T/ITS 0217-2023 Digital expression technology specification for highway traffic flow

Scope

Main technical content: This document specifies the general requirements, application scenarios, data sets, and interface requirements for the digital expression of highway traffic flow trajectories, traffic events, and other state characteristics. This document is applicable to sensing and interactive devices deployed along highways, which continuously sense and acquire data such as vehicle locations, vehicle characteristics, traffic events, and traffic flow states. By integrating engines and platforms such as digital twins and data open service platforms, this document aims to achieve the digital expression of highway traffic flows and traffic events that affect traffic flow changes.
