Google has just released an update to Android’s Maps Navigation which makes it possible to re-route to avoid traffic congestion, enabling users to get to where they’re going with less hassle. The free Google Maps Application received the update in the last few days, making it possible for Android users to avoid traffic jams in America and much of Europe.

Google Navigation used to calculate the shortest route and alternate routes, by allowing the user to choose side roads instead of highways. The inclusion of traffic data will allow Google Navigation to choose alternate routes around traffic problems and to help the user to more accurately decide which route will be fastest overall.

Traffic data is gathered in real time and collated to anticipate future traffic problems. Google claims it will always try to find you the fastest route to wherever you’re going, in order to save you time and fuel.

The new functionality is automatically included, so simply start the Navigation application as normal or enter navigation via the Google Maps application. Set your destination and Google will try to find you the best route.

It’s also possible to add traffic information to Google Maps via a layer (not to be confused with Layars). To do this, click on the layers button in the top right corner and choose traffic. This will overlay traffic data onto your maps whenever you’re browsing Google Maps “” not just when you’re using it for navigation.

can navigation runs without wifi / 3g? can it runs only on gps with downloaded map? is there any android gps program that can runs with google map (without internet connection)?

Google Maps can run without 3G, but you need the maps to make any sense of it. If you pre-fetch the maps while you have internet access, you can keep them cached and check them en route.

Navigation requires the use the GPS, which is possible without Wi-fi or 3G service. But, to get the up-to-date traffic information you’d need 3G access. In theory though, if you weren’t going far, you could run Navigation before leaving your internet access and check the map details. All that information should be cached and the GPS would still be able to track your position. It’s something worth experimenting with!



how is traffic data gathered and sent to end users?

They’re collecting data over time as well as immediate data, so they can predict as well as report. I guess the bulk of their information comes from satellite data and news reports.

As for how the users get the information, it’s all shown in the Google Maps application. Whenever you look at any area of the map you have the option to view the traffic data layer (see instructions in the post ) or by using the Google Navigation application. It will automatically offer you the choice to avoid known traffic problems.
