See a city network beside live traffic analysis
A current full-workspace recording of Traffic Flow Lab. Watch the built-in city network in the daylight 3D presentation beside its network controls and live operational metrics. The example shows congestion and review warnings; project use requires calibrated inputs and engineering review.
