A STRUCTURE OF PROBLEM-SOLVING METHODS FOR REAL-TIME DECISION-SUPPORTIN TRAFFIC CONTROL

This article describes a knowledge-based application in the domain of road traffic management that we have developed following a knowledge m odelling approach and the notion of problem-solving method. The articl e presents first a domain-independent model for a real-time decision s upport as a structured collection of problem solving methods. Then, it is described how this general model is used to develop an operational version for the domain of traffic management. For this purpose, a par ticular knowledge modelling tool, called Knowledge Structure Manager ( KSM) was applied. Finally, the article shows an application developed for a traffic network of the city of Madrid and it is compared with a second application developed for a different traffic area of the city of Barcelona.
