In an emergency, the computer on a vehicle may not be able to find the best avoidance or harm-minimization maneuver in time. This Patent shows how vehicles can get help from a land-based supercomputer, which explores millions of avoidance and harm-minimization scenarios (including pre-tested ones), selects the most effective, and transmits it back to the vehicle in milliseconds.  
Result: VEHICLE HAS THE BENEFIT OF BEST KNOWN SOLUTION.

To coordinate their actions, vehicles in traffic need to localize each other. In this Patent, each vehicle emits a pulse of light and simultaneously transmits a wireless message, thereby identifying themselves to other vehicles. They can then communicate to avoid or minimize harm of an imminent collision.
Result: COOPERATIVE COLLISION AVOIDANCE.

When vehicles in traffic come within range with each other, they emit light pulses encoded by their wireless addresses. Other vehicles can receive the data optically. After exchanging addresses, they can then communicate directly with each other for collision avoidance and harm minimization.
Result: COORDINATION FOR SAFETY AND TRAFFIC FLOW.

Normally, there is no way for a vehicle to know the wireless address of another vehicle in traffic. In this Patent, each vehicle displays a "connectivity matrix", which is a sign or label that indicates the wireless address in a computer-readable pattern. After reading the code, each vehicle can communicate autonomously with the others to avoid or mitigate collisions and smooth the flow of traffic.
Result: VEHICLES COOPERATE FOR TRAFFIC MANAGEMENT AND COLLISION AVOIDANCE.

Disclosed is a method for collision avoidance and harm minimization, using three coordinated computers - a processor in the vehicle, a workstation in a roadside access point, and a remote supercomputer. Exploiting the immense computing power of the supercomputer, they can find the best collision avoidance/harm minimization strategy and implement it immediately.
Result: COLLISION AVOIDED = LIVES SAVED.

Managed collision avoidance and harm minimization requires rapid decision-making. Disclosed are examples wherein a land-based supercomputer and a roadside access point can assist a vehicle in traffic by determining an optimal series of actions to avoid or minimize harm of an imminent collision.
Result: COLLISION AVOIDED = NOBODY HARMED.

An autonomous vehicle can avoid or minimize the harm of a collision, using assistance of a supercomputer trained in traffic mitigation. The vehicle can send an emergency message to a roadside access point, which forwards the data to the supercomputer, which selects the best sequence of actions.
Result: FEWER FATALITIES IN TRAFFIC.

Inter-vehicle signaling is essential for cooperative collision mitigation. Autonomous and semi-autonomous vehicles can identify and localize each other by transmitting simultaneous wireless and infrared signals, thereby enabling coordinated collision avoidance and harm-minimization maneuvers.
Result: THIS SYSTEM WILL SAVE LIVES.
