Description

In Korea a road construction project, whether it is a government investment project or a private investment project, has often caused a big budget waste due to overestimation of transport demand. For example, the number of vehicles using the Incheon International Airport Expressway, a private investment project, had not reached 50% of the original transport demand estimation made by the government and thus 440 million USD had been given to the private investor as subsidy during the years 2001-2006.

There could be several reasons for such inaccuracy of transport demand estimation, but the main reasons are: (1) low reliability of basic road transport data used for transport demand estimation and (2) inadequate sharing of the data among agencies/departments producing basic road transport data. The Supreme Board of Audit and Inspection also pointed out the same problems as the above in three audit and inspection reports published in the years 2004, 2006 and 2007.

This study is undertaken based on a realization that the two major basic road transport database, ‘The National Transport Database’ and ‘The Household Travel Database in Seoul Metropolitan Area’, have the above-mentioned problems at present, but will be used to the establishment of a road construction plan and thus the ways to improve the problems need to be found. Hence, looking into the problems of basic road transport database projects focusing on the database used for transport demand estimation, proposals for enhancing their reliability and data sharing will be suggested

This study consists of three parts. In the first part, the problems of the road transport database projects are looked into, using the government offices inspection reports of the National Congress, the audit and inspection reports of the Supreme Board of Audit and Inspection, the reports of transport research institutes, and the academic papers. In the second part, the problems looked into are screened and revised through the interview with the relevant officials of authorities such as the Ministry of Land, Transport and Maritime Affairs, Seoul Metropolitan Government, Kyunggi Provincial Government, Metropolitan Transport Authority, etc. In the third part, the improvement proposals for the problems are made and then revised.

Abstract

Roads are an important social infrastructure to facilitate the economic development of a nation by transporting people and goods fast and safely. However, it costs a huge amount of money to construct roads.

In Korea a road construction project, whether it is a government investment project or a private investment project, has often caused a big budget waste due to overestimation of transport demand. For example, the number of vehicles using the Incheon International Airport Expressway, a private investment project, had not reached 50% of the original transport demand estimation made by the government and thus 440 million USD had been given to the private investor as subsidy during the years 2001-2006.

There could be several reasons for such inaccuracy of transport demand estimation, but the main reasons are: (1) low reliability of basic road transport data used for transport demand estimation and (2) inadequate sharing of the data among agencies/departments producing basic road transport data. The Supreme Board of Audit and Inspection also pointed out the same problems as the above in three audit and inspection reports published in the years 2004, 2006 and 2007.

This study is undertaken based on a realization that the two major basic road transport database, ‘The National Transport Database’ and ‘The Household Travel Database in Seoul Metropolitan Area’, have the above-mentioned problems at present, but will be used to the establishment of a road construction plan and thus the ways to improve the problems need to be found. Hence, looking into the problems of basic road transport database projects focusing on the database used for transport demand estimation, proposals for enhancing their reliability and data sharing will be suggested

This study consists of three parts. In the first part, the problems of the road transport database projects are looked into, using the government offices inspection reports of the National Congress, the audit and inspection reports of the Supreme Board of Audit and Inspection, the reports of transport research institutes, and the academic papers. In the second part, the problems looked into are screened and revised through the interview with the relevant officials of authorities such as the Ministry of Land, Transport and Maritime Affairs, Seoul Metropolitan Government, Kyunggi Provincial Government, Metropolitan Transport Authority, etc. In the third part, the improvement proposals for the problems are made and then revised.

This study takes the policy-oriented approach in finding problems rather than the scholastic approach. Accordingly, the improvement proposals for the problems are derived from policy-oriented viewpoint. Therefore, it will be necessary to do scholastic analysis on the practicality and effect of the proposals.
