1 Scope

GB/T 31455.1-2025 is the Chinese national standard covering the intelligent system of a BRT line as a whole - the dispatch centre, the vehicles, the stations and the signal priority, and how the subsystems relate to one another. Part 1 of the series. It replaces GB/T 31455.1-2015, one of four parts revised together. It was issued on 31 December 2025 and has been in force since 1 July 2026, replacing GB/T 31455.1-2015. The document is under the responsibility of the Standardization Administration of China. This page is published from the official record of the 2025 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the overall technical requirements for intelligent bus rapid transit systems, including the physical framework and business framework, as well as the internal requirements of each component. Requirements for tolerance and relationships. This document applies to the construction and management of intelligent bus rapid transit systems.
