中国智能运输系统体系框架National ITS System Architecture of China
全国智能运输系统专家委员会National ITS Committee of Experts
1. China Needs and needs her own ITS
1.1 China Needs ITS
By the end of 1999, China has:• Population: Over 1.3 billion, No.1 in the World• Highway: Over 1.4 million Km, No.4 in the World• Freeway:11,605 Km, No.3 in the World• Traffic Accident:Over 80,000 people dead, No.1 in the world• Vehicles: Over 50 million• Railway: Busiest in the World• Resource: Natural Resource per capita, Out of No.50 in the
World
- There are none system can fit all the country.
- China Can not Copy developed countries’ ITS.
- Unbalanced development of ITS in China.
- National ITS should conform to government management system.
1.2 China Needs her Own ITS
Table of Government Functions
Related to Transportation Title of ministries Main functions
Ministry of railway Planning, constructing, operating and
maintenance of railway infrastructure
Ministry of communications Planning, constructing, maintenance of
highways and water channels; transport

2. How develop China’s ITS
Government’s Consider:
- ITS System Architecture
- ITS Standards
- ITS Development Strategy and Deployment Plan
3. ITS System Architecture of China
3.1 Significance:- Overall contents and relationship between different parts of
national ITS development are specified and national compatibility and investment benefits are guaranteed.
- Formulation of the system architecture will make ITS into focal point in society.
- Formulation of the system architecture will designate the positions and roles of government, enterprises and users in ITS deployment.
3.2 Main objectives:
-Identify the whole demands for national ITS.
-Confirm the feature of national ITS system architecture.
-Analysis technical and economical factors which affect national ITS development.
3.3 Main parts of nationalITS system architecture
Part 1: Users, Service providers.
Part 2: User services
Part 3: Logical architecture
Part 4: Physical architecture
Part 5: Communication Infrastructure and GIS-T Data Exchange Platform.
Part 6: ITS standards
Part 7: Evaluation.
Relationships between different parts of ITS and services
Title Functions
Users Identifying the objects of user
services
Service providers Identifying service providers and
service receivers
User services Indicating what kind of services
system can provide
System functions Transferring services into system
specified objectives
Logical architecture Service organizing
Physical architecture Identifying the ways of service
providing
Communication Infrastructure and
GIS-T Data Exchange Platform
Intelligent Transports Infrastructure
for applying services
ITS standards and evaluation Technical and Economical factors
4.2 Focus on the User Services
4.3 Research Methods
• Process-Oriented Methodology
-typically US and Europe
-China use this method.
• Object-Oriented Methodology
-Japan and Australia
4.4 The technical route of studying ITS system architecture of China
1. Determine the content of user services
