Effect analysis on railway productivity distribution adjustment to freight forwarding time

摘要

In order to analyze the effects of railway productivity distribution adjustment on the timeliness of freight forwarding, on the basis of investigation and present achievement, the railway freight forwarding process and the change of each factor which affects freight forwarding time under the condition of railway productivity distribution adjustment are analyzed. The average speed of each kind of freight train including non-through train, ordinary through train and fast freight train, as well as daily average running time of heavy train is analyzed, and the statistical results are examined by adopting χ² testing method, from which daily average running tariff kilometre is obtained. Finally, daily average running tariff kilometre before and after railway productivity distribution adjustment is compared. The analytical results show that through the adjustment of railway productivity distribution, the operating taches of railway freight forwarding gradually reduce, and the primary parameters influencing θ all have changes to different degree, and the timeliness of railway freight forwarding improves constantly.
