Audible pedestrian warning system using embedded system

Abstract

Despite their low emissions, hybrid electric cars have caused concerns for the safety of other road users (pedestrians, cyclists, etc.). At low speeds (below 30 km/h), electric and hybrid cars are almost quiet, which poses a risk to pedestrians. This is particularly true for those who are more susceptible to harm, such as the visually handicapped. The primary goal of this project is to create a working prototype of a vehicle (robot) equipped with a pedestrian-detecting automated signaling system and speakers aimed towards the pedestrian. This enhances the vehicle's capacity for responding to its surroundings. The alert tone must also be fine-tuned so that it is audible but not obnoxious.
