The invention discloses a method for evaluating the traffic state in the connection position of entrances and exits of an urban underground parking lot system. The method includes the steps of firstly, analyzing the traffic condition of the connection position of the entrances and exits of the underground parking lot system and an urban main road; secondly, establishing an evaluation index of the entrances and exits of the underground parking lot system, and calling a VISSIM program module to conduct traffic analogue simulation calculation according to indexes including the number and widths of the entrances and exits of the underground parking lot system, the length of ramps of the entrances and exits, the length and the lane width of an underground motor vehicle annular corridor, the underground parking berth number, the underground vehicle average speed, the underground parking time distribution and the like; thirdly, obtaining traffic situation evaluation data of all the entrances and exits of the underground parking lot system at different morning-evening peak hours, and conducting comparative analysis to obtain the change rules of the traffic state in the connection position of the entrances and exits. By means of the method, the design reference foundation is provided for reasonably designing and refitting the underground parking lot system and the entrances and exits of the underground parking lot system and improving the service level of the entrances and exits.
