Traffic Pulse Screensaver
The Traffic Pulse screensaver shows a live congestion index for a handful of major routes in a chosen city, computed from real current drive-time estimates against an off-peak baseline — key-less, via the OSRM open routing engine. It's free, runs in your browser, and ESC exits.

How the Traffic Pulse screensaver works
The saver requests real current drive-time estimates for fixed routes in your chosen city from the OSRM routing engine.
Each route's current time is compared to its free-flow baseline to compute a live congestion percentage.
Routes are shown as gauges that fill more as real congestion increases.
Readings refresh on a schedule to track how traffic actually changes through the day.
A worked example
Set it to Toronto during rush hour and the downtown routes swing toward heavy congestion — a real comparison against the same route's free-flow time, not a fixed animation.
Settings & tips
- City switches the set of tracked routes.
- Accent recolours the congestion gauges.
- The routing engine is a public demo service — occasional slow responses are normal.
Frequently asked questions
- Is this official traffic data?
- No official live traffic index is free and key-less; this computes a genuine proxy from real routing-engine drive times.
- Is a key needed?
- No. The OSRM public routing service is free and key-less.
- Which cities are covered?
- A small built-in set of major cities with fixed representative routes.
- Is it free?
- Yes — free, no download, in your browser.
