Abstract: Urban underground roads construction is an effective measure to solve urban traffic congestion problem. However, the planning and construction of urban underground roads lag behind the urban ground construction; the location selection of the underground road ramp entrances/exits is difficult, the ramp rehabilitation cost is high, and the limited ground road resources are depleted, which brings inconvenience to ground transportation. Therefore, the setting status of underground road ramp entrances/exits and Evan Masque′s elevatortype ramp are analyzed, and a new design plan for ramp setting of urban underground roads, i. e. intelligent contro tidal ramp(elevatortype ramp) entrance/exit is proposed. The ramp entrance/exit can be opened and closed intelligently according to ground traffic flow monitoring data. The feasibility analysis focuses on intelligent control management system, recommended design parameters, safety verification of the lift ramp, cost calculation, and traffic efficiency of the plan. The results show that the intelligent control tidal ramp for urban underground road is characteriazed by low cost, high safety, flexible locationselection, and high efficiency.

Key words: urban underground road, ramp entrance/exit; intelligent control, tidal ramp
