T/JSAS 131-2026 Construction,operation and maintenance of intelligent connected intersections

Scope

This document provides recommendations for the classification of intelligent connected intersections and sets forth requirements for the construction and operation and maintenance of intelligent connected intersections. This document is applicable to guiding the construction and operation and maintenance of intelligent connected intersections. Intelligent connected intersections Intelligent connected intersections are intelligent road nodes (hereinafter referred to as "intersections") in urban and rural road networks, where multiple directions of roads converge, integrating roadside sensing, communication, and edge computing capabilities to achieve collaborative interaction among people, vehicles, roads, and clouds. 3.2 On-board units Functional entities installed in vehicles that are equipped with information collection, processing, storage, input, and output interfaces and have dedicated short-range wireless communication modules. [Source: GB/T 31024.1—2014, Section 2.3] 3.3 Roadside sensing equipment Equipment deployed on the roadside for sensing traffic participants, traffic events, traffic flow states, and other traffic information. 3.4 Traffic incidents Events caused by the sudden disruption of normal traffic order due to the lack of coordination among people, vehicles, facilities, and the environment. [Source: GB/T 20839—2025, Section 10.1] 3.5 Sensory perceptual system A system composed of computing facilities, sensing equipment, and related ancillary equipment used for real-time sensing of the traffic environment. 3.6 Edge computing system A distributed computing and service platform deployed at roadside or regional locations to provide low latency, high bandwidth, and localized processing capabilities for vehicle-road-cloud integrated systems. It is a core component of the vehicle-road-cloud integrated architecture, connecting to roadside units and roadside sensing equipment at the lower level and collaborating with
