ITS APPLICATIONS TO SUPPORT THE COLLECTION, COMMUNICATION, AND USE OF REAL-TIME TRAVELER INFORMATION: LESSONS LEARNED FROM THE NATIONAL EVALUATION OF THE SAFETRIP-21 INITIATIVE

摘要

The SafeTrip-21 (Safe and Efficient Travel through Innovation and Partnerships for the 21st Century) initiative was established to test and evaluate integrated, intermodal ITS applications, particularly those that do not entail extensive public sector infrastructure but can achieve immediate benefits and demonstrate the potential for sustainable deployment. These efforts and resulting applications support the U.S. DOT goals to improve safety, reduce congestion, and advance the nation’s transportation system. A total of 8 applications were deployed and tested across two test beds. SAIC was selected to conduct an independent national evaluation of these technologies which concluded in May 2011 and provided lessons learned to the ITS community related to technology use, consumer response, user-perceived benefits, and technical and institutional issues.
