       Recent developments in traffic detectors include ones sensitive enough
to detect bicycles.  These are indicated by a white box outlining the detector
loop in the pavement.  Proper use is to ride the bicycle over the edge of the
box, not through the center.  Many unmarked detectors will respond to bicycles
if you locate the loop and align the bicycle wheel with the edge.  In stubborn
cases, laying the bike flat over the loop will usually trip it.

       Some recent work involves using signal processing equipment to 
distinguish cars, trucks, and buses from the loop signal alone.  First
use of this technology was in Germany.
