Abstract:Vehicle tracking systems were installed on all DIRECT (Driver Information Radio using Experimental Communication Technologies) vehicles to help investigate the
relationships between the drivers’ actual travel experiences and their opinions about the
systems they used. The purpose of this report is to look more carefully at driver behavior
as recorded by the tracking system and to see if this provides any further insight on the
effectiveness of the DIRECT systems. The report first describes the tracking system and
the traffic messages delivered to the drivers, then it goes on to analyze which drivers
responded to the messages by diverting as shown by the tracking system. The last section
addresses how the messages and diversions may have affected the drivers’ reported level of
satisfaction with the system they used.
