Document Type and Number:
Japanese Patent JP7225303
Kind Code:
B2
Abstract:
To perform an accident forecast with high accuracy even for a road with large installation intervals of sensors.SOLUTION: In an accident forecast system in an embodiment, a table creation processing part for an accident forecast creates a table for the accident forecast representing an accident occurrence degree for every traffic situation based on predetermined learning algorithm by using at least past traffic data regarding a vehicle, and past accident data for a predetermined spot on a road. A traffic data acquisition processing part acquires present traffic data from sensors which measure traffic situations. A traffic situation estimation processing part sets an estimation spot where the traffic situations are desired to be estimated on the road, and estimates the traffic situations at the estimation spot based on a ratio of each distance from a plurality of predetermined sensors to the estimation spot by using the present traffic data acquired from the plurality of predetermined sensors. An accident forecast processing part forecasts the accident occurrence degree by using the traffic situations estimated by the traffic situation estimation processing part, and the table for the accident forecast for the estimation spot.SELECTED DRAWING: Figure 1
