These systems automatically operate and manage the traffic system to improve efficiency and
ensure safety.
Starting in 2009, Daegu has implemented the ATMS in three phases to provide drivers with real-
time traffic information (e.g., travel time, speed). ATMS solves and traffic problems such as traffic
congestion and longer emergency response times. It also helps to establish efficient traffic policies
by analysing accumulated traffic information.

Traffic information is collected in real time from roadside base stations, vehicle detector systems
(VDS) and closed-circuit television (CCTV) installed on major arterial roads. This information can
be checked in vehicle terminals, roadside electronic signs, websites, and on mobile devices.
In addition, the Urban Traffic Information System (UTIS) was built between 2013 and 2014 to
manage traffic flow efficiently by distributing traffic in congested areas by providing optimal route
information to destinations reflecting real-time traffic conditions of roads.
The UTIS collects traffic information (travel route, location, speed, etc.) by road section from on
board equipment (OBE) installed in major cities across the country by the National Police Agency,
such that drivers can select a driving route to their destination using real-time information including
CCTV images transmitted to their navigation system.
