摘要：	Vehicle tracking systems were installed on all DIRECT vehicles to help investigatethe relationships between the drivers’ actual travel experiences and their opinions aboutthe systems they used. The purpose of this report is to look more carefully at driverbehavior as recorded by the tracking system and to see if this provides any further insighton the effectiveness of the DIRECT systems. The report first describes the trackingsystem and the traffic messages delivered to the drivers, then it goes on to analyze whichdrivers responded to the messages by diverting as shown by the tracking system. The lastsection addresses how the messages and diversions may have affected the drivers’reported level of satisfaction with the system they used. Main findings reported are:1. The DIRECT drivers rarely diverted from their routine commute. However, onthose occasions when a driver did divert it was likely that they were responding to atraffic message delivered by RDS/SCA, hence the majority of diverted drivers usedRDS/SCA. Furthermore, the tracking data show that about one third of the trackedvehicles diverted around heavy construction. This diversion rate was much higher thanthe rates of diversion for the other systems used. We speculate that the high diversionrate of RDS/SCA resulted from the distinct timeliness and broad coverage of theRDS/SCA message interrupts.2. The most relevant message components include incident location and incidentduration. Queue length is another important message element.3. Drivers that encountered incidents while using RDS/SCA reported higher levels ofsatisfaction with the system than drivers that encountered incidents while using the othersystems Table 4 shows that RDS/SCA has the highest satisfaction rating followed byLPHAR, AHAR, and Cellular.4. A measure of effectiveness based on information content, system reliability, andsound quality showed that RDS/SCA was most effective and Cellular was the leasteffective system tested in DIRECT.The tracking system provided information that was crucial for the evaluation of thetraffic message system and driver behavior. Tracking was one of the most useful toolsimplemented in the DIRECT project.
