Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of railway vehicle flow estimation, and in particular to a method and device for estimating railway vehicle flow in real time. Background Art
[0002] Railway transportation is a key link connecting economic regions, and its efficiency directly affects the circulation of materials and economic development. Traffic flow estimation involves the processing and prediction of train information. Through data collection, storage, transmission and calculation, traffic flow information is processed, and based on the train's en route and at the station, different business processing methods are used to obtain short-, medium- and long-term traffic flow forecasts. Accurate traffic flow estimation is crucial to the preparation of railway transportation plans, especially under the unified dispatch of the entire railway, which is of great significance to improving freight efficiency and reducing costs.
[0003] Traditional methods for estimating railway traffic usually rely on historical data and empirical rules for prediction. These methods are mainly based on past operating data, such as train schedules, actual operating time, train marshaling plans, and station arrival and departure times, and derive traffic distribution patterns through statistical analysis. On this basis, some static or quasi-static models are used to estimate future traffic conditions. This method usually requires manual participation and relies on statistical data within a fixed time window. Although traditional traffic estimation methods are simple and easy to use, they also have inevitable defects.
[0004] On the one hand, the traditional method cannot reflect the current actual operation status in time, especially in the face of emergencies (such as natural disasters, equipment failures, etc.), and its prediction accuracy will drop significantly. On the other hand, the traditional method does not analyze the time of trains at the station, fails to analyze the operation time when the train passes through the station in detail, and ignores the situation that the train does not perform relevant operations or stop at the station, which causes a large error in the traffic flow estimation work. In addition, the traditional method often relies on fixed models and algorithms, which is difficult to adjust flexibly according to the actual situation. It fails to analyze the efficiency of railway train operation and the efficiency of train handover at the boundary, and cannot accurately estimate the railway traffic, nor can it make real-time corrections to the estimated results of the railway traffic, and cannot ensure the accuracy of the traffic flow estimation.
