| Abstract: | In recent years, the transportation capacity of Shuohuang Railway, an important coal transportation corridor in China, has become saturated. To exploit potentialities and raise efficiency, transportation organization optimization is the key way in the short term. Based on elaborating the present situation of traffic volume on the Shuozhou-Huanghua railway, the traffic volume of 2030 is predicted by the time series method, which is found that under the condition of existing equipment and transportation organization, the railroad capacity is not able to meet the transportation demand. This paper analyzes the technical conditions under the traffic volume target of 450 million tons and proposes the phased optimization steps of transportation organization on the Shuozhou-Huanghua railway from two aspects of station operation efficiency and train transportation organization based on a new type of automatic parking device. A series of optimization measures for capacity expansion and efficiency improvement are raised, such as dwell time compression of cargo at the station, skylight influence area compression and interval parking mode on skylight day. It is found that when the proportion of 20,000 tons of trains reaches more than 60%, the Shuozhou-Huanghua railway can achieve the volume target of 450 million tons. The compression of the skylight influence area could add 197 additional trains of 20,000 tons every year. And the interval parking mode could increase the annual capacity by about 690,000 tons. |
