Influence analysis of transport capacity loss for out-of-gauge freight trains running on single-track railway
摘要
Abstract
Through taking the process of multi-train movement on single automatic block section as the research object, accord-ing to the running characteristic that freight trains should obey while operating in single-track section and the theory of CA, this paper proposed the concepts of train equivalent, stop cellular and overtaking cellular. On the basis of the running process of train in the district, proposed many kinds of transformation rules. Analyzed the cellular state of the out-of-gauge train before and after overtaking. Constructed train running simulation model of single-track section based on CA, and built evaluation general model of single-rail transportation capacity loss for the running of out-of-gauge train. Designed the corresponding heuristic algo-rithm for solving model, simulated running process of trains on single-track section through computer, depicted the loss charac-teristics of capacity caused by running of out-of-gauge trains, which evaluated the capacity loss of railway transportation. Simu-lation results show that models and algorithms put forward can evaluate capacity loss caused by running of out-of-gauge freight train effectively, and also analyze the adverse influence of single-rail transport capacity caused by mixed running of trains with various speeds and their transfer effect legitimately.关键词
