15 Industry Survey Findings For this synthesis, a survey was conducted of select transit agencies to obtain their perspective and experiences regarding onboard collision avoidance technologies aimed at reducing bus accidents and incidents. The 38-question survey questionnaire (included in Appendix A)

Survey Results 17 of the responses is greater than 100 percent, as shown in Figure 7. Some of the responses that were detailed as "other" included operator stress, schedule pressures, equipment failure, complacency, blind spots in cutaways, and weather conditions.

18 Current Practices in the Use of Onboard Technologies to Avoid Transit Bus Incidents and Accidents asked to identify which safety technologies are utilized, or have been considered, by their agency. Figure 9 shows that onboard security cameras are the most considered technology, with 93 percent of agencies indicating they have at least considered them.

Survey Results 19 more of a clarification as to how rural transit agencies rely upon their state DOT to procure the vehicles they use. The other 19 responses primarily identified the use of passive collision avoidance technologies, such as lane departure warnings, pedestrian detection, audible turning warnings, and driver fatigue detection technologies.

20 Current Practices in the Use of Onboard Technologies to Avoid Transit Bus Incidents and Accidents Transit agencies were asked why they considered the implementation of the collision avoidance technology, and they were specifically asked if the consideration was in response to specific safety events or trends. Responses varied from proactive consideration due to benchmarking with peer agencies and additional funding available to reactive consideration due to increased trends in pedestrian collisions.

Survey Results 21 The majority of respondent agencies (85 percent) reported that they piloted/tested the collision avoidance technology prior to full deployment on their bus system.

24 Current Practices in the Use of Onboard Technologies to Avoid Transit Bus Incidents and Accidents For the agencies that responded that they did procure some type of collision avoidance technology, 46 percent indicated that the transit vehicles were modified at the transit agency by vendor technicians, agency personnel, or both, while 4 percent indicated that the manufacturer prewired the transit bus during final vehicle assembly. As expected, these collision avoidance technologies are typically installed on buses that operate in urban environments, where more transit buses operate and there is higher potential for interaction with other road users.

Survey Results 25 types of technologies that were included in the survey responses included antilock brakes and a rear sensor on a paratransit vehicle that made an audible alert when an object was detected to be close to the vehicle. Once the ATU operator survey respondents identified the type of bus collision avoidance technology exposure, the next question asked respondents to indicate their experience with each of the technologies identified.
