3.1 Intelligent Transportation Systems

Based on a relatively complete transportation infrastructure, and utilizing advanced information, communication, computer, automatic control, and system integration technologies, through...

Proprietary technologies such as traffic information collection (3.16) and fusion technology, traffic object interaction, and intelligent traffic control and management are used to enhance the capabilities of transportation vehicles.

The connection between carriers and users improves the operational efficiency of the transportation system, reduces traffic accidents, and lowers energy consumption and environmental pollution, thereby establishing a

A safe, efficient, convenient, environmentally friendly, and comfortable integrated transportation system.

3.2 Cooperative Intelligent Transportation System (cooperativeITS)

Intelligent transportation achieves intelligent collaboration and cooperation between vehicles and infrastructure, between vehicles, and between vehicles and people through the interaction of information between people, vehicles, and roads.

Transportation system (3.1) architecture.

3.3 Intelligent Transportation Systems (ITS) standard system

The basic standards, technical standards, service standards, product standards, and other standards related to intelligent transportation are arranged according to their inherent connections and logical relationships.

It is an organic whole formed by scientific integration, guiding the coordinated development, standardized construction and effective operation of intelligent transportation systems (3.1).

3.4 Intelligent Transportation System Architecture (ITS)

By linking the functional requirements of the intelligent transportation system (3.1) with the physical entities that carry these functions through information flow, a unified system is constructed.

Standardized framework structure.

Note. The intelligent transportation system framework consists of user services, logical framework, physical framework, support system, and key technologies.

3.5

An information platform that integrates, consolidates, and manages transportation-related information to provide comprehensive transportation services.

3.6

To improve the operation of the road network, a comprehensive perception and analysis of elements within the transportation system, including people, vehicles, transportation infrastructure, and the environment, is required.
