Space-Time Networks Construction Analysis Based on Railway Wagon-Flow Adjustment

Abstract

Railway wagon-flow organization and adjustment are connected and influenced each other, and solve mainly the problem of the departure trains on every route direction in railway network and absorbed wagon-flows by every train-flow. The change of railway wagon-flow organization and the problem need to be solved in recent years were analyzed. On the basis of previous research, the construction method of space-time network was described on basis of physical network that has already definite traveling time and the two parameters including time and station. The construction of space-time network based on the characteristic of railway wagon-flow adjustment helps to catch the dynamic characteristic in the course of freight transportation. It laid the foundation for constructing model of railway wagon-flow organization and adjustment.
