Establishment of a ComprehensiveTransportation Information Infrastructure

Building Korea Transport Database

The Korea Transport Database (KTDB)

KTDB is a comprehensive and standardized system that investigates, analyzes, and manages the basic transport statistics necessary to establish transport policies and plans. It includes databases on the operation of transport infrastructure and means (such as roads, railways, airports, harbors, and distribution facilities), origin-destination (O/D) travel, traffic attributes, and transport networks.


  • Gain credibility of basic transport data : Build trust through long-term transport investigations
  • Improve efficiency of transport investments : Use accredited transport analysis data to identify appropriate projects and determine investment priorities
  • Build infrastructure for transport information : Analyze and manage national basic transport data

Background and Purpose

  • Overrun of independent
  • Low credibility
    of transport
  • Lack of databases
    to support
    transport policies
    and plans
Necessity to build and operate national transport database for integrated data management related to transport
Oversee independent transport investigations Legal grounds : National Transport System Efficiency
