The systems and methods provide detection of vehicles and persons in (or predicted to enter) an area of the intersection and provide a signal to the UAV so that the UAV can avoid flying over vehicles and persons. ## Claims ### Claim 1 A method, comprising: determining that an area of a route of a UAV is clear or not clear; and providing, based on the area being determined not to be clear, a signal that is configured to be received by an unmanned aerial vehicle (UAV), wherein the signal is configured to be used to change a speed profile or flight path of the UAV. ### Claim 2 (depends on 1) The method of claim 1, wherein determining that the area is clear or not clear includes determining that at least one of a vehicle and a mobile device is in communication with a control system at the area of the route. ### Claim 3 (depends on 1) The method of claim 1, wherein determining that the area is clear or not clear includes determining that at least one of a person and a vehicle is detected in a measurement by a sensor, wherein the sensor is in communication with a control system. ### Claim 4 (depends on 1) The method of claim 1, wherein determining that the area is clear or not clear includes determining that a location of at least one of a vehicle and a mobile phone is in the area. ### Claim 5 (depends on 4) The method of claim 4, wherein the location is a GPS location and the area is defined by a geo-fence border. ### Claim 6 (depends on 1) The method of claim 1, wherein determining that the area is clear or not clear includes determining at least one time at which at least one of a vehicle and a mobile device is predicted to be in the area. ### Claim 7 (depends on 6) The method of claim 6, further comprising: determining an arrival time at which the UAV is predicted to reach the area along the route; and comparing the at least one time at which at least one of a vehicle and a mobile device is predicted to reach the area to the arrival time. ### Claim 8 (depends on 7) The method of claim 7, further comprising determining a new arrival time based on the arrival time being a time at which at least one of the vehicle and the mobile device is predicted to be in the area. ### Claim 9 (depends on 8) The method of claim 8, further comprising providing the new arrival time to a control system. ### Claim 10 (depends on 9) The method of claim 9, further comprising controlling at least one traffic signal at the intersection to display a stop symbol at least during the new arrival time. ### Claim 11 (depends on 9) The method of claim 9, further comprising sending a message or instruction to at least one of a vehicle and a mobile device to stop outside the area at least during the new arrival time. ### Claim 12 A system, comprising: a road-side unit at an intersection of a route of an unmanned aerial vehicle (UAV), comprising: a processor; a memory, comprising instructions that, when executed by the processor, causes the processor to: determine if an area at an intersection of a route of a UAV is clear; and provide, based on the determination, a signal that is configured to be received by an unmanned aerial vehicle (UAV), wherein the signal is configured to be used to change a speed profile or flight patch of the UAV if the area is determined not to be clear. ### Claim 13 (depends on 12) The system of claim 12, wherein the road-side unit is configured to connect to at least one of a vehicle and a mobile phone. ### Claim 14 (depends on 13) The system of claim 13, wherein determining if the area is clear includes determining if at least one of a vehicle and a mobile device is connected to the road-side unit. ### Claim 15 (depends on 12) The system of claim 12, further comprising at least one sensor for detecting a presence of at least one of a person and a vehicle in the area. ### Claim 16 (depends on 12) The system of claim 12, wherein determining if the area is clear includes determining at least one time at which at least one of a vehicle and a mobile device is predicted to be in the area. ### Claim 17 (depends on 12) The system of claim 12, further comprising: determining an arrival time at which the UAV is predicted to reach the area along the route; and comparing the at least one time at which at least one of a vehicle and a mobile device is predicted to reach the area to the arrival time. ### Claim 18 (depends on 17) The system of claim 17, the memory comprising instructions that, when executed by the processor, causes the processor to control the at least one traffic signal at least during a time at which the UAV is predicted to move through the area along the route. ### Claim 19 (depends on 18) The system of claim 18, wherein the at least one traffic signal is controlled to display a stop symbol. ### Claim 20 (depends on 12) The system of claim 12, the memory comprising instructions that, when executed by the processor, causes the processor to send a message or instruction to at least one of a vehicle and a mobile device to stop outside the area at least during a time that the UAV is predicted to move through the area along the route.
