Abstract

This report contains the results of the third survey (out of four surveys) that was conducted six months after the IVR system was operational. Drivers who had the IVR in the audible (visual) mode for the first three months would have switched to the visual (audible) mode for the next three months. The audible and visual groups gave similar average effectiveness ratings to all of the warning devices except the flashing lights, clanging bell, and IVR. The audible group rated these three devices higher than the visual group. The IVR average effectiveness rating from the audible group was 3.8 using a 5.0 scale, significantly higher than 2.7 from the visual group. The visual warning message from the visual IVR was not as effective in attracting attention of the drivers as the beeping sound from the audible IVR. This is reflected in its effectiveness rating. The effectiveness rating for the audible mode of IVR was significantly higher than that of the advance warning and the crossbuck signs, similar to that of the train horn, and lower than that of the flashing lights, the crossing gate, and the clanging bell. The effectiveness rating for the visual IVR was significantly lower than that of all other warning devices, except the advance warning sign. The effectiveness rating of the visual IVR was similar to that of the advance warning sign. A significantly higher proportion of the audible group (72%) compared to the visual group (47%) trusted the IVR to give an accurate warning of a train approaching/occupying the equipped crossings.
