How we calculate this

We model fuel consumption as baseline × speed-multiplier, integrated over each hour of your trip. The multiplier comes from a curve calibrated against ARAI urban-cycle data (India), EPA fuel-economy speed corrections, and IIT congestion-emission studies. Free-flow uses the corridor's best-observed-hour speed.

Vehicle baselines (real-world urban L/100km at 50 km/h cruise): bike-petrol 2.5, car-petrol 6.5, car-diesel 5.5, auto-CNG 4.0, EV 10 kWh.

Cold-start: +50% fuel for the first 3 km. AC: +5% at speed, up to +12% in heavy stop-go. CO₂ factors: petrol 2.31, diesel 2.68, CNG 1.93 kg/L; EV uses India grid avg 0.71 kg/kWh (CEA 2024).

Estimates are within ±15% of measured fuel consumption for the modeled speed/vehicle combinations. We do not adjust for vehicle age, terrain, weather, or load.

How the math works

  • Hours stuck = daily km × (1 / actual avg speed − 1 / free-flow speed) × working days. Uses each city's measured network speed.
  • Fuel wasted = hours stuck × idle fuel rate for your vehicle type. Idle rates: bike 0.4 L/h, petrol car 0.6, diesel car 0.8, CNG auto 0.3, EV 0.
  • CO₂ emitted = fuel wasted × emission factor. Petrol 2.31 kg CO₂/L, diesel 2.68, CNG 1.97, electricity (EV) 0.7 kg/kWh × kWh-equivalent.
  • Money lost = fuel wasted × current pump price. Petrol ₹105/L, diesel ₹95/L, CNG ₹80/kg, electricity ₹20/kWh-equivalent.
  • Estimates have ±20% uncertainty — speed-up trims, idle vs creep mix, vehicle age. Use as directional, not exact.
