ADAPTIVE TRAFFIC CONTROL
Developement of Electronically Controlled Traffic Flows
Take the first exit which is called Winterthur-Töss if you come from Zurich. Otherwise take the last exit, like indicated on the map below.
You can see a star on the map. This is a red light camera, indicating as well the only traffic light you should encounter. Turn right at the light and enter the 40 km/h speed limit zone. Climb up the hill and drive down the hill.
At the end of the hill the 40 km/h speed limit zone ends. And that's exactly the place where you have to turn to the left. Park in front of the second building at the left. You have found ATC.
