Determining pickup and destination locations for autonomous vehicles
Aspects of the disclosure provide systems and methods for providing suggested locations for pick up and destination locations. Pick up locations may include locations where an autonomous vehicle can pick up a passenger, while destination locations may include locations where the vehicle can wait for an additional passenger, stop and wait for a passenger to perform some task and return to the vehicle, or for the vehicle to drop off a passenger. As such, a request for a vehicle may be received from a client computing device. The request may identify a first location. A set of one or more suggested locations may be selected by comparing the predetermined locations to the first location. The set may be provided to the client computing device.
1. A method comprising:
receiving, by one or more processors, a request from a client computing device, the request identifying a first location;
identifying, by the one or more processors, a first predetermined location of a plurality of predetermined locations that is a first distance from the first location, wherein the plurality of predetermined locations are locations where a vehicle is able to pick up or drop off passengers;
identifying, by the one or more processors, a second predetermined location of the plurality of predetermined locations that is a second distance from the first location, the second distance being greater than the first distance; and
scoring, by the one or more processors, by assigning a value to each of the first predetermined location and the second predetermined location;
selecting, by the one or more processors, the second predetermined location as a suggested location based on the value for the first predetermined location and the value for the second predetermined location; and
providing, by the one or more processors, the suggested location to the client computing device.
2. The method of claim 1 , wherein the scoring is based on a plurality of factors related to logistical constraints a person encounters in reaching the first predetermined location from the first location.
3. The method of claim 2 , further comprising determining at least one of the plurality of factors based on a distance from the first location to the first predetermined location or the second predetermined location.
4. The method of claim 2 , further comprising determining at least one of the plurality of factors based on walking conditions from the first location to the first predetermined location or the second predetermined location.
5. The method of claim 4 , wherein the walking conditions include whether there are hills.
6. The method of claim 4 , wherein the walking conditions include whether there are sidewalks.
7. The method of claim 4 , wherein the walking conditions include whether a road is crossed.
8. The method of claim 1 , wherein the scoring is further based on a plurality of factors related to logistical constraints the vehicle encounters in reaching and stopping at the first predetermined location or the second predetermined location from the first location.
9. The method of claim 8 , further comprising determining at least one of the plurality of factors based on a current location of the vehicle.
10. The method of claim 8 , further comprising determining at least one of the plurality of factors based on whether the vehicle would have to first pass the first predetermined location or the second predetermined location and turn around.
11. The method of claim 8 , further comprising determining at least one of the plurality of factors based on whether the vehicle would approach the first predetermined location or the second predetermined location from an opposite side of a road.
12. The method of claim 1 , wherein identifying first predetermined location and identifying the second predetermined location are further based on a predetermined distance from the first location.
13. The method of claim 12 , wherein the predetermined distance is defined as a walking distance for a person.
14. The method of claim 1 , further comprising, prior to identifying the first predetermined location and prior to identifying the second predetermined location, determining that the first location is not one of the plurality of predetermined locations.
