Cooperative Intelligent Transport Systems (C-ITS)
System Architecture
C-ITS employs a unique layered architecture that differs from traditional ISO OSI model by enabling direct cross-layer communication.
Key Architectural Features
- Flexible Design: Adaptable to various implementation needs
- Open Platform: Supports interoperability and third-party integration
- Abstract Framework: Provides high-level system organization
- Cross-layer Optimization: Enables direct information flow between layers
- Future-proof Structure: Designed to accommodate emerging technologies
Cross-layer Communication
Unlike the traditional ISO OSI model, C-ITS allows:
- Direct information transfer between non-adjacent layers
- Reduced encoding/decoding overhead
- Efficient data flow from lower to upper layers
V2X (Vehicle-to-Everything) Implementation Phases
Phase 1: Awareness Driving
Initial stage focusing on basic vehicle awareness and communication
Phase 2: Sensing Driving
Enhanced environmental perception and response capabilities
Phase 3: Cooperative Driving
Vehicles begin working together through coordinated actions
Phase 4: Synchronized Cooperative Driving
Advanced coordination enabling precise vehicle synchronization
Phase 5: Accident Free Driving
Ultimate goal of achieving zero accidents through complete system integration
