Border Waiting Times Aggregation and Visualization
Since mid of 2018 I have been collecting and aggregating the border waiting times between Slovenia and Croatia and since 2019 I also collect the border waiting times from Austria to Germany. The source for the waiting times between Croatia and Slovenia is the Croatian automobile club HAK and the source for the Austrian waiting times is Asfinag (Austrian highway company).
With the aggregated data it is possible to see at which points in time a border checkpoint is usually heavily frequented. It's then possible to plan one's own journey according to the expected waiting times. Both HAK and Asfinag only offer live waiting times without the possibility to look back in time. Thus, I created an aggregated view of their data which then allows to check the waiting times throughout the year.
The data is available at traffic.stefan-koch.name with a delay of approx. one hour.
