Rand McNally claims their IntelliRoute software is used by 94% of the nation's top motor carriers for their fleet routing needs. That should tell you something, a real headsup, because that's an awfully impressive figure considering that the software has only been available for about 2 years. It's so impressive as to deserve a <snort>.
They also claim that fully 91% of Fortune 500 shippers use MileMaker as their mileage standard. Again, another <snort>.
The reason these claims seem maybe a tad bit exaggerated is, according to Fortune 500 Magazine, ALK Technologies, the makers of PC Miler, control fully 80% of the world market for commercial transportation routing software, with PC Miler being used by not only more than 24,000 motor carriers, shippers and logistics companies, but also by the US government's Defense Department, General Services Administration, and the FMCSA.
As our large-picture posting friend notes, TomTom and Garmin hold the lion's share of the world GPS routing market for a reason. They are the most accurate with respect to locations and routing. Not perfect, but when all is said and done, more accurate than all the others. Most manufacturers of GPS units all us the same mapping data (NAVEQ), including Garmin, Magellan, Lowrance, as well as Web-based applications like Yahoo Maps, Bing and MapQuest. They are the mapping source for Chrysler, Mercedes Benz and most other automotive manufacturers, as well. Street and Trips uses NAVTEQ. (This is why when your Garmin can't find an address, neither will Streets & Trips or MapQuest).
TomTom primarily uses TeleAtlas, a Dutch company, with some NAVTEQ data included, while Garmin primarily uses NAVTEQ, a Chicago company, but also uses some TeleAtlas data. Garmin owns the North American market, while TomTom owns the European market, and it is generally recognized that in North America a Garmin is more accurate than a TomTom, and in Europe a TomTom is more accurate than a Garmin, though the differences are so small as to be inconsequential at this point. They are forever locked in court over each other stealing the other's routing and display algorithms. The biggest difference between the Garmin and the TomTom is the user interface, and which ever one you used first is likely to be the one you'll prefer.
NAVTEQ and TeleAtlas base their maps on government data, but the underlying map database is based on first hand observation and land mapping surveys rather than on the government supplied data (usually from county offices or their equivalent). Rand McNally uses their own maps, but is based almost entirely on government data. ALK Technologies (PC Miler) uses their own maps, as well, compiled from a variety of sources.
Because Google Maps update their maps daily, on a continual basis, their maps are probably the most accurate. But their routing leaves a lot to be desired in many cases. Basically, Google map routing is the generally most popular routing for a car. In some cases that's fine, not so much in other cases, as another route may be more efficient (especially for a truck).
But regardless of where the mapping data comes from, all of them are going to be very similar, with none of them being perfect. The differences come in routing accuracy and efficiency, and in the bells and whistles of the features. While the PC Miler standalone GPS unit features PC Miler maps and location data, the routing is performed by TravRoute CoPilot, which is vastly inferior to the routing algorithms used in the software-only PC Miler product.
I can run the same route on my Garmin, PC Miler, Streets & Trips, MapQuest and Google, and get a different routing for each. Depending on the settings, faster, shorter, car, truck, practical, HAZMAT, I can get multiple routings for each. Somewhere in that mess is the best route, so it's a good idea to have several mapping and routing tools at your disposal. I also have a Droid with Google Maps, Google Navigator, and Google Earth loaded on it, which certainly comes in handy at times.
Many standalone GPS units now factor real-time traffic information into the routing, and again while not perfect, it's good to have. Some, like the new Garmin Nuvi units, actually keep track of and learn traffic and travel time trends for regular destinations based on time of day and other factors. Many new units have lane assist and will accept voice commands.
But the bottom line is still mapping and location accuracy, and accurate and efficient routing. Once you go beyond the standards of a Garmin or a TomTom, it's a crap shoot. People will say they've got this or that GPS and it's not a Garmin or a TomTom, and they just luv it. These are people who, generally speaking, have never used a Garmin or a TomTom. Yeah, yeah, yeah, I know, there are exceptions to everything, but again, there's a reason these two companies dominate the GPS market, and it's not because of marketing.
GPS units specifically designed for trucking are intriguing, but they are still not there yet, not where they should be. Most, like the Rand McNally units, have great trucker information, but fall short on proper truck routes. The Garmin truck unit went too far with its truck routing and gives too much weight to the STAA truck routes, when they'd have been better off using the same routing algorithms found in their other units. They're working on it. The Rand McNally units are great, except they are the truck map experts, not routing experts, so they have a long way to go, too. The PC Miler unit, well, they took what could have been an awesome product and ruined with a second rate routing program, so try and forget about that one completely. It's pretty bad.
