Short poles - we have traffic-cams around here (Long Island), but they
are mounted on long poles. Some websites let you view traffic
conditions from these cams, and I suppose the traffic controls centers
use them to determine the messages to display on the Intelligent
Traffic Systems and what-not.
Short poles, I dunno, air quality sensors?

Are you on or near near any toll roads that use EZ-Pass or similar?

I see these alot in the Orlando area on the expressways and on near by
city streets - the boxes look almost exactly like the antennas used in
the toll facilities there to read the E-Pass/Sunpass transponders. My
guess is they are used to determine where cars are going after they
exit the freeways and/or to measure speed on the freeways.

If they're only over the right two lanes, and there's an inspection or weigh
station within 2-3 miles after each one, they're PrePass or NorPass
transmitters/receivers. Those are systems used to tell truckers whether they
have to come in for inspection.

If they don't have a visible lens, they might be traffic.com's
sensors. Though around here traffic.com uses solar power and 900Mhz
wireless.
