The accuracy and reliability of the SmartSensor line makes these sensors an excellent choice for supplying an adaptive system with the traffic data it needs to do its job. And with each SmartSensor performing a different function in traffic detection, you’ll always be able to find a sensor that provides the sort of detection data that your adaptive system needs.
Let’s look at some of those data requirements and how those needs can be met with high-quality data from Wavetronix SmartSensors.
Many adaptive systems require detection some distance upstream from the intersection, reporting on vehicles approaching that intersection from some distance away. In this case, you can use SmartSensor HD at a midblock installation; this sensor’s dual-radar configuration and patented Digital Wave Radar provide highly accurate detections and speeds for up to 22 individual lanes of traffic.
Another option for detection in advance of the stop bar is the SmartSensor Advance. This sensor can detect vehicles approaching from 600 feet away — 900, if you get the Advance Extended Range. Using this sensor, you can get your data without having to trench out to a midblock location, saving you time and money.
Your adaptive system may require queue length information to decide how much time a given movement needs in order to clear out a queue. For that, consider the SmartSensor Matrix. Its simple and flexible configuration process allows you to create up to sixteen zones as easily as the click of a mouse. To estimate how far back a queue stretches, make zones that are set back some distance from the stop bar.
Some systems look for occupancy information, using the amount of time a zone or loop is occupied to calculate how full and how slow the road is getting. SmartSensor Matrix can help you get that information at the stop bar. Its patented Radar Vision process detects even those vehicles that are at a dead stop, thereby providing true presence detection. And its zones can be easily adjusted in the software to be any quadrilateral shape and any size (that falls within the sensor’s 140-ft. field of view).
If your adaptive system requires counts at an intersection, SmartSensor Matrix has you covered. The easy-to-use SmartSensor Manager Matrix software includes a counting channel option that makes it a snap to set up counting zones and channels.
DID YOU KNOW?
Intersections with lots of zones and channels can have a downside: the more channels you need to send to the controller, the more contact closure cards you may have to buy. But there are alternatives! The Click 65x series features handy multipurpose devices; in addition to providing up to four or six SmartSensor Matrix and/or Advance units with power, surge protection and communications, they can also be used to send detection data to a traffic controller without the use of contact closure devices, provided your controller supports SDLC communications.
