Advisory System Assisting Selection of Strategy on Transport Demand Management (TDM) Using Expert System Shell Method

n many developed cities around the globe, researches have proved that Transport Demand Management (TDM) is an effective measure to alleviate urban congestion of which supplying strategies alone could not solve the problem. TDM comprises wide range strategies and policies that are different in nature which can be divided into several categories according to how they affect travelersʹ behavior. Determining the suitable strategies is a complex process that depends on multiply factors and need the expertise. The right selection of strategies determines the exactness of implementation as well as effectiveness. Therefore, this paper presents the development of an Expert Advisory System for Selection of Implementation Strategies for TDM (E-ASSIST). The process of organizing the available knowledge of TDM strategies, as well as the process leading to the selection of one or more strategy advice, is encoded in the knowledge based expert system shell developed for the purpose by using shell expert system Kappa-PC version 2.4 which was adopted object oriented and high resolution graphical user interface. The advice given from the working system was evaluated and validated by comparing the output of the system against the recommendations made by transportation professionals. The evaluations indicate favorable results for the system. The E-ASSIST system can be used as a decision support system as well as a teaching tool for junior transportation engineers, planners, private developers, and government officials.
