Fatal bus and pedestrian collisions have increased dramatically recently due to the distractions from various portable electronic devices. The goal of this project is to investigate various sensors for collision detection and propose efficient warning approaches for bus operators and pedestrians. Current solutions use repeating audio warning to alert pedestrians and bus operators. They measure steering column for turning detection, which requires extra devices installed on the vehicle steering system and broadcast message alerts with no consideration of the actual situations. Global positioning system (GPS) signal and onboard IMU (Gyroscope and Accelerometer) will be integrated to analyze the bus motion during turning. These sensors together with the computation component require no change on the basic vehicle structure and present actual motion information for crisis prediction. Various sensor technologies, such as laser detector, sound detector and regular cameras, will be evaluated to provide better detection and distance estimation of pedestrians.
