Abstract:The drivers who received a combined audible and visual message (combination group) responded that the average effectiveness rating of the IVR was3.6 using a 5.0 scale. This was higher than the 2.5 rating from the drivers who received only a visual message throughout the study (visual-plus group). The combination group gave the IVR a rating that was similar to the clanging bell and the train horn, lower than the ratings for the crossing gate and flashing lights, but higher than the ratings for the advance warning and crossbuck signs. The visual-plus group gave IVR a rating that was similar to the advance warning sign, but was lower than the ratings of the other warning devices. About 61% of the combination group trusted the IVR to give an accurate warning of a train presence compared to 33% for the visual-plus group. For participating drivers who had experience with the audible, visual, and combination modes, the IVR had a high or very high ability to attract the attention of 71.0% using the audible mode, 26.7% using the visual mode, and 77.2% using the combination mode. Approximately 54.9% of the drivers preferred the combination mode, 20.1% of the drivers preferred the audible mode, and 3.7% preferred the visual mode. About 58.5%, of the drivers indicated that none of the warning methods was a significant distraction while driving. However, the IVR distracted 7.3% of the drivers in the combination mode, 4.9% in the visual mode, and 15.2% in the audible mode. Overall, 47.1% of the drivers were in favor of the IDOT installing IVR systems at more railroad crossings, while 31.1% were not, and about 21.8% did not have an opinion or did not answer this question. Given a choice, 44.7% of the drivers said they would continue to use the IVR, 42.2 % said they would not, and 12.7% gave no opinion.
