T/GDITS 004-2025 Operational Specifications for UAV Inspection in Expressway Administration

Scope

This standard specifies the technical content of highway road administration drone inspection operations, including inspection system requirements, inspection operation requirements, inspection content, pre-inspection preparation, inspection methods, inspection modes, organization and transfer of inspection data, and handling of abnormal situations. This standard applies to the use of rotary-wing drones (including automatic takeoff and landing airfield-style rotary-wing drones) for highway road administration inspections (including bridge control areas, bridge underpasses, building control areas, construction sites, road surfaces, and surrounding environments). It serves as an effective supplement to traditional manual inspections. The applicability of drones for highway road administration inspections is shown in Table 1, where "feasible" indicates that drones can independently collect information for inspection content, and "auxiliary" indicates that drone operations still require human law enforcement intervention or secondary verification. The purpose of this specification is to establish norms for highway road administration drone inspection operations, with the aim of standardizing and guiding the efficient and safe application of drone technology in highway road administration inspections. By clarifying the components of the inspection system, inspection operation requirements, and inspection methods, this specification standardizes the highway drone inspection process and promotes the transformation and upgrading of highway road administration management from traditional models to intelligent and digital ones. The main technical content is as follows: （1）Scope: Describes the main technical content of the standard and defines its applicable scope. （2）Normative references: Describes the documents that can be referenced in the standard preparation process. （3）Terms and definitions: Mainly refers to one or more concepts with specific meanings in the
