Dr. Kitti Subprasom received a BE degree in Civil Engineering from King Mongkut University of Technology Thonburi, and MS and Ph.D. in Civil Engineering from Utah State University, USA. He is specializing in transportation planning and modeling, transportation network design problem, and uncertainties and risk analysis. Currently, he works at Department of Highways, Bureau of Planning. He is responsible for highway development plan, and carried on several feasibility studies. Last year he was a project manager of Assessment of Highway Transportation Network Vulnerability for Disaster Preparedness Project. The purpose of this project is to develop a decision support system (DSS) tool for assessing vulnerability of highway networks. The case study of Chao Phraya River basin flood provinces in Thailand is adopted to demonstrate how DSS can be applied to the real case.

Assessment of Highway Transportation Network Vulnerability for Disaster Preparedness

Highway transportation network is an essential backbone for supporting passenger transportation, the industrial activities and economic developments of nation. Although it is critical to functioning of a modern society and industry, they are also vulnerable. Highway transportation network is considered as one of the economic lifelines which demand meticulous security consideration, especially in the aftermath of disastrous events such as: man-made attacks and natural disasters. Their impacts significantly degrade the performance of the highway system. Failures on highway networks will consequently halt or delay business continuity, industrial production, essential services, and even the national economy. Thailand has been experiencing a significant increase of various natural disasters especially disasters related to the global climate change effect such as flood. The 2011 mega flood in central area of the country or Chao Phraya River basin, for example, was severely attributed to the failure of highway transportation system as some cannot fully operated or some were even shut down for several days. In that time, disruption to highway can seriously damage the economic productivity as well as making people’s daily lives extremely difficult. The adverse losses caused by that catastrophe were inestimable.

Planning Bureau, Department of Highways (DOH) has realized and anticipated the issues, therefore initiated the project of Assessment of Highway Transportation Network Vulnerability for Disaster Preparedness. The objectives of this project are to 1) assess vulnerability of highway network and identify the critical locations, 2) develop a GIS database for archiving input data and the analysis results, 3) develop a decision support tool for assessing transportation network vulnerability, and 4) conduct a case study based on the disruption scenarios of highway links and develop a highway development plans for mitigating the corresponding impact.
