How much is Ahmedabad traffic costing you?

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 Ahmedabad's citywide average (37.3 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 Ahmedabad'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.
