Abstract:

According to the characteristics, planning principle and function orientation of the underground express- way serving middle- and long-distance transfers, this paper presents a depot choice model of underground express- way, and brings forward a point-line-surface planning way containing the processing of conventional 0D survey da- ta, the depot choice, the switching of OD table, the drawing of depot expectation figure and the coordinated plan- ning of the underground expressway. A case analysis is then performed. The results show that both the planning way and the depot choice model are theoretically valuable and practicably viable for the reasonable planning of un- derground expressway network.
