Traffic information missing

[JohnyQ]

There's traffic information available in many cities showed on maps.google.com which doesn't display trough the API.

I'm trying to display Buenos Aire's traffic information in a website but the map the same map that shows green and red lines in USA shows nothing in Buenos Aires and many cities that do contain information.

Does anyone know if there's access to the information missing or Google just rolls out new areas as they see fit?

Is there a way to egt an estimated date when that information will be available?

Same happens in Europe. For example on maps.google.com you see France's traffic:

but in the overlay got through the API, France is empty:

Hi Johny,

The traffic layer is not available in some locations through the API due to licensing restrictions.

not sure - whether legally - but it can be 

var traffic = new google.maps.ImageMapType({

    getTileUrl: function(coord, zoom) {

      return "http://mt3.google.com/mapstt?" +

      "zoom=" + zoom + "&x=" + coord.x + "&y=" + coord.y + "&client=google";

   },

   tileSize: new google.maps.Size(256, 256),

   isPng: true

  });

map.overlayMapTypes.insertAt(0, traffic);

Hi Chris and thank you for your quick answer.

I posted this because I thought it wan´t a technical issue (if some traffic shows, if some other doesn't it must be something else) but I don´t quit get it:

I read in the official Google Blog that traffic information goes from devices running a Google Map App to Google servers, Google process it to determine traffic conditions and then with that generate the traffic layer.

From what I understand no third party is envolved in the whole process (from making the app that collects the user's GPS speed to hosting the traffic tiles). Even if I'm wrong there shouldn't be any third party involved because of the serious privacy issues described in the blog post itself.

So... if no 3rd party is involved in the whole Traffic thing, why is there a licensing issue? 

Is there some rivalry between the Traffic team and the API team inside Google? :P

Seriously, how can it be a licensing issue inside Google?

I would like to know the reason but even if I don't understand it I trust that if Google is not showing it, it's because they really can't not because they don't fancy to do so.

So, is there any solution for this? Will this information be available in the future? API Premiere has the same limitation?

Yury,

These tiles are not part of a Google API, and as such, use of them constitutes a violation of the ToS.

Johny,

Traffic data comes from a number of providers. In some areas, this license is not compatible with serving such data through the Maps API.

Cheers

Chris,

but the example is taken from here

Sorry about that. The documentation is out of date. I'll update it shortly.
