Data underlying the publication: Speed behaviour upon approaching freeway curves

High Frequency Floating Car Data was collected to analyse circa 1 million individual speed profiles on 153 Dutch freeway curves. By defining the positions where the acceleration approaches 0 m/s2 before and after a curve starts, the positions when the driver started and stopped decelerating upon curve entry were defined. These positions and speeds are put in a database, combined with detailed reconstruction of the curves and their surroundings, as well as three dimensional sight distance analysis. This aggregated database is shared here, along a file explaining the different variables in the database.<br>More backgrounds can be read in:<br>Vos, J., Farah, H., &amp; Hagenzieker, M. (2021).
