Dunno if you’re in America but here’s a site with a map of **known** flock cameras if you want to check if that one is part of the network https://deflock.org/

I have no proof, but I suspect some of them will identify your car by your ezpass. (a brief pause) Did a search, and yup. You're carrying a tracking device, of course they are going to use it to track you https://www.aclu.org/news/privacy-technology/newly-obtained-records-reveal-extensive-monitoring-e-zpass

The white brick at the bottom is for detecting large objects (cars) and is either controlling a traffic signal, or is being used to count traffic going through that spot. An intersection near me uses them to switch the lights at an intersection where traffic almost never comes from, so a timed light is unnecessary, but important traffic still comes from that direction.

I work for a company that makes security cameras and we also make radars as a supplement to the cameras. The purpose of the radar is to tell PTZ cameras where objects are so they can pan/rotate to the correct spot as quickly as possible. In this case these look like fixed cameras so I don’t think it’s a radar. I would assume, considering the climate these cameras are in that this is some kind of weather sensor. Considering the size of it, it probably has a few features to it.

Road guy Rob has a video that came out yesterday and in it they discuss the bottom one being a radar alternative for loops in the ground for cars to change the lights.

A quick search for "traffic sensor" returns a whole class of items that all basically look like the rectangular brick in your photo. Supported by the temporary / construction look of the one in the other comment. Construction company puts in a lane restriction or other traffic modification, plop down a traffic sensor to make sure cars are still flowing through properly.

Looks cold, a thermite module would help.

Btw, the white box in a supermarket ceiling is to ID you and track your movement based on your phone.

From left to right, top to bottom: 2 fixed box cameras (most likely 2 generations of ALPRs: an older (larger/yellowed: which they won't bother removing, and instead keep for redundancy), and a newer (more capable) model), a 'Pan Tilt Zoom (PTZ)', and what appears to be a radar sensor (for detecting objects: possibly serving as a redundancy, during challenging weather conditions). I suspect the radar sensor got installed first (just for perimeter intrusion detection), they added the old ALPR next (to detect patterns in registered license plates); and the rest as an upgrade (including an increased field of view: through the PTZ's movable head).
