The OpenStreetMap road network with structural chokepoint scores and a data-quality layer, Bengaluru Traffic Police signal timings,
and an open, no-account review of where each timed junction really is. No traffic simulation yet: open data has no vehicle counts.

Timed junction (BTP)
Click a junction dot on the map. Colours: green = verified by reviewers, blue = in review, amber/red = unreviewed (medium/low automatic match). Junctions without an automatic location are not drawn yet.
No account needed. Each contribution needs a few seconds of proof-of-work, and is appended to a public hash-chained log.
We store a salted hash of your IP and browser (not the IP) to count distinct reviewers and limit spam.
A location becomes "verified" when at least 3 different reviewers agree and they are 75% of reviewers on that junction.
Contributions are released under ODbL 1.0.
Limits
Chokepoint score = how many fastest routes use a road segment (sampled betweenness, 1,000 sources) on speeds osmnx assumes from road class. It is a structural measure, not measured congestion.
No open vehicle counts exist for Bengaluru, so nothing here predicts queues or delays. A calibrated simulation needs counts (e.g. one corridor) first.
Lane counts are tagged on only part of the network (see data quality); untagged roads use assumptions.
BTP timing PDFs carry no licence statement. Shown with credit; originals linked. 3 PDFs are scanned and not parsed; rows that fail the phases + pedestrian = cycle check are marked.
Junction locations are automatic guesses until reviewers verify them. The guess is from the junction name only.
