Existing approaches to developing real-time routing strategies, however, have limitations. This study explored the potential for using case-based reasoning (CBR), an emerging artificial intelligence paradigm, to overcome such limitations. CBR solves new problems by reusing solutions of similar past problems. To illustrate the feasibility of the approach, the research team developed and evaluated a prototype CBR routing system for the interstate network in Hampton Roads, Virginia. They generated cases for building the system's case-base using a heuristic dynamic traffic assignment (DTA) model designed for the region. Using a second set of cases, the research team evaluated the performance of the prototype system by comparing its solutions with those of the DTA model. The research team found that CBR has the potential to overcome many of the limitations to existing approaches to real-time routing and a CBR routing system is capable of producing high-quality solutions with reasonable a case-base size. In addition, the research team found that real-time traffic flow routing will likely lead to significant user cost savings.
