Collision avoidance system

TLDR: The Collision Avoidance System as discussed by the authors prevents vehicular collisions between vehicles and with pedestrians, trains, and stationary objects by monitoring (50), controlling (40), documenting, and reporting (60) the speed and position of vehicles.

Abstract: The Collision Avoidance System prevents vehicular collisions between vehicles and with pedestrians, trains, and stationary objects by monitoring (50), controlling (40), documenting, and reporting (60) the speed and position of vehicles. The system guards against speeding violations, moving violations, and particular safety hazards by invoking a reduction of vehicle speed or by restricting vehicle movement to control its position. This is primarily accomplished with the activation of a controllable road perturbation (20). The system also monitors pedestrians, school bus loading/unloading, traffic density, trains, road moisture, and traffic control systems to determine the action to take for collision prevention. The capability to monitor various entities that may be involved in a collision or entities that indicate a possible collision is forthcoming allows the system to monitor an entire traffic environment and thus anticipate possible collisions. The system integrates and synchronizes with existing traffic control devices and systems to ensure that it reinforces the traffic laws and safety intent of the environment in which it is installed. A computer (10) is used to determine if the vehicles are adhering to the traffic laws or other safety concerns. Visual displays (70) may accompany the system output to inform the motorist what must be done to prevent a collision.
