Why I built it

Dense-city movement is a useful test bed for combining exploratory data work with clear operational interfaces.

Problem being solved

Raw traffic and routing data is difficult to reason about without a view that exposes patterns, constraints, and change over time.

Key challenges

• Cleaning and shaping time-dependent traffic data.
• Comparing forecasting approaches without hiding uncertainty.
• Translating model output into scenarios a person can inspect.

Design decisions

• Separate exploratory notebooks from presentation-oriented views.
• Keep routes and time windows as the primary comparison dimensions.
• Present forecasts as decision support rather than certainty.
