This paper documents the general procedures and results associated with a before-and-after analysis of Phase 1 of the San Antonio TransGuide System. This analysis focuses on the issues of: (1) safety; (2) incident management; and (3) driver understanding and utilization of the system. The first phase of TransGuide System became operational July 26, 1995 and includes 26 miles of freeway in the downtown San Antonio area.
