Implementation of Train Interval Protection in Train Autonomous Circumambulate System
Kongzhi Yu Xinxi Jishu, 2022 Train interval protection is an important protective function to ensure the safe operation of trains. In the traditional communication-based train control (CBTC) system, line resources in the route are centrally managed through the fixed interlocking ...

Research on urban rail train control system based on train to train communication
Journal of Physics: Conference Series, 2022 Abstract The new train control system VBTC based on train to train communication adopts the idea of on-board centralization, regards switches and sections as trackside resources, integrates the functions of interlocking and zone controller into on-board, and the train independently manages line resources and determines the train ...

ITS-G5 Channel Models for High Speed Train-to-Train Communication [PDF]
, 2017 Train-to-train communication will be the key technology for future railway operation. An increase of safety and efficiency can be achieved by exchanging data between trains via ad hoc networks. For vehicle-to-vehicle communication the European standard is intelligent transport systems (ITS-G5).

Dependability checking with StoCharts: Is train radio reliable enough for trains? [PDF]
, 2004 Performance, dependability and quality of service (QoS) are prime aspects of the UML modelling domain. To capture these aspects effectively in the design phase, we have recently proposed STOCHARTS, a conservative extension of UML statechart diagrams.
