study can be called in many fashions, such as origin destination
study, origin/destination study, origin & destination study. It
is short-formed as OD study, O-D study, O&D study or O/D study. Comprehensive
origin-destination studies (origin-destination surveys) are
usually for preparation of overall regional transportation studies.
An OD study can vary largely in scale due to its purpose. They are
conducted through personal interviews, mail interviews, license
plate tracking, tag-on-vehicle method, lights-on method, or most
recently, automatic license plate recognition (ALPR).
