AI Detection
Deep-learning video analyticsDetects vehicles, pedestrians and two-wheelers alike, and turns the road into numbers — volume, speed and occupancy, recalculated second by second.
INTELLIGENT TRANSPORT SYSTEMS
Intelligent Transport System
An Intelligent Transport System (ITS) applies electronics, control and communication technology to roads and vehicles, so that traffic operations are managed scientifically and automatically — making the network both more efficient and safer.
There is a limit to how many lanes you can add. ITS is about using the road you already have more intelligently — reading how each vehicle moves, retiming signals, warning of a queue before it forms, and noticing an incident within seconds.
SangLim builds the whole chain: AI deep-learning detection that collects live traffic data, the processing that turns it into usable information, and the roadside displays, bus terminals and control room dashboards that deliver it.
Unified Display
Built in-house, end to endVMS roadside signs, BIT bus terminals and charging-station displays are all designed and manufactured by SangLim, so size and format follow the site rather than the catalogue.
Center Integration
One screen for the whole corridorCollected information is fed into control-room dashboards and agency systems, so an incident picked up in the field flows straight into the response procedure.
Field Reliability
Designed for the outdoorsHeat, cold, vibration and lightning are assumed from the start — and inspection and maintenance after installation are handled by the manufacturer directly.
HOW IT WORKS
From road data to something a driver can read
A sensor reading passes through three stages before it becomes a sentence on a sign.
Collect
Detectors and cameras on the road read every vehicle’s presence, speed, plate and image, second by second.
Process
AI deep-learning models turn the raw feed into flow states, incident alerts and predicted travel times.
Deliver
The processed information goes straight back to the road and to the traveller’s screen.
SERVICE DOMAINS
Seven service domains
Traffic management
Signals, incidents and enforcement run as one system
Public transport
Bus position and arrival times delivered to riders
Electronic payment
Tolls and fares settled without stopping
Data distribution
Collected information shared with agencies and industry
Value-added services
Parking, weather and tourism data linked in
Intelligent vehicle & road
Vehicles and roads cooperating over radio
Freight operations
Safety and efficiency for goods vehicles
C-ITS
Cooperative ITS
Classic ITS sends information down from a control centre. C-ITS lets vehicles, roads and pedestrians exchange it directly — the precondition for automated driving.

NECESSITY
Why it matters
POINT 01
Improved safety at accident-prone locations
POINT 02
Higher accuracy in vehicle recognition
POINT 03
Relief for chronically congested sections
POINT 04
Detection of pedestrians and two-wheelers that sensors miss
SOLUTION
Key solutions
Variable Message Sign (VMS)
Roadside displays that deliver live traffic information to drivers
Intelligent camera
AI video analysis that recognises vehicles and collects volume data
Control room dashboard
Software that monitors the whole network on one screen and drives the response
Field controller
On-site unit that ties detection and display equipment back to the centre
POLICY
Policy direction — ITS Master Plan 2030
Korea’s Ministry of Land, Infrastructure and Transport set out four strategies under the vision of “green, safe and seamless people-centred transport services”.
Infrastructure for new modes of mobility
Laying the road foundation that automated vehicles and UAM will need before they arrive.
Closing the safety blind spots with AI
Video analytics detects pedestrians and two-wheelers that conventional detectors miss.
A base for user-tailored services
Opening the collected traffic data so private services can build on top of it.
Support for exporting Korean ITS
Turning technology proven at home into an export industry.
