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

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.

4. Methodology

4.1 Why needs a system architecture

Relationships between different parts of ITS and services

Title Functions

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
