Knowledge Based Expert System in Transportation Engineering and Traffic

friendship ground serious System in transport Engineering and handicraft accommodative Signal consider SystemI. AbstractAdvances in computer technologies have been changing transportation field. Based on those, intellectual deportation System has been proposed and being developed for the next generation transportation system. This system requires more utilization of Artificial Intelligence, such as Knowledge Based Expert System, than current one. Although Knowledge Based Expert System has not been robustly studied in the field of transportation, it is suggested to be implemented in Traffic Adaptive Signal Control System as a part of Intelligent Transportation System. Therefore, it is fundamental to overview that what the current position of Knowledge Based Expert System in transportation is. It will help to construct a specialized knowledge on and understand that system in Transportation. Previous applications of Knowledge Based Expert System in transportation field are brie fly reviewed, and potential implementations are discussed by focusing on Traffic Adaptive Signal Control System in this paper.Key words Knowledge Based Expert System, Intelligent Transportation System, Traffic Adaptive Signal Control System.II. IntroductionAdvances in computing have dramatically changed the transportation field in the last decades. These enhance the speed and credit of traffic analysis and acknowledge transportation engineers to study various problems that would not be possibly answered without computer techniques, such as simulations. On the other hand, transportation system have been experient congestion during its peak hours. To solve this, its facilities have been expended in order to increase their capacity by means of adding addit... ...ion Support Architecture For Advanced Traffic solicitude Department of Civil and Environmental Engineering and Institute of Transportation Studies, University of California, Irvine, CA September 1989.6.
