Data integration device, data integration method, and non-transitory computer-readable medium

A data integration method executed by a data integration device, comprising:

• acquiring a vehicle trajectory of a vehicle traveling on a road, the vehicle trajectory being extracted by an optical fiber sensor installed on the road;
• acquiring vehicle information on a vehicle traveling on the road, the vehicle information being detected by a roadside sensor installed on the road;
• and
• associating the vehicle information detected by the roadside sensor with the vehicle trajectory extracted by the optical fiber sensor.

A non-transitory computer-readable medium having stored therein a program causing a computer to execute:

• a procedure for acquiring a vehicle trajectory of a vehicle traveling on a road, the vehicle trajectory being extracted by an optical fiber sensor installed on the road;
• a procedure for acquiring vehicle information on a vehicle traveling on the road, the vehicle information being detected by a roadside sensor installed on the road;
• and
• a procedure for associating the vehicle information detected by the roadside sensor with the vehicle trajectory extracted by the optical fiber sensor.
