AI-Generated Review

What is stockholms-puls?

Stockholms Puls delivers a realtids-3D-visualisering of Stockholms tunnelbana, pulling live train positions from Trafiklab GTFS-RT or a built-in simulator to render glowing tunnels, particle trains, and activity-scaled stations under a transparent city grid. Click stations for departure boards with ETAs, trains for status and follow-cam, and get AI-analys commentary every 45 seconds via OpenRouter on traffic puls like delays or crowds. Built in TypeScript with React Three Fiber for the 3D scene and Node/Express WebSockets for real-time streaming, it runs locally with `npm run dev`—no API keys needed for basics.

Why is it gaining traction?

It stands out with smooth 3D depth views (exaggerated tunnels, surface columns), flow pulses along lines, and alert halos, turning raw GTFS data into an intuitive dashboard that reveals Stockholms puls better than flat maps. The AI-analys adds narrative summaries, predictions, and mood indicators (calm to stressed), while replay mode lets you scrub history. Devs dig the fallback simulator and optional basemap toggle for instant demos without external data.

Who should use this?

Frontend devs exploring React Three Fiber for geospatial viz, transit hackers integrating GTFS-RT streams, or Stockholm locals monitoring SL tunnelbana disruptions. Ideal for side projects like custom Stockholms puls reklam displays or ai-analys prototypes with live med puls data.

Verdict

Grab it for a polished 3D transit viz starter—MIT licensed, solid README with env setup, runs out-of-box. At 18 stars and 1.0% credibility score, it's an early gem but lacks tests and broad regions; fork and extend for production. (198 words)
