Figure 17: Visualization of the Daegu data hub concept

The purpose of the data hub is to support city operators to:

1. Collect, store and manage city data
2. Provide cross-domain analysis

3. Suggest solutions to urban problems

4. Provide the private sector and inhabitants with open data to solve various urban problems

Daegu has decided to use the data hub as a city operations platform for data-driven smart
sustainable city operations.

In the first phase, all the data from Daegu will be collected, stored and managed in the data hub.
Daegu legacy data will be transmitted directly to the data hub, and various city data streams such
as traffic, safety, and urban facilities will be transmitted from current city service platforms to the
data hub.

Among the many issues that could potentially be solved through data analysis, bus route optimization
and building a city safety infrastructure were selected as the most urgent tasks. A cross-domain
analysis algorithm to solve these issues will be developed and city operators will be provided with
solutions. In addition, an open data portal will be built and operated so that data can be opened
and utilized by private and public institutions. The first phase will be completed in 2021 and is
scheduled to become operational in 2022.
