Controlling Traffic Signals TRIZ Cases

Video-based traffic control systems adjust signal timing dynamically to resolve static schedule inefficiencies and reduce idle emissions.

A smartphone-based system lets pedestrians request dynamic crosswalks that trigger autonomous vehicles to stop at selected locations.

Synchronizing display operation with traffic signal cycles reduces power consumption while maintaining advertising effectiveness for captive audiences.

A driving support device estimates vehicle motion using initial position and speed data to provide guidance through intersections.

A traffic light assistance system displays vehicle symbols relative to signal phase information on an integrated dashboard interface.

User equipment switches communication protocols based on speed thresholds to manage bandwidth allocation.

Predicting traffic patterns from image sequences optimizes signal timing, reducing congestion and wait times.

Segmenting processing into master and slave processors distributes thermal load to maintain reliability under heavy sensing burdens.

GPS vehicle detection replaces underground sensors to reduce maintenance costs while optimizing traffic flow through dynamic signal timing.

Traffic control unit reserves dedicated lanes via indication messages, resolving warning notification delays that hinder emergency vehicle passage.

A traffic management system processes inter-party right-of-way requests using GPS data to adjust signal timing dynamically.

Wireless beacons triangulate user position and speed to adjust crosswalk signals, resolving fixed timing delays for pedestrians with unique needs.

Target speed adjustments on a single lane mitigate downstream congestion without requiring full lane blockage or excessive vehicle fleets.

Kalman filtering estimates queuing vehicles on boundary links while Macroscopic Fundamental Diagram modeling predicts regional accumulation to prevent overflow.
