Abstract: At present, there are more than 2 000 general speed railway stations, but only a few of these stations have built railway passenger service integration management platform ( Referred to: passenger service platform ) and the construction speed is slow. One of the main reasons is due to the complex of the train operation and the passenger transport organization at the general speed railway station, the existing management platform is not able to meet the needs of the existing passenger transport operations.Therefore, this paper studied and designed an intelligent train arrival-departure operation management system which was based on inbound throat intelligent video analysis and transportation dispatching management system(TDMS) access to nearby stations. The system could predict the state for the arrival and stop of trains. And on this basis, relying on c# programming language, new algorithm was implemented and designed. At the same time, through the comparison and analysis of the forecast results of the train arrival-departure operation time before and after the improvement of the on-site arrival-departure operation, the accuracy of time prediction by using the intelligent train arrival-departure operation management system is far higher than the arrival time prediction of existing service platform only receiving TDMS.
