The invention relates to a universal method for flow and demand prediction of shared travel. The method comprises the following steps: S1, obtaining a topological structure and a travel mode of an urban traffic network; s2, establishing a traffic flow conservation constraint and a ride-sharing matching constraint; s3, establishing a generalized travel cost function; s4, constructing a generalized random ride-sharing user equalization problem; s5, establishing an elastic demand function, and constructing a generalized random ride-sharing user equalization problem with an elastic demand; s6, constructing a fixed point model containing parameters; s7, constructing a variational inequality model equivalent to the generalized random ride-sharing user equalization problem; and S8, introducing a projection method, a Monte Carlo simulation method and a weighted cost averaging method, and designing a calculation method of the variational inequality model. According to the method, data input is simple, the method can be used for multiple types of shared traffic users, behavior selection models, demand models and shared traffic services, and simultaneous prediction of flow and demands of multiple types of shared traffic networks can be realized.
