The validation and evaluation of an expert system for traffic control in highway work zones (TRANZ) is described. The stages in the evaluation process consisted of the following: revisit the experts, selectively distribute copies of TRANZ with documentation and an evaluation form, perform research on identifying related problems that affect the problem domain of TRANZ, and conduct a formal evaluation workshop. It was found that it is very difficult to develop a system that will accurately handle all possible permutations of a problem. The validation process should establish a range of applicability, which can be continually updated as the system 'grows' with experience. All expert systems are seen to require a mechanism for contimual support past the p rototype demonstration through a team familiar with the problem and the system building technique.
