Methods and systems for providing transportation service to a passenger are disclosed. An exemplary method for providing transportation service may include receiving a transportation request from a terminal device, the transportation request indicating a passenger position. The method may further include causing the terminal device to search for network condition information associated with the passenger position. The method may also include determining, by at least one processor, a pick-up location for the transportation request based on the network condition information, and providing the pick-up location to the terminal device.
