2003 Journal of transportation engineering  
A case-based reasoning ͑CBR͒ model is presented for freeway work zone traffic management. The model considers work zone layout, traffic demand, work characteristics, traffic control measures, and mobility impacts. A four-set case base schema or domain theory is developed to represent the cases based on the aforementioned characteristics of the problem. It includes a general information set, a problem description set, a solution ͑or control͒ description set, and an effects set. To improve the

The model is implemented into an intelligent decision-support tool to assist traffic agencies in the development of work zone traffic control plans and to better design and manage work zones for increased mobility and safety. Three examples are presented to show the practical utility of the CBR system for work zone traffic management.
