Google Maps Now Does Interactive Re-Routing 188

    i noticed this today and its a good idea though the most complaints i hear from my customers (uk) when i point out how Google maps works and how to use it is the accuracy of driving directions, and so they tell me after using that they still prefer to use Mapquest/AA even though their visualisation of mapping is inferior to Google's, fancy draggable routes mean nothing if the directions are wrong or inadequate for route navigation and so i cant really argue with them because its true (in my/customers experience)
    while calculating directions is a very complex task (1 way systems, roundabouts, roads closed etc) i think this is a challenge that Google could excel at

      That's interesting. I don't know about the rest of the world, but in the US Navteq provides the data for both Google Maps and Mapquest (and Yahoo! Maps as well, I believe). So you would think the directions would be no less accurate. On the other hand, I have definitely noticed the different services do often recommend different routes from the others, despite all being run by Navteq.

      Anyone else know more about this?

          My experience with my Garmin GPS is that you cannot rely on precise locations - especially of addresses, though also offramps at times. The best strategy I've found is to get the basic route (such as "now head east on US 89") from the GPS, but then use the signs on the road to do that, rather than looking too closely at the GPS.

        The map data has nothing to do with the routes. All Navteq sells to Google and Mapquest is a massive amount of vector-data that maps streets in geo-spatial coordinates. It is up to Google and Mapquest to determine the shortest path between any two points using this data.

        It is more difficult than it sounds. Discovering the shortest path in a weighted map is a simple, well known algorithm that any third year computer science major would have studied. The problem is in the weighting. Things such as speed limits, number of traffic lights, road conditions, speed limits of intersecting roads, ourly traffic patterns - all of these affect the amount of time one route takes over another.

        Aside from the fact that it is impossible to be up-to-date with this data on a constant basis, some of it changes based on the time of day of your planned trip. For example your morning "shortcut" to work may not be any faster on the weekend when the main route is not as congested.

        I think in general, all the mapping sites to a remarkable job given the data they have access to. It is highly unlikely ny one site is "more accurate" than the other picking routes all of the time. What is probably happening is the place where you are going has some factors that have changed recently, or have not been acounted for, in one site vs. the other. You would for certain be able to find counter-examples that make the other site look better at other places in the country.
    • This is a feature that I've wanted for awhile. This is especially handy when trying to give directions to people. Automated routes sometimes aren't the best. A few tweaks and you could have directions that follow a route that you know is better or easier to follow. Avoid construction, bad intersections, traffic jams that will probably happen, but haven't yet.

      Thank you.

They could have added the concept of beltways, or it could simply be that the beltway is a single road as opposed to a straight local street drive.

      Well, if you're a AAA member you can get this now. For example, I just did a 1,300 mile drive and used AAA's website to get the directions. You set the starting location and the destination and then you can add things like construction information, restaurants, hotels, gas stations, etc. You can add multiple stops, force it to take certain routes, etc. It ends up with an overview similar to what MapQuest and Google Maps do, but then it also gives around 30 pages with detailed maps of every intersection and major area, alternatives, etc. It's really nice.

      This is why I don't bother with Google Maps or Mapquest any more. They're very primitive by comparison. Though, I do use Google Maps when I'm familiar with an area and am just not sure exactly where something is.

      It's a little more complicated than the traditional salesman problem because these graphs are weighted and directed. Even then there are still good algorithms to calculate such routes. Most algorithms are "fast", but not 100ms or 200ms fast. For the speed and scale that Google does this at, it's pretty damn impressive.
