causing, by the central computing device, the autonomous vehicle to follow the one or more zone rules while operating in the zone, the one or more zone rules limiting behavior by the autonomous vehicle based on one or more conditions that are known or sensed by the autonomous vehicle; and causing, by the central computing device, the autonomous vehicle to be released from the zone rules and to exit the controlled mode when the autonomous vehicle leaves the zone. ### Claim 2 (depends on 1) The method of claim 1, wherein causing the autonomous vehicle to enter the controlled mode of operation comprises causing a control message to be transmitted to the autonomous vehicle that causes the autonomous vehicle to enter the controlled mode. ### Claim 3 (depends on 1) The method of claim 1, wherein causing the autonomous vehicle to follow the zone rules while operating in the zone comprises causing a control message to be transmitted to the autonomous vehicle that contains the zone rules, wherein the autonomous vehicle autonomously follows the zone rules. ### Claim 4 (depends on 1) The method of claim 1, wherein a stream of control messages are transmitted to the autonomous vehicle to be stored on the autonomous vehicle for operation of the autonomous vehicle in the zone. ### Claim 5 (depends on 1) The method of claim 1, wherein the stream of control messages is based at least in part on information transmitted to the zone authority by autonomous vehicles in the zone. ### Claim 6 (depends on 1) The method of claim 1, wherein the zone is an area in which a zone authority controls operation of autonomous vehicles to enforce compliance with the zone rules. ### Claim 7 (depends on 1) The method of claim 1, wherein the zone is a parking facility, tunnel, road, or security area. ### Claim 8 (depends on 1) The method of claim 1, wherein the zone is entered through a physical gate or a communications-based electronic point of control transfer. ### Claim 9 (depends on 1) The method of claim 1, wherein one or more of the zone rules designate speed, vehicle spacing, or lane selection. ### Claim 10 (depends on 1) The method of claim 1, wherein the behavior designated by one or more of the zone rules is further based on conditions within the zone determined by the zone authority. ### Claim 11 (depends on 1) The method of claim 1, wherein one or more of the zone rules require vehicles under control of the zone authority to respond to information communicated to them by the zone authority. ### Claim 12 (depends on 1) The method of claim 1, wherein: the autonomous vehicle comprises a display screen visible to a human driver in the autonomous vehicle; and instructions from the zone authority are displayed on the display screen to prompt the human driver in the autonomous vehicle to follow one or more of the zone rules while operating the autonomous vehicle in the zone. ### Claim 13 (depends on 1) The method of claim 1, wherein one or more of the zone rules coordinate simultaneous operation of a plurality of vehicles in the zone. ### Claim 14 (depends on 1) The method of claim 1, wherein one or more of the zone rules control one or more of: locations of vehicles in the zone; paths of vehicles in the zone; speeds of vehicles in the zone; or use of markers in the zone by vehicles. ### Claim 15 (depends on 1) The method of claim 1, wherein one or more of the zone rules are configured to direct the autonomous vehicle to a checkpoint for clearance. ### Claim 16 (depends on 1) The method of claim 1, wherein one or more of the zone rules require the autonomous vehicle to report periodically to the zone authority the autonomous vehicle's speed or location or conditions sensed by the autonomous vehicle. ### Claim 17 (depends on 1) The method of claim 1, wherein the zone comprises markers that provide information that can be detected by sensors on vehicles in the zone and used to control the vehicles. ### Claim 18 (depends on 17) The method of claim 17, where one or more of the markers have fixed content or content that can be changed in response to conditions in the zone. ### Claim 19 (depends on 1) The method of claim 1, wherein one or more of the zone rules for operation of the autonomous vehicle in the zone further take into account one or more of: one or more capabilities of the autonomous vehicle; reliability of control of the autonomous vehicle; accuracy of control of the autonomous vehicle; a configuration of an area of the zone in which the autonomous vehicle is operating; one or more conditions of the zone determined by one or more other vehicles in the zone; or one or more conditions of the zone determined using zone sensors in the zone. ### Claim 20 (depends on 19) The method of claim 19, wherein one or more capabilities of the autonomous vehicle comprise: traction; turning ability; speed capabilities of the autonomous vehicle; autonomous-operation capabilities of the autonomous vehicle; abilities of the autonomous vehicle to sense and coordinate with other autonomous vehicles; abilities of the autonomous vehicle to communicate with the zone authority; or reliability of the autonomous vehicle. ### Claim 21 (depends on 1) The method of claim 1, wherein: the zone comprises a security area; and one or more of the zone rules are configured to override autonomous or human-driver control of the autonomous vehicle to prevent the autonomous vehicle from entering the security area. ### Claim 22 (depends on 21) The method of claim 21, wherein the security area varies by time, vehicle, or vehicle mission. ### Claim 23 (depends on 1) The method of claim 1, wherein one or more of the zone rules take into account a mission of the autonomous vehicle. ### Claim 24 (depends on 23) The method of claim 23, wherein: the mission of the autonomous vehicle is to provide a service within the zone; and one or more of the zone rules take into account the mission of the autonomous vehicle by directing the autonomous vehicle to a location in the zone where the service is to be provided. ### Claim 25 One or more computer-readable non-transitory storage media embodying software that is operable when executed to: cause, by a central computing device associated with a zone authority, an autonomous vehicle in a zone controlled by the zone authority to enter a controlled mode of operation according to which the autonomous vehicle follows one or more zone rules stored on the autonomous vehicle for operation of the autonomous vehicle in the zone; cause, by the central computing device, the autonomous vehicle to follow the one or more zone rules while operating in the zone, the one or more zone rules limiting behavior by the autonomous vehicle based on one or more conditions that are known or sensed by the autonomous vehicle; and cause, by the central computing device, the autonomous vehicle to be released from the zone rules and to exit the controlled mode when the autonomous vehicle leaves the zone. ### Claim 26 A system comprising: one or more processors; and one or more computer-readable non-transitory storage media coupled to one or more of the processors and comprising instructions operable when executed by one or more of the processors to cause the system to: cause, by a central computing device associated with a zone authority, an autonomous vehicle in a zone controlled by the zone authority to enter a controlled mode of operation according to which the autonomous vehicle follows one or more zone rules stored on the autonomous vehicle for operation of the autonomous vehicle in the zone; cause, by the central computing device, the autonomous vehicle to follow the one or more zone rules while operating in the zone, the one or more zone rules limiting behavior by the autonomous vehicle based on one or more conditions that are known or sensed by the autonomous vehicle; and cause, by the central computing device, the autonomous vehicle to be released from the zone rules and to exit the controlled mode when the autonomous vehicle leaves the zone.
