Abstract: A transportation system between dispatchers and individual recipients includes a first transport-requirement device, a second transport-requirement device, a transport-execution device, and a data processing server. The first transport-requirement device and the second transport-requirement device respectively provides first plan information and second plan information, such information comprising start-locations of a first and a second plan, a destination-locations of the first and the second plan, and start-times of the first and the second plan. The transport-execution device provides driver information and driver confirmation of readiness. The data processing server provides carpool plans to the transport-execution device according to the driver locations. The data processing server obtains end-time of the first and the second plan according to the first and the second plan information, and generates carpool plans according to the relationship between first and the second plan information.
