Acceptance and Effectiveness of Collision Avoidance System in Public Transportation

Abstract

This study investigated the acceptance and effectiveness of a lane departure warning and forward collision warning in public transportation. Five professional drivers from the Older Adult Transportation Service (OATS) participated in this study. During the experiment, the total number of alarms for each day was collected from the testing vehicles, and survey responses were also gathered from the drivers. Questionnaires were designed to determine whether the collision avoidance system performed as expected and any potential crashes avoided due to the use of the devices. Our results indicated that 75% of drivers showed significant differences in driving behavior after they used the collision avoidance system. 60% of drivers reported positive feedback for the lane departure warning and 40% of drivers felt confident in the forward collision warning.
