Road surface estimation apparatus, road surface estimation method and program thereof

Abstract

Even when there is a plurality of road surface states within one geographical range or when there is a local road surface state, a road surface state is estimated with accuracy. Included are an aggregation unit (13, 15) that aggregates, on a per predetermined geographical unit basis, results of estimating road surface states using sensor data collected in advance for each of geographical ranges and including positional information obtained during travel of a moving object, the aggregation being based on the positional information, and an estimation unit (17) that estimates the road surface state for each of the geographical ranges and based on the estimation results aggregated by the aggregation unit.
