arcroadWhat the detour costs

Directional estimate · not a measurement

What does crossing your own road cost you?

Pick the situation closest to yours, then move the sliders. Every number is an assumption you can change.

Your situation

Change any of these.

The trip

1.8 km

Starts at 1.75 km: the middle of arcroad's four matched city drives on 1 Nov 2026 (1.53 to 2.28 km beyond the straight line). Set it from a road you know.

2

The weakest input in the model. No public dataset gives this for Hyderabad.

300

365 for every day, about 250 for working days only.

1.0

Time is lost by everyone aboard; fuel is burned once.

The vehicle

Two-wheelers are about 73% of Telangana's fleet.

50

Real-world, not the manufacturer's claim.

₹116.15

Petrol, Hyderabad, 16 Oct 2026. Electricity is per kWh.

₹1.20/km

Tyres, servicing, depreciation. Set to zero to exclude.

Time

₹120

Zero shows fuel and wear alone, the floor nobody can argue with. Indian studies span about ₹50 to ₹600 an hour; see "Whose hour counts?".

14 km/h

Turns distance into time. 14 km/h is about the average of arcroad's matched city drives, waits at signals and U-turn queues included.

Over time

10 years

Medians outlast governments. A corridor built now is still there in 2040.

5.0%

Applied to fuel, wear and the value of time alike.

0.0%

Official appraisal discounts future costs. At 0% a future rupee counts the same as today's.

Exchange rates

₹91.0

Market rate. Set today's rate before quoting a dollar figure.

₹20.7

What a dollar buys in the US, priced in India.

Scale

50,000

No official count exists. Treat any group total as an order of magnitude, nothing finer.

What moves the answer

How much the yearly total swings if each input alone were halved or doubled. The top bar is where to attack this model first.

Whose hour counts?

Standard transport appraisal values travel time at wage rates. Applied here, an hour lost by a software engineer in Gachibowli is worth many times an hour lost by a construction worker in Pashamylaram, and the arithmetic then concludes the richer corridor deserves investment first. That is one way peripheral settlements end up last in the queue.

This page refuses to pick for you. Set the hourly value to zero and you see fuel and wear alone. Set it to a wage and you see the conventional appraisal figure. The gap between those two numbers is itself worth looking at.

What this is not

It is not a measurement. It is arithmetic on assumptions you chose, and it is only as strong as the weakest one: crossings per day, for which no public dataset exists for this city. Treat the single-person figure as directional and any group figure as an order of magnitude.

It leaves out tolls, congestion, roadworks, crashes and health damage, and it never puts a price on injury or death. It makes no claim about anyone's competence or motives.

Where the numbers come from
Extra distance and speed: arcroad's own drives, 1 Nov 2026
Four city passes that matched the model: 1.53 to 2.28 km beyond the straight line, 3 to 12 minutes each. The Outer Ring Road pass is left out because turning round there needs an interchange by design. Every pass.
Fuel prices, Hyderabad: petrol ₹116.15/L (16 Oct 2026); diesel ₹103.82/L and CNG ₹97/kg (25 Oct 2026, indicative)
Refreshed from the oil marketing companies' published rates before each release.
Tax inside the price: Telangana VAT 35.2% on petrol and 27% on diesel; central excise ₹21.90/L petrol and ₹17.80/L diesel
VAT rates set by the state in Feb 2015 and unchanged since, as widely reported. Excise from the oil companies' price build-up of Apr 2025, not yet re-verified for Oct 2026. VAT is levied on the price before VAT, so its share of the pump price is VAT ÷ (100 + VAT). CNG and electricity taxes are not modelled.
Value of time: about ₹50 to ₹600 an hour in Indian studies
A Delhi congestion-cost study (values for 2013, arXiv 1708.08984) and a Bengaluru congestion-pricing field experiment (Kreindler, J-PAL and IGC). Peer-reviewed or working papers; no single figure is official.
Fleet mix: about 73% two-wheelers
Telangana Transport Department figures as reported in May 2023: 1.13 crore two-wheelers of 1.54 crore vehicles statewide. Registrations are not road use.
Fuel economy: 50 km/L two-wheeler, 16 km/L petrol car, 20 km/L diesel car, 28 km/kg CNG auto, 40 km/kWh e-scooter, 6 km/kWh e-car
Typical real-world figures for the Indian fleet rather than manufacturer claims. Every one is adjustable.
Tailpipe carbon: 2.31 kg CO₂/L petrol, 2.68 diesel, 2.75 per kg CNG
Standard combustion factors. Electric vehicles show zero at the tailpipe, which is not zero emissions: grid generation is excluded.
India's GDP per person: ₹2,43,803 (FY2025-26, current prices)
Ministry of Statistics and Programme Implementation, with the IMF World Economic Outlook (Apr 2026) for the dollar and PPP figures.
Telangana: ₹4,20,347 GSDP per person (2024-25); GSDP ₹17,82,004 crore (2025-26, revised estimate)
