Planning Graph Heuristics for Belief Space Search

open access: yes, 2011
Some recent works in conditional planning have proposed reachability heuristics to improve planner scalability, but many lack a formal description of the properties of their distance estimates.

Research on Failure Processing of Axle Counter in CBTC System

open access: yesChengshi guidao jiaotong yanjiu
Objective The communication-based train control (CBTC) system usually uses the axle counter to provide train auxiliary positioning functions. However, in the case of axle counter failure, if it is always processed as "occupied", the system operating ...

Autonomous Train Control System Principle: Fully Train‐Centric Route Generation and Track Resource Management

open access: yesIET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
This study proposes a principle for an autonomous train control system (ATCS) where trains manage track resources, generate routes, and control trackside objects without relying on wayside controllers. Using Super Balise Groups (SBG) and directed graphs, the system simplifies route generation through factorization and composition, while a new braking ...
