Tomtom One is always inaccurate when calculating arrival time. On longer trips, say 1 to 3 hours, its about 30 minutes too high at the start. On shorter trips, say 20 minutes to 45 minutes, its about 10 minutes too high. As I proceed, it constantly lessens the arrival time until I get to my destination, at which time it is correct. That doesn't help when planning a trip, though. This has nothing to do with a certain area. In the last 2 weeks, this GPS has been in Canada and the US, and its the same everywhere.
Thats normal- estimate is always higher the units go by speed limits and you shave time off trip units adjust accordingly

I suggest any unit under warranty to be returned to its supplier or if they will not help, contact tomtom directly!

It is possible that you have the TomTom set for "walking routes" or "bicycle routes" or "limited speed." (I have a TomTom One 3rd edition, so if you have a different model the menus/icons may be different, but it's worth a shot.)
Click on the main part of the screen, while on the main navigation screen. Then click on "Change preferences." Then click the blue arrow to scroll to the Preferences 3 of 5 page. Click on "Planning preferences." Choose the planning preferences that you want. Hope this helps...
SOURCE: error during planning
The most usual reason for this is a corrupted map. Try reloading the map. This certainly worked for me.

Try to reset device by using a paperclip or similar at bottom of unit...
SOURCE: Tomtom1 keeps restarting itself
try resetting it, if that doesnt work, connect your unit to tomtom
home. if you dont have tomtom home, follow the link at the bottom.
To reset your TomTom device, do the following:
Charge your device for at least 2 hours before trying to turn it on again. Make sure the charging light on your device is on.
If your device uses an SD card, remove it.
Use a straightened paper clip, or something similar, to push the reset
button for 15 seconds. See the pictures below for where to find the
reset button.
Press the On/off button for at least 5 seconds.
If your device uses an SD card, insert the SD card.

I have two Tomtoms - a brand new Tomtom One 3rd edition I got for my birthday on April 5th, and Tomtom One XL-S I just bought refurbished from Amazon with the intention of giving to my girlfriend.
My 3rd edition is great with arrival times. The refurbished XL-S I just got, however, is way off! Example: I set both to the same route. It read 4.3 miles on each display, same exact route. However, my 3rd edtition gave me a 12 minute arrival time, while my XL-S gave me a 36 minute arrival time!
At the end of my trip, my XL-S was telling me that it was going to take me 3.5 minutes to travel the last 1/2 mile! That's almost running speed.
I'm currently looking for solutions but have not come up with anything. Perhaps my XL-S simply needs to be updated with the latest maps and application software. The Tomtom home program told me that it has the latest maps - I tried to update it to the latest software but encountered an error. Will try again from a less buggy computer...
