Controlling Traffic Signals TRIZ Cases
- Federated Traffic Signal Control for Diverse Intersection Conditions
Federated and reinforcement learning adapts roadside traffic signals to varied intersections while aggregating model parameters across servers.
- Roadway Intersection Capacity Visualization With Dequeue Zones
Phase timing and turn-movement data create dequeue-zone and queue visuals, helping users compare intersection supply with demand.
- Roundabout Light Scale Safety System for Vehicle Speed Detection
Sensors detect vehicle speed and direction, while a curb-embedded light array gives entering drivers real-time roundabout safety cues.
- Infrastructure Radio Wave Sensor for Adaptive Crossing Signals
Radio reflections identify stopped vehicles, traffic volume, and sudden crossing events to adapt pedestrian light control.
- Influence-Based Traffic Rule Control Server for Vehicle Groups
Using predicted vehicle movements, the server calculates group influence and controls traffic displays so higher-impact groups can continue traveling.
- Segmented LED Traffic Lights for Predictable Signal Transitions
Sequentially extinguished LED sections give drivers advance warning of traffic signal changes, helping reduce confusion and accidents.
- Base-Station Cluster Departure Detection for Vulnerable Road Users
Centralized base-station monitoring detects a vulnerable road user leaving a cluster and sends warnings without shifting processing to mobile terminals.
- Road-Section Traffic Volume Estimation Using Signal Timing Data
Traditional sensors can miss intersection blind areas; feature data and signal timing support closed-flow accumulation for accurate road-section volumes.
- Railroad Crossing Warning Light Monitoring for Traffic Coordination
A camera-based warning light monitor shares railroad crossing status with traffic controllers to reduce unnecessary vehicle-flow disruptions.
