25 vehicles on a one-lane ring road (1 km circumference, drawn unrolled), under four deliberately different published car-following models. Every model and every number shown runs in frozen Glon Alpha; this page only schedules ticks, loads a model's source the first time it is selected, paints the canvas, and shows the status Glon emits. See GLON-TRAFFIC-MODELS.md for the model comparison.
Brake disturbance: vehicle 0 is speed-capped for a window near the start of the run, then normal dynamics resume (NaSch instead forces a full stop -- see the model comparison doc for why). Vehicle 0 is drawn in red.
Pacing (IDM only): vehicle 24 (the disturbed vehicle's immediate follower) is speed-capped at 18 m/s from the moment the brake begins -- see GLON-TRAFFIC-MODELS.md for why this does not (and is not claimed to) generalize to the other three models. Switching model or scenario resets the experiment.
