Stalker Traffic Control Sensor
The Stalker Traffic Control Sensor monitors intersection approach traffic for signal control and motorist safety.
The Stalker Traffic Control Sensor improves intersection traffic control and enhances traffic safety at roadway intersections by intelligently controlling traffic signal timing based on vehicle speed and distance.
The Stalker Traffic Control Sensor has greater than 500 foot range (152.4 m) and monitors traffic approaching an intersection using Applied Concepts’ Advanced Radar technology. Radar technology provides operation in all weather conditions and is more
reliable, less expensive, and more flexible than traditional video camera systems,
buried loop systems, or buried wireless sensor systems. In addition, the equipment is easily moved to other locations.The sensors are easy to install and can operate stand-alone or with the existing traffic intersection control systems when paired with an Applied Concept’s traffic control card.
Vehicles in a multi-lane zone are tracked, then analyzed for speed and distance to compute time until crossing the Stop Bar.
Based on its computations, the Stalker Traffic Control Sensor can:
Notify the intersection’s traffic light system of approaching
traffic, allowing the system to extend the duration of the green light cycle for that direction, if necessary.Extend the typical 1-second “all red” signal time in the intersection
for accident reduction. The speed and distance of all approaching
vehicles is used to compute their respective “time to intersection”.
