System composition of intelligent transportation

Intelligent Transportation System (ITS) is the development direction of future transportation system. It effectively integrates advanced science and technology (information technology, computer technology, data communication technology, sensor technology, electronic control technology, automatic control theory, operational research, artificial intelligence and so on). ) Access to transportation, service control and vehicle manufacturing has strengthened the relationship among vehicles, roads and users, thus forming a guarantee.

The application scope of ITS includes airport and station passenger flow guidance system, urban traffic intelligent dispatching system, expressway intelligent dispatching system, operating vehicle dispatching management system, automatic motor vehicle control system, etc.

Composition of intelligent transportation system;

1, traffic information collection system: manual input, GPS car navigator, GPS navigation mobile phone, vehicle traffic electronic information card, CCTV camera, infrared radar detectors, coil detector, optical detector, etc.

2. Information processing and analysis system: information server, expert system, GIS application system, manual decision-making, etc.

3. Information distribution system: Internet, mobile phone, vehicle terminal, broadcasting, roadside broadcasting, electronic information board, telephone service desk, etc.

The function of intelligent transportation system: through the harmonious and close cooperation among people, vehicles and roads, improve transportation efficiency, alleviate traffic congestion, improve road network capacity, reduce traffic accidents, reduce energy consumption and reduce environmental pollution.

Intelligent transportation system refers to a system that integrates electronics, information, communication, control, vehicles, machinery and other technologies, and can quickly, flexibly and correctly understand and propose solutions to improve traffic conditions and maximize traffic efficiency. Intelligent system is a complex system composed of intelligent system, knowledge system, method and skill system, non-intelligent system, conceptual thinking system and evaluation system.
