GB/T 43758.2-2024Technical specifications for driving safety test environment for intelligent and connected vehicles - Part 2: Semi-open road (English PDF)

Foreword

This document was issued on 31 December 2024 by the State Administration for Market Regulation; Standardization Administration of the PRC and takes effect on 1 July 2025.

It is a GB/T standard: recommended rather than compulsory, but it is the text a Chinese reviewer applies when assessing a submission.

1 Scope

GB/T 43758.2-2024 specifies the semi-open road test environment for intelligent and connected vehicles, the second stage of the Chinese autonomous vehicle testing ladder between the closed proving ground and the public road. The semi-open road is the environment in which a system meets real traffic, pedestrians and weather while the operator still controls access, and its value depends entirely on it being specified rather than improvised: a test result is only transferable if the road environment it was obtained in is defined. The standard sets the requirements on the road environment, its geometry, surface, markings and boundaries, on the traffic facilities, signs, signals and roadside units, on the traffic control and the management of access and of other road users, on the road lighting and the environmental conditions, and on the monitoring, communication and data recording infrastructure that the test requires, together with the safety measures and the emergency arrangements. It takes effect on 1 July 2025.

This document specifies the requirements for the road environment, traffic facilities,

traffic control, road lighting, traffic operation, road monitoring and communication, and

test assurance of semi-open roads used for operational safety testing of intelligent

connected vehicles.

This document is applicable to the selection, construction and determination of semi-

open roads for safety testing of intelligent connected vehicles at level 3 driving

automation (conditional autonomous driving) and above as specified in GB/T 40429-

2021.It is also used as a reference for the selection, construction and determination of

semi-open roads required for demonstration applications of intelligent connected

vehicles.
