Abstract: The computerized parking facility management system manages parking operations. The contour of each vehicle that enters the parking facility is captured and quantified as part of its identification. The comparison with subsequent contour measurements at designated locations allows the parking location of the vehicle to be determined. An alternate embodiment implements the Global Positioning System to determine parking location. Variable message displays provide ongoing information to motorists of available parking spaces. The system identifies the specific vehicle parked in any parking space. The system provides computer searching to locate vehicles within the parking facility. A vehicle theft deterrence component automatically notifies the vehicle owner, the police, parking facility operators and other appropriate persons. This invention also integrates with parking revenue operations.

Abstract: The Collision Avoidance System prevents collisions between vehicles and vehicular collisions with pedestrians, trains, and stationary objects by monitoring, controlling, documenting, and reporting 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. The system also monitors pedestrians, school bus loading/unloading, traffic density, trains, environmental conditions that may affect driving, and traffic control systems to determine the action to take for collision prevention.
