Description
Built with GPT-6 Astra in Codex, Counterfactual is a transport experiment lab where ideas face reproducible tests. Discover why a shortcut can slow everyone down, design custom networks, search road closures and upgrades, and challenge results across traffic levels. Inspect the math and export the evidence. The public demo runs deterministic simulations; live Astra hypothesis generation is optional and not connected in this release.

Could you build this?
Partial A web interface visualizing traffic networks is simple to prototype, but accurate microscopic or macroscopic counterfactual traffic flow simulation (e.g., demonstrating Braess's paradox with equilibrium math) relies on specialized transport algorithms.
What it would actually take: The stack would involve a Python or C++ simulation engine (such as SUMO or custom network equilibrium solvers computing Wardrop's user equilibrium) paired with a reactive frontend (React, Deck.gl/Mapbox). The hard part is implementing robust, convergent traffic assignment algorithms that accurately model network dynamics, congestion games, and elastic demand. This requires transport engineering and mathematical optimization expertise to ensure simulations reflect valid game-theoretic outcomes rather than simplistic heuristics.
