Quieter vehicles (hybrid electric, 100% battery electric) on the roadways may affect blind pedestrians– ability to travel safely since they often rely on hearing vehicles to successfully navigate and cross streets. In the current study, a hybrid electric vehicle equipped with an artificially generated alert sound was detected at a significantly farther distance than the hybrid electric vehicle without such a sound and at a similar distance as a comparable internal combustion engine vehicle. The findings of this study may help blind pedestrians understand how adding an artificially generated sound to a hybrid electric vehicle could affect their orientation and mobility tasks.
