Sources & Data

No black boxes. Every number on Toraffic.ca traces back to an open, published source. This is the map of it all: where the data comes from, the raw datasets you can browse and download, and the analysis we build on top of them.

Where the data comes from

Primary source Live · daily to 30 min

City of Toronto Open Data Portal

The engine behind our road restrictions, CaféTO patios, cycling network, traffic signals, intersection and midblock counts, and ward boundaries. Datasets are synced on each source's published cadence (road restrictions every ~30 minutes; counts weekly).

Routing engine (OSRM)

Self-hosted OSRM on the OpenStreetMap Ontario extract (Geofabrik, refreshed weekly). Each route is computed twice (with and without disruption penalties), and the delta is attributed per source.

MAPBOX DIRECTIONS (THIS MONTH)

No live measurements yet. Add a MAPBOX_TOKEN to enable live-traffic comparison alongside OSRM.

Impact Score

A derived 0 to 100 estimate per ~200 m grid tile, blending active restrictions, CaféTO curb-lane patios, movement counts, and signal density. An estimate, not measured.

Transit Projects

Metrolinx and TTC megaproject impacts, derived from road-restriction records filed under those agencies' contractors, not a GTFS (General Transit Feed Specification) feed.

Historical archives

Decades of intersection turning-movement counts (1984 to present) and midblock speed/volume counts (1989 to present), refreshed monthly. Each location's detail page renders a time-series of the available studies. Aggregated at the study level; the City does not publish raw bucket-level history.

Estimates labelled as estimatesRouting penalties and the impact score are estimates, not measured travel time, and are marked as such throughout.
