Lausanne, Switzerland (GenevaLunch) – Rush hour Monday evening on the A1 autoroute between Morges and Lausanne was a rare sight: traffic flowed, all three lanes of it in each direction. The extra new lanes, which function only when traffic demands it, were open, with new signage working, responding to real time traffic flow.

Several months of roadworks ended in December but the new system became operational early Monday and by day’s end traffic was flowing more smoothly than it has in years, at 18:00.
