A computer-based system for road selection

摘要

This paper presents the development of a knowledge-based system for effectively evaluating alternative routes at different traveling times in a medium-size city. A decision analysis technique, the analytical hierarchy process, was incorporated via a preference scale into the reasoning mechanism of the system to evaluate up to 54 possible road segments based on nine major transportation factors. The resulting platform provides travelers with a quantitative measure to compare and contrast alternative routes connecting departing and destination points within the city limits. The developed prototype system, which was successfully validated by independent experts in the field, can be regarded as a new tool in engineering orientation for route finding in transportation systems.
