A method for estimating a travel time distribution of a taxi on urban roads when operating states of taxis are considered, which relates to the technical field of urban transportation planning and management. A route travel time distribution is estimated according to different operating states of a taxi, respectively. When a route travel time distribution is estimated, adjacent road segments in a road network are not independent. By describing a correlation between travel time distributions on the adjacent road segments by means of adding a Markov model, the scientificity and accuracy of the estimation results are improved. By setting a weight according to a ratio between the number of vehicles in two different operating states, a final route travel time distribution is obtained. Driving behaviors of a taxi driver would differ between a vacant operating state and a passenger-carrying operating state, thus a difference certainly exists between a travel time estimated by directly using taxi data and a real valu
