The invention relates to an urban road network vehicle path estimation method based on a deep recursion Logit model. The method comprises the following steps: step 1, acquiring track data of urban road network vehicles; 2, initializing an iteration round and parameters of a utility function in the deep recursion Logit model; 3, calculating a loss function based on the trajectory data and the parameters; 4, carrying out gradient calculation to obtain an updating direction; 5, the step length of the next round is calculated, the parameters are further updated, and the updated parameters are obtained; 6, judging whether a convergence condition is met or not, if yes, outputting the updated parameters, and if not, returning to the step 2 to carry out iterative calculation according to the step length of the next round until the convergence condition is met; and step 7, estimating the urban road network vehicle path according to the optimal parameter to obtain an estimation result. Compared with the prior art, the method has the advantages of improving the estimation precision of the vehicle path and the like.
