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 continual support past the prototype demonstration through a team familiar with the problem and the system building technique.

This synthesis will be of interest to engineering managers, design engineers, traffic engineers, computer personnel, and others interested in advanced computer applications for highway design and operations. Information is provided on the history of knowledge based expert systems (KBES), current applications of these systems in transportation departments, potential applications, and hardware and software requirements. Additionally, some detailed programming information from two operational expert systems is included. There is growing use of computers in transportation departments, and KBES represent an area in which several highway agencies are gaining experience and obtaining promising results. This report of the Transportation Research Board describes the current state of the practice with respect to KBES, as well as the historical development of expert systems and the more general field of artificial intelligence. Experience with expert systems in transportation in summarized, including discussions of expert systems in operation and in development, based on a review of the literature and a survey of the states and experts in this field.

Engineering, medicine, computer science, mathematics, and business all use applications of expert systems for problem solving that would normally require human skill. These expert systems solve varied problems with a similar procedure - so that knowledge of their use in other specialties will inevitably benefit yours. Expert Systems: Applications for Structural, Transportation, and Environmental Engineering provides a comprehensive, concise treatment of knowledge-based expert systems that introduces you to the flavor, concepts, and capacity of this powerful procedure. Expert Systems covers preliminary design of three-dimensional grids, design systems for low rise industrial buildings, preliminary design of frameworks, bridge design systems, and retaining wall design - especially the methodologies for these applications to structural design. The author presents design standards, typical expert systems for construction engineering and management applications, and the underlying concepts of expert systems, emphasizing bridge analysis, rating, and management. He describes the methodology and applications which aid the transportation and highway engineer in planning, design, and operation and addresses several applications in the fields of environmental and water resources engineering. Automation of the advice-giving of experts is used in design, process planning, manufacturing schedule, quality control, and diagnosis by a range of disciplines. Expert Systems increases your awareness of the versatility of expert systems in these disciplines and offers the theory and algorithms you need to use expert systems in design, maintenance, and construction.
