Extract Google Traffic Layer

Yeah I would like to extract the data (attributes and geometry).

 

I didn't thought about the possibility that the traffic layer would be a basemap though. I was sure that it was a dynamic vector layer, overlapping the default basemap. If so, I can give up my project...

Thanks anyway!

I just found that documentation about Directions API : Google Direction API

With the HTTPCaller, I'm going to be able to calculate the time between point A and point B!

Thank you guys!! :D

How is the Direction API an answer to your question, @philippeb? That doesn't really tell you anything about the (current) traffic situation, does it?

 

For what it's worth, I once made a "ripper" for Google Traffic maps (all within legal bounds, by the way ;)). First tried to contact Google if it was possible to access this data (and even pay for it) but never got a proper answer, so I built something myself.

 

Basically used an HTML page with custom CSS styling for the Google Traffic Layer and background map, so I would get a "high-contrast" traffic map without too much background noise. I ran this HTML page on localhost and then wrote a script (outside FME) that would render this page at a certain pixel size. The resulting image basically was like a map tile. You needed to specify the latlon bounds and level of detail for the script and it would generate all map tiles for that area within a couple of minutes. The tiles were processed in FME and the traffic congestion values (green - orange - red etc.) were assigned to actual vector road segments along with a timestamp. Along with some average hourly traffic intensity data we had, we could give a rough estimate of the amount of cars that were actually passing by on a road segment at a certain time.
