A camera vision-based collision avoidance system (CAS) installed on buses in Miami-Dade increased transit operator response to rear-end and pedestrian conflict scenarios, but had mixed results with respect to user acceptance.
To measure driver acceptance, a survey of the operators was conducted to capture perceptions of ease of use, usefulness, warning effectiveness in each scenario, and system accuracy.
Data Limitations…

A camera vision-based collision avoidance system (CAS) installed on buses in Miami-Dade had a benefit-cost ratio ranging from 1.24 to 1.86 on routes with high historical crash rates.
Data Limitations
During the study, there were route changes that affected the ability to assess early data using the original experimental design. As a result, most of the analyses used the period…
