Daegu City plans to develop into a smarter Daegu by discovering and applying smart city services that citizens can sympathize with and experience to improve urban vehicle flow, expand water supply remote meter reading, and provide free Wi-Fi in shopping centers.
2.26.(Fri) Daegu City Mayor Kwon Young-jin and other city hall officers, transportation and information communication technology (ICT) experts, and Daegu National Police Agency head of the Transportation Division held a report on the progress of the Daegu Smart City and checked the progress of the smart city. do.
Smart transportation system based on artificial intelligence (AI) that returns time to citizens
Daegu City has many congested sections due to the urban structure with many commuters such as industrial complexes on the east and west axis, and the time required for commuting to commute is counted among the many special and metropolitan cities. In order to solve these urban traffic problems, intelligent CCTVs will be installed in stages at about 2023 intersections within the 4th circular line in the city by 250 and traffic information data will be collected. The goal is to optimize traffic light signal cycles by analyzing traffic information using artificial intelligence.
If the artificial intelligence (AI)-based smart transportation system is successfully established and operated, it will save tens of billions of won per year, including improving chronic traffic congestion in the city center (15%), securing pedestrian safety, and increasing leisure time due to reduced commuting time. It is expected to be able to reap.
In fact, in November 2020, as a result of a case study of the smart intersection signaling system for Daemyeong-ro in Nam-gu (Seongdang Intersection-Nam-gu Office Intersection, 3.91 km and 13 intersections), the total annual vehicle operation cost of 5 million won and time cost in the above section only. Congestion costs, including 4 billion won, and environmental costs of 24 million won were confirmed.
This project is also significant as the first case in the country to be applied on a large scale in the city center, and Daegu itself is provided to become a smart city innovation growth platform, and traffic expert advisory meeting and stakeholders are invited to successfully promote vehicle communication and pedestrian safety. Including seminars will continue to be promoted.
In addition, we plan to actively participate in local companies to build infrastructure, analyze data, verify simulators, and improve the traffic signal system to grow into a platform company and support them to advance beyond the region, with related organizations such as Daegu National Police Agency and Road Traffic Authority. It is also planning to promote organic cooperation.
Real-time information collection and free Wi-Fi provided through the Daegu One network
It is essential for smart cities to have an information and communication infrastructure in order to collect various information generated in the city in real time, but it is not possible to collect and analyze scattered information and communication sensor information in an integrated manner.
The Daegu One Network, which is being promoted by Daegu City, collects, stores, processes, and analyzes various information generated in the city to support policies and decision-making that the city needs, and communicates through digital transformation and connection of urban infrastructure. In addition to cost reduction, it is planning to promote the Daegu Smart City, which provides public services and creates business models for companies.
To this end, Daegu City plans to build an Internet of Things (IoT) service network all over Daegu by 2023 using its existing self-optic communication network, and complete a triple dense network with shared WiFi.
The triple-medium network is expected to provide information required by citizens by installing base stations in public buildings owned by Daegu City in stages, making remote water meter readings, environment, security, and parking maps, and enabling Daegu City's policy decisions.
In the long term, remote meter reading of water supply will be accommodated for 30 coins, and it will be additionally used for leak detection, transparent charge imposition, and monitoring of water consumption for the elderly alone. In addition, it is possible to reduce the stress of searching for parking spaces by providing real-time parking information on the street, and to quickly respond to preliminary inspections and repairs such as alleyway security to prevent civil safety accidents.
In addition, a movement to establish a shared WiFi living lab is being conducted for local shopping malls. Starting with Dongseong-ro and university districts, we will create a shared WiFi platform in which 2023 shopping centers in 50 districts can participate autonomously by 1,000.
The main content of the Daegu One Network is to create an environment where citizens can enjoy Wi-Fi for free in various places, and citizen participation is essential. Participating malls will be provided with data for analyzing floating population patterns, which can be used for marketing. The contents of the analysis of the floating population pattern are used as marketing data for each district by using the inflow pattern by time (daily, weekly, monthly, and seasonal). If long-term data is collected, it is possible to discover more sophisticated services.
Meanwhile, to secure financial resources, the Ministry of Land, Infrastructure, and Transport innovation growth engine project (total project cost of 2022 billion won) by 614 will secure transportation, safety and urban administration platforms and data hubs, and build intelligent transportation systems and communication networks by 2023. In addition, 136 billion won will be invested in public funds for this year, and 215 billion won will be raised through public offerings of the Ministry of Land, Infrastructure, and Transport this year.
Data convergence analysis starting from Daegu data hub
The smart business center to be built in Suseong Alpha City in the second half of the year will establish a data hub, collect scattered data, and perform convergence analysis to enable city policy decision-making, provide optimal civic services and create corporate business.
Currently, city data in many cities is only collected, stored, and managed in an integrated manner, so the actual utilization rate is not high. However, the data hub established in Daegu city enables a business model through convergence analysis between data.
For example, it is possible to support decision-making on bus route optimization through convergence analysis, beyond the integrated collection, storage, and management of existing traffic data, floating population, and map data related to the activation of public transportation.
Daegu Smart City certified at home and abroad
Daegu City has provided an opportunity to attract national projects through the creation of Alpha City, and has been designated as a demonstration city for research and development of smart city innovation growth engines by the Ministry of Land, Infrastructure, and Transport (2018) and won the Smart City Asia Pacific Award for two consecutive years (2). ~2018), smart city pilot certification (2019), smart city international standard certification (2019. ISO2020), and Korea's first G37106 global smart city alliance membership (20), making it a representative smart city city in Korea.
This year, in order to solidify the global position of the Daegu Smart City, we are the first in Korea to challenge the 37120 Smart City Asia-Pacific Awards and enter the Global 2021 Smart City Awards, along with the ITU Smart City Standard and Smart City International Standard Certification (ISO 100) under the UN agency. It is going to be promoted.
Daegu Mayor Kwon Young-jin said, “Daegu itself will become a platform of innovation, and in the near future, we will provide smart city services that many citizens can feel and create a smart and livable city where businesses can grow.”
