摘要： 综合列车运行图的时间-位置、列车运行控制的位置-速度两种模型的优点，提出一种能够更精确描述列车运行状态和运行轨迹的时间-速度-位置模型（TVP模型），并分析模型的特性。结合列车多质点模型，明确列车质点相关的安全区域、可达区域、协同区域的边界和特点，给出列车安全可达区域的范围。从运输组织、调度指挥、运行控制、控制调度一体化等多个方面总结梳理该模型适用的应用领域。

关键词: 列车运行状态, 时间-速度-位置模型, 安全性, 可达性, 协同性

Abstract: A time-velocity-position model (TVP model) is proposed to describe train operation status and trajectory in a more accurate way together with an analysis of the characteristics of the model. This model combines the advantages of the time-position model for train graphs and the position-speed model for train control. Based on the multiple-particle model of a train, the boundary and characteristics of the safe area, the reachable area and the cooperative area related to the train particles are identified, and the range of the safe and reachable area is determined. The applicable fields of the model are summarized in terms of transportation organization, dispatching command, operation control and the integration of control and dispatching.

Key words: train operation status, time-velocity-position model, safety, reachability, cooperativeness
