An object is to holistically recognize a wide-area traffic condition in real time. A traffic monitoring apparatus (102) includes a position acquisition unit (106) that acquires position information indicating a vehicle position on a road, and a history generation unit (107) that generates history information indicating a change over time in the vehicle position, based on the position information. The position acquisition unit (106) acquires position information to be acquired, for example, based on optical fiber sensing utilizing an optical fiber being laid on a road. The traffic monitoring apparatus (102) may further include an abnormality detection unit (107) that detects an abnormal event on a road, based on an event-specific history pattern indicating a pattern of a change over time in a vehicle position associated with a type of the abnormal event on the road, and the change over time in the vehicle position.
