NordicWay 2 aims at enhancing traffic safety through Cooperative Intelligent Transport Systems (C-ITS). The project is European Commission Connecting Europe Facility-funded between 2017 and 2020, and it is implemented by the National Road Authorities of Finland, Norway, Sweden and Denmark as well as private companies and research centres.
In Finland, the Finnish Transport Agency is implementing the NordicWay2 project’s Finnish activities together with the Finnish Transport Safety Agency Trafi. The project is also part of the Finnish Traffic Lab collaboration. The Finnish deployment of the project comprises two activities: the C-ITS deployment pilot and the Arctic Challenge study concerning road transport automation in arctic snowy and icy conditions.

Bridge vibrations (expired)
Aurora is a public test ecosystem created to ensure intelligent and automated transport as well as solutions for road maintenance and asset management to meet the requirements of all conditions. A part of Aurora ecosystem is an experiment measuring the vibrations of bridges.
Data is unit-less acceleration values which correspond to measured voltage values from the measurement devices. As such it is suitable for example to make frequency analysis over time.
Each file contains 1 minute worth of data (32 kHz sample frequency, 4 bytes per sample, little endian, binary). File name is in the pattern AL1501962095, where A = Identifier of the measurement-card, L = Channel ( L or R ) and 1501962095 = the file create time stamp (epoch, seconds).
Average file size is about 7 megabytes.
