I have observed that there will be certain interchanges
that seem to have slow downs near them regardless of
the traffic volume.  There was one in particular that
seemed inexplicable till I noticed a feeling of
visual constriction approaching it -- if that caused everyone
to slow down slightly could this be enough to start a backup.

Is there anything other than anecdotes to support this idea?
