1. IntroductionThe origin–destination matrix (OD matrix) reflects the expected movement intensity of road users, where each element is the number of trips between the two traffic analysis zones (TAZs). It can represent the traffic demand over different time scales, from hours to years, corresponding to the dynamic and static OD inference problem, respectively.
