Adaptive Traffic Signal



The Adaptive Stop Sign is a new stop sign converting the sign into a traffic signal during times of high-volume traffic and at other times as a standard stop sign. A small, sign mounted Traffic Signal Controller changes the signal lights and wirelessly communicates with other intersection signs, autonomous vehicles and monitoring facilities on signal and system status. A small sign mounted Traffic Flow Sensor System may be implemented for the detection of vehicle presence, location, speed, size and type of vehicle to maximize safety and traffic flow though intersections. The Adaptive Stop Sign could substantially improve intersection safety and efficiency, and reduce driver wait times, gas and frustration. Adaptive Stop Signs would be solar powered, quick and easy to install and maintain, and at a fraction of the cost of standard traffic control signals.

The Adaptive Traffic Signal is a new traffic signal implementing a large, bright, LED display panel with signal, timing status and animation to improve intersection safety and efficiency. The Adaptive Traffic Signal implements the small, wireless Traffic Signal Controller and Traffic Flow Sensor System mounted on the traffic signal (as described above). Intersection safety could be greatly enhanced with larger, brighter signal lights that can also display signal light timing status so driver’s see a countdown clock (or the like) to determine when the signal light will change.

The Adaptive Stop Sign is an enhanced stop sign that works as a traffic signal. The stop sign contains the word STOP, but includes lights that flash green, yellow and red in an active state for rush hour or heavy traffic and converts to a standard stop sign in an inactive state at other times.

The Adaptive Stop Sign includes a small, wireless Traffic Flow Sensor System and/or Traffic Signal Controller to monitor traffic conditions and use this information to control the signal light timing when active and turn the signal lights off when inactive, converting back to a standard stop sign. The Traffic Flow Sensor System consists of one or more cameras, lidar, and/or radar sensors or any combination, artificial intelligence (AI) and a unique neural network design to detect the presence, location, speed and type of vehicles approaching an intersection and wirelessly transmit this information to the Traffic Signal Controller to adaptively control the signal light timing. The Traffic Signal Controller would wirelessly transmit this signal light timing to other Adaptive Stop Signs for other directions and to autonomous vehicles and/or vehicles equipped for vehicle to vehicle communication to allow drivers to be notified of the signal light status within the vehicle. For example, if no traffic is detected in a direction, the opposing traffic signal light would stay Green. Or if a large truck or bus is approaching, particularly at a high rate of speed, the Green light for the truck’s direction would stay Green until the truck has left the intersection.

The Adaptive Traffic Signal includes similar wireless Traffic Flow Sensor System and/or Traffic Signal Controller (as above) but consists of a large, bright LED display panel that will not only provide the signal light, but can provide signal light countdown timer, and be animated in a way to draw driver attention and action, particularly as signal lights change from Yellow to Red with the intent of reducing intersection accidents.
