed at 14 crosswalks with high risks of traffic accidents due to the large volume of pedestrians. Comparing the number of stop line violations during the two months after the installation of the “smart crosswalk” at the crosswalk in front of the Seongdong-gu Office and Muhak Girls’ High School, the number declined from 24,000 (Sep. 1-15, 2019) to 7,000 (Oct. 16-31, 2019).
Number of Stop Line Violations (Period of Operation: Sept.1-Oct.31)
At a smart crosswalk, the LED lights installed in the ground sends green and red signals to the traffic light. When a pedestrian approaches the road at a red light, an audible warning goes off.
The LED lights that illuminate the whole crosswalk enhance visibility for drivers at night. In terms of vehicles that violate the stop line or speed limit, the method that shows part of their license plate numbers and an image of the vehicles on the electronic display based on the analysis of intelligent CCTV has been preventing these types of violations.
Yangcheon-gu is providing the “protection of exclusive parking zones for the disabled” service that is effective in preventing illegal parking and stopping. Non-disabled drivers who tried to park their cars in disabled-designated parking spaces abandoned their attempts and left after hearing the voice guidance. As a result of checking 80 parking spaces reserved for the disabled (Jan. 14-30, 2020), 28% (1,016 out of 3,628 vehicles) of vehicles driven by non-disabled driver that attempted parking, left in the end.
The “protection of exclusive parking zones for the disabled” is a service that guides non-disabled drivers with a voice warning when they try to park their vehicles in a disabled-designated parking space. The service is being operated in 80 parking spaces designated for the disabled in 17 private and public parking lots, including Mok-dong 5 Danji Apartment, E-Mart (Mok-dong branch), Sinwol Culture and Sports Center, and Yangcheon Culture Center.
Other empirical services that are being commercialized in the two Special Smart City Zones include ▴ “Smart Plug” (Yangcheon-gu) for preventing lonely deaths of the elderly who live alone, ▴ “Customized Smart Security Light” (Yangcheon-gu) that automatically detects a breakdown, and ▴ “Remote Control of Facilities that Produce Air Pollutants” (Seongdong-gu) to detect whether the air-pollution prevention facility of an automobile paint shop is being operated with IoT sensors.
|Smart Street Light (Electric Charging) Service|
This year, Seoul will continue to expand the existing services of the Special Smart City Zones and also introduce two new services: ▴ “Smart School Zone,” which notifies drivers of the existence of pedestrians and pedestrians of that of running vehicles through the LED lights and ▴ “Street Light Electric Charging Service” for bikers to charge their electric bikes with the electric chargers installed on the street lamps.
