Incorporating Uncertain and Incomplete Subjective Judgments into the Evaluation Procedure of Transportation Demand Management Alternatives

Transportation demand management (TDM) strategies can be the most cost-effective ways to improve transportation system efficiency. This paper proposes a methodology for evaluating TDM alternatives in the context of multi-criteria decision making (MCDM). The proposed approach takes into account not only quantitative criteria (i.e. transportation and environmental impacts) but also qualitative criteria (i.e. social impacts) which are intrinsically uncertain and subjective. The transportation impacts of the TDM alternatives are estimated using the transportation planning software package called TRIPS, while the MOBILE5a computer program is used to estimate environmental impacts in terms of oxides of nitrogen, carbon monoxide and hydrocarbons. The social impacts of the TDM alternatives are estimated by interviewing relevant experts. Consequently, the uncertain subjective judgments were quantified by the evidential reasoning approach based on decision theory and Dempster-Shafer theory of evidence. In order to measure the weights of criteria, analytical hierarchy process is adopted. As a last step, the CODASID method based on a complete concordance and discordance analysis is used to rank alternative TDM schemes. Fourteen TDM alternatives, chosen for the central business area in Bangkok, are ranked to demonstrate the proposed approach. Findings showed that social impacts had a significant influence on the ranking of the TDM alternatives.
