Abstract:
A road management apparatus including a communication unit and a microprocessor. The microprocessor is configured to perform acquiring detection information via the communication unit, the detection information being information from a detection device mounted on each vehicle, and estimating a traveling lane on which each vehicle travels based on the detection information. The memory stores driving information including at least one of vehicle speed information and operation information of a direction indicator in association with the traveling lane, the driving information being obtained from the detection information acquired in each of a first period and a second period earlier than the first period. The microprocessor is configured to further perform estimating an occurrence of an abnormality on a road in the first period, in accordance with a degree of divergence between the driving information in the first period and the second period stored in the memory.
