Tuas Crossing

A live + forecast dashboard for the Tuas Second Link outbound (Singapore → Johor Bahru) crossing.

• Now — live corridor speed bands (AYE / Tuas Viaduct / Tuas Second Crossing), predicted AYE → Tuas Checkpoint travel time, incidents, and live traffic camera stills.
• When to cross — a day × hour heatmap built from accumulated history.

How it works

• GET /api/live — travel time, cameras, and incidents come live from LTA DataMall server-side (the API key lives only as the DATAMALL_KEY Space secret), cached ~60s. The corridor speed bands are read from the public dataset (the laptop collector is the single client of LTA's heavy v4/TrafficSpeedBands feed), shown with their age.
• GET /api/history — reads the public companion dataset CSVs and aggregates average speed band by (day-of-week, hour).
• GET /api/freshness — newest collected-sample age, for the stale-data badge.

Data source: LTA DataMall. History is collected on a private always-on machine and pushed to a public Hugging Face Dataset.

The DataMall key is never exposed to the client — it is used only server-side.
