Scope: This document specifies the technical components and functional requirements of the digitalization of intelligent transportation infrastructure, including the technical requirements of functional integration application systems, digital support systems, and digital security systems. This document is applicable to the design and implementation of the core functions of national-level, provincial (autonomous region)-level, and city-level intelligent transportation infrastructure digitalization systems. Main technical content: National-level intelligent transportation infrastructure digitalization systems The basic functions of the national-level intelligent transportation infrastructure digitalization system include internal functions and external functions. 4.2.1.1 Internal functions The internal functions mainly include data integration, data analysis, and budget review and allocation. 4.2.1.1.1 Data integration Mainly responsible for integrating relevant data of national transportation infrastructure, including the following: a) The construction status of transportation infrastructure in different provinces (autonomous regions); b) Historical technical condition data of transportation infrastructure in different provinces (autonomous regions); c) Meteorological data in different provinces (autonomous regions); d) Dynamic traffic load data in different provinces (autonomous regions); e) Positioning data of transportation infrastructure in different provinces (autonomous regions). 4.2.1.1.2 Data analysis Carry out data mining within the national data scope and produce traffic infrastructure performance reports, and develop traffic infrastructure data analysis tools and models. 4.2.1.1.3 Budget review and allocation Mainly including the following: a) Review the budgets submitted by various provinces (autonomous regions) for transportation infrastructure construction, operation, and maintenance and assess the necessity of the
