The present disclosure relates to a system and method for determining an optimized route for a carpool service. The method may include stringing a plurality of nodes to generate a plurality of first candidate paths. The method may also include determining a geographical length for each of the plurality of first candidate paths based on geographical distances between any two of the plurality of nodes. The method may also include determining one or more second candidate paths among the plurality of first candidate paths based on the geographical length for each of the plurality of first candidate path. The method may also include determining the navigation length for each of the one or more second candidate paths. The method may also include determining a target path among the one or more second candidate paths based on the navigation length.
