Is There Linux Trip-Planning Software?

Spiral Man writes: "There has been a lot of talk lately about Linux on handheld and embeded device. One interest of particular interest to me is in-dash computers for cars. Probably the most important app for one of these (aside from the CD player) would be a navigation and trip planing package such as DeLorme's Street Atlas, and Microsoft's Streets USA. My question is: Are there any apps, or even plans to write apps like this for Linux. Preferably these would use a commercial, or at least well updated, street database, and would have to be able to track you current location with a GPS." Especially considering the coming flood of GNU/Linux-based handhelds and dashboard computers, this question will be one of the toughies for folks who want to use Free software wherever possible, but who also want the capabilities in applications like Streets USA. Are there any competitors out there in the Free world?

This was added to woody just yesterday - looks very decent. It doesn't do street-to-street routing, but looks pretty good for city-to-city stuff. Has CLI, newt, and gtk interfaces. Grab the source here.

The problem is, Yahoo! Maps sucks

At first glance, it looks good. But start comparing some of its routes to other mapping programs (Rand McNally, for example) and you'll see Yahoo! tends to miss a lot of details and makes you change roads unneccessarily. I've done better than both Yahoo! and PC-based programs just looking at a plain old paper map. A relatively small nitpick about Yahoo! - it figures your time based on a 55MPH average. If you're driving long highway miles, you're going to average a lot better than that.

I just checked 2 routes on Yahoo! Maps, one trip that I've personally driven completely and another that I've done about halfway. One was from my home to Arlington, VA. Where's it take you? Across most of the major highways in southern Pennsylvania, then right down the Baltimore-DC corridor. And then (get this) right through DC and down Pennsylvania Avenue! Get comfy - you'll be sitting still for a while there. I plotted my own route which was faster, shorter, and had much less traffic.

The second route was Boston to Seattle. Still a lot of excess road-switching, and oddly, it didn't route through Ontario between Buffalo, NY and Detroit, MI, which is my preferred route. You miss a number of cities going that way. Also, it keeps you off of I-90 for the majority of the trip, which just about the most direct route.

I'll be sticking with paper maps for a while. If you've got someone riding with you, let them read. And whether you're solo or driving with someone, a stop every few hours along the way to get out and stretch your legs is good for you anyway.

Yes this is particularly annoying in the west.

The "mapping" programs often choose the state routes because the distances are a bit shorter, but the highways out here often have speed limits of 75mph (compared to 55 or 65 on the state routes).

Also the point about local traffic is well taken, it would be really cool if these planners took into account the time of day you left, the local traffic conditions, and planned alternate routes if you hit certain waypoints in your trip (near high traffic areas) at bad times (ie DC down Pennsylvania or rush hour route 128) where its almost always quicker to go around the traffic even with the lower speed limits and stop lights. Of course this would require a much better database, but would be significantly more useful. I'm surprised someone isn't working/charging for this already (or maybe they are, NDA interviews anyone ;) ).

From the Netpliance I-Opener hacking board: Great GPS implementation has both Win and Linux stuff in it.

This may be more to the point: GPS for Linux on the same board. Mentions Mayko, which is what I will be trying on my vehicle-mounted I-Opener, but on FreeBSD. Not exactly trip planning software, but covers the navigation portion of your question.

Note that the GNOME project "gmap" will compress and render this data.

Where, TIGER Line Data, but first look at Bruce's free software page. The map data is 2.6GBytes at 90% compression. Download the manual first, then and only if you are really going to do mapping software get the data. Better yet only get the data for one state and work with it first. I've been working with a small subset and using a 30GByte scratch space that feels a bit tight. My goal is to reduce it to CD-ROM size but still have a useable data set. Unfortunately I stalled out awhile back on it. I do have a mostly correct set of DB file table and appendix data entered. The errors are easy to spot, I just forgot where they were so the files aren't corrected. Once my life becomes stable again I plan on working on the size reduction again. Disk space was one of the factors that stalled me out.

Trip Planning?

[FPhlyer]

How hard can it be to plan a trip? I just kind of get on the road and head toward my destination. I can get to practically any location in the Continental US in 32hours or less. Sometimes I do use a road atlas (hard copy). I find that this method is more efficient than any of the software packages that I have seen or used.
