Travel time calculator
A drive leg by leg, with the stops and the traffic in it.
It runs entirely in this browser tab: nothing you type is uploaded, and it makes no request of any kind.
Settings
- Leaving at
- As 09:30. Empty leaves the arrival out.
- A break every
- In hours of driving. Nought leaves the stops out. A number from 0 to 6.
- Break length
- Twenty minutes is a coffee; forty is lunch. A number from 5 to 60.
- Traffic adds
- A percentage on every leg. A city on a Friday is not the same road. A number from 0 to 60.
How to use it
- Paste your text into the box above, or open a file.
- Adjust the settings beside it until the result is what you wanted.
- Copy the result, or save it as a file. The result updates as you type.
Questions
- Where do the coverage rates and densities come from?
- They are the published typical figures — what a tin of emulsion claims, what a cubic metre of dry sand weighs, what a bag of screed covers. They are printed on the result so you can compare them with the bag in front of you, and the bag wins.
- Is the ten per cent reserve part of the calculation?
- No, and that is why it is a setting. It is a trade convention for breakage and offcuts, and the quantity without it is shown on the same result, so you can order either.
- Can I use this instead of a heating engineer or a structural check?
- No. A heat loss from six fields is an order of magnitude, not a design: a standard calculation takes every room, orientation and junction separately. The snow tool weighs snow; whether your roof carries it is on its drawings.
- Does anything I type here leave the page?
- No. There is no account, no server and no network request. What you type stays in this tab, and in the link if you choose to share one.
