Open Data
All data collected by SmartRoadSense users is released in aggregated form as Open Data.
The map available on this website just represents a possible visualization of SmartRoadSense data. We warmly invite users to develop and publish their own visualizations, eventually crossing our data with other datasets. If you do so or plan on doing so, please let us know.
What does the data mean?
The dataset is comprised of a single, compressed, CSV file. Road roughness data are provided as punctual data, each of them representing a 20-meters long portion of a road. Each data point has roughness value which is the average between all the data collected by users referring to that particular road section.
In addition to the roughness level information, each row of the dataset contains geographical and other data. The columns of the dataset are described below:
LATITUDE, the latitude coordinate at the center of the section of the road where the roughness value has been estimated,LONGITUDE, the longitude coordinate at the center of the section of the road where the roughness value has been estimated,PPE, the average roughness level of the road section,OSM_ID, the ID of the road in the OpenStreetMap dataset,HIGHWAY, the road category according to the OpenStreetMap classification,UPDATED_AT, the last update of the data for that particular road section.
Periodic updates
Both maps and Open Data are updated every 6 hours. Each new update differs from the previous one just by the data points associated with roads that have been travelled in the last 6 hours. The remaining part of the dataset stays the same.
Archiving
At the beginning of every week, the dataset is archived. New data is merged with archived data when computing up to date aggregated points. This procedure takes into account past informtion and makes it possible to reconstruct and to analyse the road network’s evolution in terms of roughness over time.
