New York State has deployed a traffic monitoring system on select interstates and parkways. You can see them in the medians. They consist of pressure treated wooden poles with a device mounted on top. There are also a small solar panels on top for charging the units. Look closely in the medians and you will see them. This system was designed to monitor traffic speed and volume. It’s apparently being used to detect speeders for the police. It will alert to a high speed vehicle and send an alert to the nearest patrol. It’s not a speed camera but it let’s them know when a speeder is coming.
