Financial Savings with Efficient Operation of Government’s Transport Social Overhead Capital (SOC) Investment
- Supporting development of various plans, identification of legitimate projects, evaluation of transport investments, and monitoring mid-term transport SOC
- In terms of traffic management, it is possible to build prediction systems and monitoring support systems with traffic congestion maps
Examples of usage of traffic congestion map
Reduction of Direct Costs with Prevention of Overlapping Transport Investigations and Analyses
- Saving about 140 billion won of the annual investigation budget from the service order budget of the transport division of central department and local government
- Saving about 3.3 billion won of the annual cost by providing KTDB to other organizations
- Preventing budgetary waste and shortening project timelines with improved transport demand forecast ※ Example: Saved about 200 billion won of annual financial support for deficit of Incheon Airport Expressway and Railway Project (in 2007)
Securing Objectivity and Improving Credibility
Developing Guidelines for National Transport Investigations and Sharing Standard Investigation Data
Guidelines for Transport Investigation has been enacted and operated from October 2003 to standardize matters related to standards and methods of transport investigation
Improving Confidence Level of Traffic Forecasting
- Margin of error before KTDB: Approximately 20% - 300%
- Margin of error after KTDB: Approximately within 17%
Comparing margins of error of traffic forecast before and after using KTDB
Comparing Margins of Error Before and After KTDB
- KTDB was used on road projects undertaken before KTDB to reduce erroneous predictions
- For 14 out of 23 national highway projects and 3 out of 10 public road projects, project sizes were reduced and SOC investments were adjusted to match appropriately
Government’s National Transport Statistics Organization with Public Confidence
- Supervised by Statistics Korea
- Ministry of Land, Infrastructure and Transport, and Statistics Korea’s national e-index: Compiling and providing distribution ratio information for taxis and public transportation
- Providing credible statistics to international organizations, including International Transport Forum (ITF), World Bank (WB)

Globalization of KTDB
Exchange with Developed Countries
ITF, WB, US Bureau of Transportation Statistics, etc.: Annually providing quarterly national transport statistics
Exchange with Other Countries: KSP
Sharing Korea’s experiences of building and using KTDB through Knowledge Sharing Program (KSP)
Expansion of Exchanges with Overseas Universities
Creation of MOUs and international seminars
Knowledge Sharing through Promotion
Public Expansion of Microdata
Publically sharing microdata of standard passenger investigations, standard freight investigations, and public transport usage investigations
Shared Analyses with the Public
- O/D, network, and GIS traffic network maps used to predict transport demand every year
- Release additional data required to predict transport demand (VDF, mode choice, etc.)
Frequent Achievement Presentations and Policy Forums to Share Project Progress
