How much is Kolkata traffic costing you?

Punch in your commute. We'll tell you how many hours and how much money you lose every year — measured against real Kolkata road speeds, not Google guesses.

Built on live road data in partnership with Kolkata Traffic Police.

How we calculated it

Four inputs, four steps. Every number below is measured, not modelled.

Distance. Google Maps returns the real driving distance between your home and office — not a straight line, not a city grid approximation.
Route-specific speed. We locate every TraffiCure-measured road segment within 300 m of your route and pull its hour-by-hour average speed. A highway commute uses highway speeds; an inner-city route uses inner-city speeds. If we don't have segments near your route yet, we fall back to Kolkata's citywide average (28 km/h free-flow).
Rolling-hour travel time. A 20 km trip at 9 AM crosses into the 10 AM hour. We walk your route forward hour by hour, applying each hour's measured speed to the minutes you actually spend in it.
Delay. (time at your hour) − (time at free-flow). Computed separately for morning and evening because Kolkata's evening rush is sharper than its morning rush.
Annualised. (morning delay + evening delay) × days/week × 50 weeks × your ₹/hour.

Accuracy is roughly ±20% on the final number. What we can't see: your specific lane choices, parking-lot exits, signal cycles, and whether you get lucky. What we can see: how fast the roads themselves are flowing, which is the part the city can change.
