In planning part of my upcoming trip (Sell, house, sell!), I checked four online maps to see how long it would take to get from my location in NC to Sioux City. The results: Google 19:31, Mapquest 18:51, Yahoo 18:19, and Bing 17:11.

So . . . allow for Google and hope for Bing? Anyone know which map is usually closest?

I did find that Google has me going an average speed of only 61 mph. Maybe Google figures in stops and Bing doesn't?

Why rely on someone else's idea? Do it yourself. You know how you drive and how long you stop better than any of those silly computer programs.

It's pretty easy to do: Mileage divided by expected average speed yields trip time.

I know Google Map Logic adds in time for Red Lights, Left Turns, Stop Signs,
It factors in 'Going thru town' at a slower speed then the posted speed limit.

Those times are for actual road time only, and you know how fast you drive.

Assume it is going to be on interstates, so you can average about 65. Add some time for gas stops, and you know better than Google does how long it takes you to pee. Add some time for food stops, and you know better than Google how long it takes you to demolish a Whopper or stuff yourself at a Golden Corral.

I just googled Asheville to Sioux City, and got 1127 miles, and 18:26 driving time. That's 61 mph average. So it obviously does not count stops for gas or food. It should be easy to average 61, since it is interstate all the way. Just add whatever time you need to gas up and food up,

If Bing thinks you can to it two hours faster, that's an average speed of 69. How comfortable are you trying to do that?

My advice is to forget about all high tech devices (like internet mapping and gps), get in your car, follow big green signs with arrows to Knoxville, then Nashville, St. Louis, Kansas City, Omaha and Sioux City. Give yourself two days, and stop at a motel when you get tired and eat when you get hungry and gas up when the needle points near E. Watch the speed limit, get off the road to rest a few minutes every couple of hours, and look way down the road.

Well, yes, I've done the math. I'm assuming Google and the others have more information about the areas, and that they are factoring in that information. I just wondered which does it the best.

Why is it important? I'm planning a trip that's almost 2900 miles, and I need to plan my stops ahead of time because I will be traveling with three cats. Except for very quick gas and restroom stops, it will be hotel door to hotel door. If it were just me, I could stop when I wanted. So if Bing is right, I might go farther than Sioiux City in the first two days. If Google is right, I might not even want to go as far as Sioux City.

For now I'll assume the answer is somewhere in the middle.

You're worrying about an hour difference? Must be a slow day where you're at!

No map site will give you absolute travel times. Each of us drives differently. Relax and enjoy the journey.

Two hours and 20 minutes. Over an hour/day. Driving with cats, which means no real breaks. But don't worry, I'm not worried - just planning.

And curious. Maybe I should have left out my own story and just asked about the maps. No one else is even curious about the 2:20 minute difference between Bing and Google?

I'm sure it's in the formulae somewhere. One may use actual posted speed limits, one may do it by road type and not take local differences in account. Eg. all interstates are 65, secondary 55, tertiary 35.

It's a general guide anyways. If you think about it, it's a 5% variance. That's not a whole lot.

I usually print a map and highlight my route. Next I figure out how many miles is my trip and how fast I have to be there. Then I start to chop it in pieces: but ... its up to your personal style how fast you will drive and how often you need to stop. With a help of a map, you can figure out where you want to make your stops - in a small village, in a town, in a rest area? Do you take your own food or want to stop& eat? The next question would be where? Pick a town and get a map of it, so you would know where the food is. Are you in a hurry? Or you don't mind to stop for an hour or more to visit an interesting place? If your route include passing through bigger cities, you must count with delays ( traffic, construction). Decide where you want to overnight, find a hotel, call for room availability and ask if they accept pets. You don't want to drive somewhere in dark and start to look for a place when you are tired and cranky.
If you have GPS you can program your route and get live info about traffic conditions, and the length of your trips between stops.

Good luck and have a safe trip!!

Google makes Google Earth. Just because of that I trust Google the most.
