TRAVELLING ROAD INFORMATION ESTIMATION DEVICE AND TRAVELLING ROAD INFORMATION ESTIMATION METHOD

摘要

PROBLEM TO BE SOLVED: To solve the problem in which providing a technique making it possible to estimate a state of a travelling road with higher accuracy has been desired.SOLUTION: A travelling road information estimation device is provided that comprises: an acquisition unit that acquires a detection result including at least any one of a distance between the object and the sensor, and reception intensity in the sensor of a reflection wave from the object, and a speed of the object, on the basis of a beat signal to be obtained from a reception wave reflected by an object existing in a travelling road and received by a sensor; a tracking unit that, on the basis of the detection result and tracking data on each of a plurality of objects, associates the detection result with any of the plurality of objects to update the past detection result of each of the plurality of objects or the tracking data thereon; and a determination unit that determines a states of the travelling road on the basis of post-updated tracking data or the past detection result after updated.SELECTED DRAWING: Figure 1
