Cooperative Intelligence for Heavy Commercial Vehicles

Overview

Heavy commercial vehicles (HCVs) present disproportionate safety risk due to mass, braking distance, blind spots, maneuverability constraints, and extended duty cycles. These characteristics increase the impact of delayed hazard perception and delayed mitigation.

Why HCV Safety Needs a New Approach

Existing approaches can be effective but often incomplete when isolated:

Local-only ADAS is constrained by sensing horizon and line-of-sight
Cloud-only telematics provides fleet-level oversight but may be too delayed for sub-second intervention
Corridor-level hazards can emerge beyond a single vehicle's observation boundary

Research Contribution

This is a comparative architecture research paper rather than a pure model-accuracy paper.
The key contribution is a proposed three-layer cooperative architecture that combines:

Vehicle edge intelligence
V2X cooperative hazard exchange
Cloud-based fleet-level prediction and policy feedback

Proposed Architecture

1) Vehicle Edge Layer

Local sensor fusion
Real-time risk scoring
Immediate mitigation actions

2) V2X Communication Layer

V2V, V2I, and V2N hazard exchange
Upstream hazard dissemination
Corridor context propagation

3) Cloud Intelligence Layer

Fleet-level forecasting
Policy and model refinement
Cross-vehicle trend learning

Risk Scoring Concept

The risk function combines:

Vehicle state
Environment state
Cooperative context from neighboring vehicles and infrastructure

This supports a context-enriched mitigation strategy beyond isolated local inference.

Experimental Setup

Study conditions include:

50 HCVs with mixed passenger traffic
Urban-highway topology
Braking-wave scenarios
Low-friction roadway segments
Night-time fatigue conditions
Downhill grade plus load combinations
Comparative baselines: local-only ADAS, cloud-only telematics, and cooperative architecture

Results

Under simulation-based evaluation:

Cooperative configuration achieved approximately 61% earlier hazard detection versus local-only baseline
Approximately 46% fewer near-collision events versus local-only baseline
Cooperative mitigation latency around 110 ms
Cloud-only latency around 620 ms, less suitable for sub-second intervention

These results are simulation-based and should be interpreted as architectural feasibility, not deployment proof.

Limitations

Current limitations include:

Simulation-based evaluation only
No real-world fleet telemetry validation yet
No hardware-in-the-loop validation
Potential need for calibration across fleet types and geographies
