Problems solved by technology
Based on the unified station data, the network topology map of the arrival throat area of the station is established, and the train operation simulation model is established at the same time. The train operation simulation is combined with the calculation of the arrival interval, and the arrival interval between different pairs of lanes is automatically calculated through the computer, and an intuitive Graphical results can solve the problem of heavy workload and error-prone manual calculation, and provide practical tools for assisting in the compilation of operating diagrams and rational use of station lanes by dispatchers

The invention relates to a system and method for calculating the arrival interval of rail transit stations. The present invention replaces the traditional train arrival interval with the stop point of the station as the reference point with the continuous receiving interval at the station, simplifies the complex train interval model by introducing the concept of restriction point and release point, and determines the calculation model of the arrival interval at the station , establish the topological map of the station arrival throat network, use the path search algorithm to determine the parallel routes between the relative tracks, and use the algorithm design to identify and eliminate unreachable paths, avoiding the workload and error rate of manual identification.
Description
technical field [0001] The invention relates to the technical field of rail transit, in particular to the technical field of station arrival interval calculation. Background technique [0002] The arrival interval of rail transit stations, especially the arrival interval of large stations, is the key factor restricting the travel interval. With the improvement of the automation degree of station interlocking equipment, unlocking of routes by sections has become a commonly used technical condition. Based on this technical condition, the The calculation of the arrival interval has become a realistic demand. Analyzing the factors that limit the passing capacity of the station and reasonably calculating the arrival interval of the station have practical significance for evaluating the passing ability and guiding traffic; There are a large number of lanes occupied by the front and rear trains, that is, the number of permutations and combinations of lane pairs is very large, and s...
