Means over the seeds listed per variant. Time loss counts completed cohort trips only; elapsed time counts every scheduled car to its arrival or to the 09:00 horizon, so it does not hide unfinished trips.
Where these runs come from
Road network from OpenStreetMap (ODbL 1.0, via Overpass), netconvert; SUMO 1.22.0
15% of vehicles report their position every 30 s (SUMO floating-car output, geographic coordinates). time-to-teleport -1, ignore-junction-blocker 20, step 1 s, 06:30 to 09:00.
These are sensitivity runs on technical scenarios, not calibrated city forecasts. Every number on these pages comes from the recorded SUMO output; the site adds nothing.
