Description (English):

This document specifies the general framework and the automated driving bus (ADB) system components for operating ADBs in public transport networks, including: a) the general framework and the operation scheme for public transport systems in cooperation with ADBs; b) definitions of system components for operating ADBs; and c) definitions of functions and requirements of each system component for providing transport services with ADBs. This document is applicable to bodies in public transport systems and services including transportation operators, public transport governing authorities and relevant industries.

Abstract

Overview

ISO 21734-1:2022 - part of the ISO 21734 series - defines a general framework for performance testing of connectivity and safety functions for automated driving buses (ADB) in public transport. Published in 2022, this International Standard describes the ADB system components, their functions and requirements, and the operation scheme for ADBs (SAE level 4 or higher) operating within public transit networks. It forms the basis for developing test methods and performance procedures that ensure safe, connected ADB services.

Key topics and technical requirements

ADB system components: clear definitions and roles for the ADB itself and supporting elements such as the monitoring and control (MC) centre, IoT infrastructure, smart bus stations, and ADB user components.
Safety aspects: requirements for operation safety and safety functions that enable ADBs to respond to pedestrians, bicyclists and unexpected events while providing public transport services.
Connectivity aspects: requirements to ensure reliable connectivity between ADBs and traffic signal networks, MC centres and roadside infrastructure; emphasis on maintaining the information feed required for safe operation.
Data sets and service information: specification of the transport information needed for operations (e.g., signal status, boarding/alighting data, bus priority signals, roadside signage, energy/battery status).
Use cases and scenarios: structured reference use cases for operational testing including intersections (left/right turns, straight), crosswalks (signalized and non-signalized), and bus stop/station scenarios (with/without bay).
Framework requirements: component-level requirements for safety, connectivity and service operation to guide public authorities, operators and vendors in system design and testing.
Note: ISO 21734-1:2022 contains no normative references and is the general framework (Part 1) for the wider ISO 21734 series.

Practical applications

Developing national or local performance test procedures for ADB deployments.
Designing interoperability and connectivity testing between buses, traffic signals and monitoring centres.
Defining minimum safety requirements and validation criteria for public transport ADB operations.
Informing procurement, pilot projects and system integration for automated transit services.

Who should use this standard

Public transport operators and transit agencies
Public transport governing authorities and regulators
Vehicle OEMs, suppliers and system integrators implementing ADB solutions
Test laboratories and certification bodies developing ADB performance tests
