Systems and methods for providing information for an on-demand service

A system, comprising:

• at least one storage medium including a set of instructions;
• at least one processor in communication with the at least one storage medium, wherein when executing the set of instructions, the at least one processor is directed to:
• receive first electrical signals encoding service request information from a service requester, wherein the service request information includes a location of the service requester;
• operate a positioning engine in the at least one processor using one or more positioning technologies including GPS to determine an optimized original location of the service requester within a preset range from the original location;
• operate logical circuits in the at least one processor to determine a candidate meetup location set at least partially based on the optimized original location of the service requester, wherein the candidate meetup location set includes at least one candidate meetup location:
• generate second electrical signals encoding the candidate meetup location set to send to the service requester;
• receive, from the service requester, third electrical signals encoding processed data related to the candidate meetup location set;
• operate the positioning engine to evaluate the processed data including one or more processed candidate meetup locations, wherein the evaluation is made based on road conditions around the one or more processed candidate meetup locations, and relative orientations between the one or more processed candidate meetup locations and the destination of the service requester;
• operate the position engine to determine a final meetup location based at least in part on the evaluation;
• while service provider is driving toward to the final meetup location, the positioning engine is directed to:
• obtain preliminary positioning information of a passenger and the service provider by the one or more positioning technologies;
• send an instruction to a base station to turn on the station and send a broadcast signal when a distance between the service requester and the service provider is less than a certain threshold based on the preliminary positioning information;
• obtain broadcast signal strength between the service requester and the base station sent by the service requester;
• determine a distance between the passenger and the base station based on the broadcast signal strength;
• and
• send the distance to the service requester and the service provider.
