Dynamic Aircraft Routing
A request for transport services that identifies a rider, an origin, and a destination is received from a client device. Eligibility of the request to be serviced by a vertical take-off and landing (VTOL) aircraft is determined based on the origin and the destination. A transportation system determines a first and a second hub for a leg of the transport request serviced by the VTOL aircraft and calculates a set of candidate routes from the first hub to the second hub. A provisioned route is selected from among the set of candidate routes based on network and environmental parameters and objectives including pre-determined acceptable noise levels, weather, and the presence and planned routes of other VTOL aircrafts along each of the candidate routes.
1 . A method for dynamically routing a VTOL aircraft in a transportation system, the method comprising:
receiving, at the transportation system, a request to route the VTOL aircraft from a first location to a second location, the request generated in response to receiving one or more requests for transport services from client devices associated with users of the transportation system;
calculating a set of candidate routes from the first location to the second location;
calculating a route cost for each candidate route in the set of candidate routes, wherein the route cost is a function of one or more network or environmental factors;
responsive to at least one candidate route of the set of candidate routes having a route cost at or below an acceptable route cost threshold, selecting a candidate route as a provisioned route for the transport services based in part on the route cost; and
sending data related to the provisioned route to the VTOL aircraft.
2 . The method of claim 1 , further comprising accessing map data of a geographic region including the first location and the second location and wherein the route costs are based on the map data.
3 . The method of claim 1 , wherein the request for transport services includes a request for transportation from an origin location to a destination location, the transport services including:
a first leg from the origin location to the first location;
a second leg from the first location to the second location, the second leg being serviced by a VTOL aircraft; and
a third leg from the second location to the destination location.
4 . The method of claim 1 , wherein each candidate route in the set of candidate routes optimizes for an objective determined based on one or more of the network or environmental parameters.
5 . The method of claim 1 , wherein the network factors include a number of VTOL aircraft that will be at the first location within a specified time period.
6 . The method of claim 1 , wherein the network parameters include locations of one or more transportation hubs between the first location and the second location.
7 . The method of claim 1 , wherein the environmental parameters include pre-determined acceptable noise levels between the first location and the second location.
8 . The method of claim 1 , wherein the environmental parameters include current and predicted weather between the first location and the second location.
9 . The method of claim 1 , further comprising:
determining that the route costs for each of the candidate routes exceeds an acceptable route cost threshold; and
periodically recalculating the route costs for each of the candidate routes until at least one candidate route has a route cost at or below the acceptable route cost threshold.
10 . The method of claim 1 , wherein the route cost in based in part on vehicle noise profile data for the VTOL aircraft.
11 . A method for dynamically routing a VTOL aircraft in a transportation, system, the method comprising:
receiving, at the transportation system, a request to route the VTOL aircraft from a first location to a second location, the request generated in response to receiving one or more requests for transport services from client devices associated with users of the transportation system;
calculating a set of candidate routes from the first location to the second location;
selecting, from the set of candidate routes, a provisioned route for the transport services based on a noise profile of the candidate route; and
sending data related to the provisioned route to the VTOL aircraft.
12 . The method of claim 11 , wherein selecting the provisioned route comprises:
calculating a cost score for each candidate route in the set of candidate routes, wherein the cost score is based on one or more network or environmental factors;
selecting a first candidate route with a lowest cost score;
determining whether a noise profile for the first candidate route remains at or below an acceptable noise profile threshold for the first candidate route; and
responsive to determining that the noise profile remains at or below the acceptable noise profile threshold, selecting the first candidate route as the provisioned route.
13 . The method of claim 11 , wherein selecting the provisioned route comprises:
calculating a cost score for each candidate route in the set of candidate routes, wherein the cost score is based on one or more network or environmental factors;
selecting a first candidate route with a lowest cost score;
responsive to determining that a noise profile of the first candidate route exceeds an acceptable noise profile threshold at a point on the first candidate route, selecting a second candidate route with a next lowest cost score; and
responsive to determining that a noise profile of the second candidate route remains at or below the acceptable noise profile threshold, selecting the second candidate route as the provisioned route.
14 . The method of claim 11 , wherein the request for transport services includes a request for transportation from an origin location to a destination location, the transport services including:
a first leg from the origin location to the first location;
a second leg from the first location to the second location, the second leg being serviced by a VTOL aircraft; and
a third leg from the second location to the destination location.
15 . The method of claim 11 , wherein the network parameters include a number of VTOL aircrafts that will be at the first location within a specified time period.
16 . The method of claim 11 , wherein the environmental parameters include current and predicted weather between the first location and the second location.
17 . The method of claim 11 , wherein the noise profile is based on noise profile data of the VTOL aircraft and other predicted noise sources along the provisioned route.
18 . The method of claim 17 , wherein the noise profile threshold is based on pre-determined acceptable noise levels in geographic areas within a threshold distance of the candidate route.
19 . The method of claim 11 , further comprising:
determining that the noise profile for each of the candidate routes exceeds an acceptable noise threshold; and
periodically recalculating the noise profile for each of the candidate routes until at least one candidate route has a noise profile at or below the acceptable noise threshold.
20 . The method of claim 11 , further comprising accessing map data of a geographic region including the first location and the second location and wherein the cost score is based on the map data.
