🧭 Rider Flow Variables Clinic

Students translate earlier observation notes into a simple modeling setup for station movement. Using sketch paper, rulers, sticky notes, and a shared symbol key, they define variables such as entry points, bottleneck zones, sign placement, travel time, and decision points, then create a labeled draft before-and-after flow-map frame for an NYC station scenario. The class also establishes material-use and clean-up routines for cardboard, paper scraps, markers, and tape before prototype work begins.
