"Centro European Multimodal Road Roughness (CE-MRR) Dataset"

"This dataset aims to determine road conditions focusing on low-cost alternatives to dedicated survey vehicles, three different data sources were selected and used in parallel for data collection: A GNSS receiver with IMU mounted in a vehicle; a smartphone running two different apps to measure the IRI (Internationa Roughness Index); and the subjective perception of road quality assessed by the passengers inside the vehicle. Three data sources were collected at the same time along highways and interurban roads in a round trip between Austria, Hungary, and Romania. The trip covered approximately 1700km and lasted 30 hours, with the recording activated 25% of the duration of the trip. The datasets were collected in segments of 12-15 minutes of continuous recording for a total of 7 hours and 10 TB of data recorded. Vehicle operation was conducted under normal traffic conditions and in compliance with local traffic regulations. The diversity in road types and countries ensures variability in pavement quality, structural characteristics, and environmental conditions. "
