Cooperative intelligent transportation systems -
Dedicated short range communications - Part 1:
General technical requirement
1 Scope
This Part of GB/T 31024 specifies the object communication relationship and
dedicated short range communication reference architecture of the cooperative
ITS, the main intelligent transportation system services that are supported by
the dedicated short range communication, the requirements of the dedicated
short range communication technology, the requirements of the dedicated short
range communication equipment, the security requirements and time
management, etc.
This Part applies to the design, development, operation, and maintenance of
dedicated short range communication subsystem applications in cooperative
intelligent transportation systems; it is the basis for formulating technical
implementation standards, quality evaluation standards, and engineering
standards for dedicated short range communication applications in cooperative
ITS.
2 Terms and definitions
The following terms and definitions are applicable to this document.
2.1 Cooperative ITS
An intelligent transportation system that realizes intelligent coordination and
cooperation between vehicles and infrastructure, vehicles and vehicles, and
vehicles and people through information interaction between people, vehicles
and roads.
2.2 Dedicated short range communication
The wireless communication method with limited communication distance
between vehicles and vehicles, vehicles and infrastructure, infrastructure and
infrastructure, which is one of the basic communication methods in the field of
intelligent transportation systems.
2.3 On board unit
a) Vehicle-assisted driving, which includes assistant driving and road
infrastructure status warnings:
1) Assisted driving: early warning of collision risk (especially at the
intersection), wrong driving method warning, signal violation warning,
slow vehicle instruction, motorcycle approaching instruction, vehicle
remote service, pedestrian monitoring, collaborative automatic platoon;
2) Road infrastructure status warnings: vehicle accidents, road
engineering warning, traffic condition warning, weather conditions and
warnings, and infrastructure status abnormal warning.
b) Transportation safety, including emergency rescue requests and
responses, emergency notifications, emergency vehicle scheduling and
priority traffic, safety monitoring of transportation vehicles and drivers,
overload and over-limit management, and safety protection of vulnerable
groups of traffic.
c) Traffic management, including traffic regulations notification, traffic law
enforcement, signal priority, guidance on the best speed of traffic lights,
parking lot management.
d) Navigation and traffic information services, including real-time route
guidance and navigation, construction areas, tolls, parking lots, transfers,
traffic event information, flow monitoring, suggested itineraries, and
notification of points of interest.
e) Electronic toll collection, which includes charging users, in the means of
transaction, for transportation-related expenses, such as road, bridge and
tunnel tolls, road congestion fees, paid traffic information service fees,
parking fees, and route identification.
f) Transportation management, including transportation administration
inspection, special transportation monitoring, fleet management, station
management, etc.
g) Others, including vehicle software/ data configuration and update, vehicle
and RSU data calibration, collaborative sensing information update and
transmission.
c) The capacity of concurrent end-users that are supported by the road side
unit shall be greater than 128.
6.3 Technical requirements for the network layer
6.3.1 The network layer can be adapted to different physical layers. The
network layer shall have backward compatibility to support systems such as
electronic non-parking tolls and forward scalability.
6.3.2 The cooperative ITS communication application can fully utilize various
network resources to meet the cooperative ITS application requirements under
complex traffic scenarios, through business characteristics such as mobility,
communication mode, authentication, processing mode, data rate, security,
reliability, and interactivity.
Its main technical requirements are as follows:
a) Strong mobility support: the maximum speed of the supported terminal's
movement is not less than 120 km/h; when the road side equipment
coverage area is crossed, the business continuity can be guaranteed;
b) Delay requirements: the end-to-end transmission delay of safety
emergency shall be less than 50 ms;
c) It can support multiple access technology requirements; the network layer
and the application layer are relatively independent from the access layer
technology. It can provide services to the network layer through multiple
access technologies; for example, the electronic non-parking tolls and
dedicated short range communication system can use the same network
and application layer for information interaction with the business service
platform;
d) It supports the diversity of transmission technologies; the network layer is
relatively independent from the data transmission technology. For
example, the data transmission from the central subsystem to the RSU
can be transmitted through fiber optic network or twisted-pair, and the
network layer is not affected by the underlying transmission technology;
e) Quality of service (QoS) guarantee, which can establish priorities for
services and have QoS identification capabilities to support the network's
QoS guarantee mechanism.
6.4 Technical requirements for the application layer
The application layer mainly includes vehicle-to-vehicle communication
applications, vehicle-to-road communication applications, and other general
through the signal coverage that is defined by rules, and stop repetition or
cancel event message sending through a special event;
n) broadcast cooperation messages periodically and at a given frequency.
8 Security requirements
8.1 General security
Cooperative intelligent transportation dedicated short range communication
systems shall adopt the necessary information security technology to ensure
that the system's data security and user privacy are not leaked.
8.2 Data security
The data security of the cooperative intelligent transportation dedicated short
range communication system mainly includes data storage security and data
transmission security.
The system shall take necessary access control, confidentiality control, and
integrity verification measures to ensure that data is not be stolen, forged,
tampered with or destroyed during storage and transmission.
8.3 Privacy protection
The cooperative intelligent transportation short range communication system
shall protect the privacy of all parties in the system on the premise of complying
with relevant national laws and systems.
9 Time management
9.1 The time management support equipment maintains the global time
reference for timestamps data elements.
9.2 The time management support equipment will extract Greenwich Mean
Time from the receiver of the Global Navigation Satellite System, to synchronize
the local real-time time, and add timestamps data at the end of the message
formatting process.
9.3 The time management support equipment has the ability to maintain an
accurate global clock.
9.4 The time management support equipment has the ability to calculate the
maximum delay time during transmission.
