Abstract: A system receives a service request sent from a computing device of a user, which identifies a service to be provided. The system then identifies potential locations based on the service request and historical data. These locations are assessed based on predetermined criteria, including an amount of successful and unsuccessful service requests at each location according to the historical data. After a location is chosen, the user's acceptance is obtained. Upon receiving this acceptance, the system generates and sends navigation instructions from the provider's current position to the selected location to a second computing device associated with the provider.

Abstract: A network system receives a service request sent from a computing device of a user. The service request identifies a service to be provided by a provider and a service request location. In response to receiving the service request, the network system identifies a plurality of candidate locations. The network system selects the location from a plurality of candidate locations according to predetermined criteria including a frequency measurement of each candidate location. The network system replaces the service request location with the selected location. The network system sends the selected location to the computing device. Responsive to receiving an acceptance of the selected location from the computing device, the network system generates navigation instructions for the provider from a current location of the provider to the selected location.

Abstract: A transportation management system analyzes data characterizing trips associated with an access point where a rider is picked up by, or dropped off by, a driver. The transportation management system determines trip metrics for the access point based on the data. The transportation management system identifies an access point defect for the access point using the trip metrics. The transportation management system flags the access point as associated with a missing road segment responsive to identifying the access point defect. The transportation management system performs a resolution action to address the access point defect.

Abstract: A coordination server receives a request from a client device of a rider for transportation from a first location. The coordination server identifies a frequent spot based on the first location. The frequent spot is associated with a particular location and represents a plurality of historic first locations within a threshold distance from the frequent spot. The coordination server identifies a closest road segment with respect to the frequent spot. The closest road segment is a road segment of a plurality of road segments of an electronic map representing a geographic area around the first location. The coordination server determines a pickup side of the closest road segment based on the first location and the closest road segment. The coordination server sends, to a client device of a driver, a route to the first location such that the driver arrives on the pickup side of the closest road segment.
