BESTool: a blackboard shell and its application to a traffic control problem

An expert systems tool based on blackboard architecture called BESTool (Blackboard Expert System Tool) is described. The software includes a blackboard shell written PROLOG and an application program for a small-scale street traffic control problem. The structure of the shell and its control strategy are described. The applicability of this shell to real-time control is demonstrated through the design and simulation of a single-junction street traffic control problem.<<ETX>>
