The document describes a pedestrian preclusion system that uses radar and stereo sensors to detect obstacles and potential collisions. It warns the driver initially and then automatically applies smooth brakes to stop. To address collisions at night, it is equipped with infrared illumination. The document also discusses future possibilities like vehicles communicating their positions and velocities using dedicated short range communication (DSRC) through radar, radio, and cameras to collectively avoid accidents in an example of machine-to-machine communication and coordination. The overall goal is to lay the groundwork for safer transportation through artificial intelligence and analysis of large data.
