Technical specifications for the construction of
intelligent traffic management system
1 Scope
This standard specifies the composition and technical requirements of the
intelligent traffic management system.
This standard applies to the planning, design, construction of intelligent traffic
management systems in provinces (autonomous regions, municipalities),
districted cities, counties (cities).

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Intelligent traffic management system
Public security traffic command system
It is a system, which uses intelligent traffic technology and methods to
manage road traffic; has the function of traffic command, traffic control, traffic
law enforcement, traffic information service.
3.2
Integrated application platform
An application software system, which integrates road traffic monitoring,
decision-making, control, service.
3.3
Application support system
of the sub-command center, the front-end supporting fundamental facilities.
3.7
Front end
Equipment and related ancillary facilities, which are installed on roads and
other places, for traffic control, traffic law enforcement, traffic information
collection and release.
4 General rules
4.1 Classification of intelligent traffic management system
The intelligent traffic management system is divided into two types: provincial
(autonomous region) intelligent traffic management system AND urban
intelligent traffic management system, according to the different central
management authority and core tasks. The structure diagram is as shown in
Appendix A. For expressways directly managed by municipalities, counties
(cities) and provinces (autonomous regions), it should be constructed with
reference to the urban intelligent traffic management systems.
4.2 General rules
The construction rules of the intelligent traffic management system are as
follows:
a) The planning shall meet the requirements of GA/T 1403;
b) The design shall meet the requirements of GA/T 515;
c) The project construction process shall meet the requirements of GA/T 651;
d) The front-end settings shall meet the requirements of GB 14886, GA/T
993, GA/T 1047, etc.;
e) Front-end maintenance shall meet the requirements of GA/T 1043;
f) For other construction content, please refer to the relevant standards in
Appendix B.
The construction rules of the traffic management data resource management
system are as follows:
a) It should use big data and cloud computing technology framework;
b) It shall construct a unified and standardized basic hardware resource, that
meets the requirements of data volume and computing power;
c) There shall be standardized interfaces and interactive protocols, which are
suitable for different systems;
d) It shall adopt standard data format and exchange interface;
e) Data shall be cleaned, repaired, classified, correlated, stored, etc., to
ensure data specification and data quality;
f) Classified preprocessing and storage of traffic management data
resources, including structured data, unstructured data, semi-structured
data;
g) Unified planning of information resources and classified construction of
various thematic data resource libraries, classified display of data storage
time;
h) It shall be equipped with data analysis tools for custom production of
various business application model libraries;
i) There shall be technical measures and mechanism requirements for data
security, data backup and recovery.
6.1.3.1.2 Data interaction
It mainly realizes data exchange with the following systems:
a) Higher-level public security organs;
b) Urban intelligent traffic management system in the province (autonomous
region);
c) Relevant departments in the province (autonomous region);
d) Internet companies;
e) Intelligent traffic management system of neighboring provinces
(autonomous regions);
f) Related systems in the public security network;
g) Related systems in the private network;
6.1.4.1 Communication system
6.1.4.1.1 General rules
