Car sharing method, system and server based on multiple taxies

The invention provides a car sharing method based on multiple taxies. The method includes the steps of obtaining starting point information and finishing point information of a first passenger of a first taxi and generating a first riding path, obtaining starting point information and finishing point information of a second passenger and generating a second riding path, calculating an overlapping path according to the first riding path and the second riding path, obtaining starting point information and finishing point information of a third passenger of a second taxi and generating a third path, and sending out car changing and sharing prompts if the third path and the overlapping path intersect and the finishing point information of the first passenger is in the third path. The method is easy to operate, can solve the problem that a lot of money and time are consumed on car sharing due to big differences of the destinations and allows the passengers of the taxies to change the taxies reasonably, taxi resources can be well mobilized, and cost of drivers and the passengers is reduced. Meanwhile, the invention provides a car sharing system and a server based on the taxies.
