Abstract | The negative effects of traffic congestion have been widely acknowledged. They include a decrease in air quality and productivity, and an increase in energy consumption. Unfortunately, adequate responses to control the growth of traffic congestion are limited. The transportation demand management (TDM) has become popular as an option to alleviate traffic congestion which does not require a new major investment. Evaluating TDM alternatives for reducing traffic congestion calls for careful and articulate procedures. When the impacts of the proposed TDM alternatives are evaluated, they should include not only direct ones on the transpo11ation system but also externalities such as the environment. In addition, social aspects such as equity and ease of implementation should be included as well. This di ssertation proposes a multi -criteria decision making approach for evaluating TDM alternatives by considering impacts on transportation, environment and social aspects, which deal with uncertainty in both quantitative and quali tative cri teria. The uncertainty regarding subjective judgments of experts on the social aspects of TOM schemes employ an evidential reasoning (ER) approach. The ER approach is based on the decision and OempsterShafer theories of evidence and can handle unce11ain, imprecise and incomplete data. The first step of the proposed approach is to employ the Analytical Hierarchy Process (AHP) to determine weights of criteria. Forty-two experts from transportation, environment and social science groups are interviewed in this step. In the second step, the achievement of the proposed TDM alternatives in terms of transportation, environment and social aspects are evaluated. The impacts on the transportation are evaluated by using a traditional 4-step based transportation demand modeling software (i .e. TRIPS), while the environmental impacts are estimated by the MOBILE5a-THAI model in terms of nitrogen ox ides (NOx), carbon monoxide (CO) and hydrocarbons (HC). The social impacts are evaluated through subjective judgments of the experts. The social impacts of the proposed TOM alternatives are treated as uncertain and incomplete and are quantified by means of evidential reasoning. In the thi rd step, the ranking of the proposed TDM altern atives is obtained by using the CODASID method based on a complete concordance and discordance analysis. The central business di strict (CBD) area of Bangkok, Thailand with an area of about 22 krn2 has been selected as a study area for the application of the proposed methodology. Fom1een TDM alternatives are evaluated and the ranking of them has been decided. |
