Navteq Traffic Improvements

 

If you look at the Navteq website, it looks like Navteq has updated its traffic database to include flow speeds for surface roads in addition to just interstates. This must be a relatively recent update, because last time I used this website, only interstate flow speeds were available. I hope these new flow speeds are transmitted to our nuvis so that if there's a traffic jam on the interstate, the GPS will know whether the surrounding surface streets are just as congested. Check it out for yourself and see it for yourself: http://www.navteq.com/
You have to zoom in a little to see the flow speeds on the surface streets.

Cool! Maybe Navteq will start catching up to Clear Channel.

On the Navteq site, Toronto

On the Navteq site, Toronto (where I live) has surface road data as well, however, I've only seen data for the highways come across to my device

I hope this data gets transmitted as well. I don't know whether the FM stream can handle the amount of data though.

All green in Albuquerque currently

A little past noon on May 3, the Navteq view of Albuquerque colors most of the "1-mile" major streets, plus a bit more downtown. Every colored pixel is currently green. That makes me wonder whether the system is actually up and running here yet.

Google Maps has had a somewhat similar representation available here for some months (maybe even years). At the same moment Navteq colors everything green GMaps has quite a bit of yellow and some red.

I need to look again at morning and afternoon rush hour to get a better idea of current utility.

I do think the idea of crowd-sourcing real-time traffic flow data by using cell-phone tracking of a large number of cooperating phones is the only detection scheme on offer which has some promise of providing useful fine-grained traffic data at reasonable cost. Does anyone here know what the source of the Navteq data is? I have the impression that Google is using something like the scheme I described, perhaps largely from Android cell phones.

Where Navteq acquires their data from is a little different for each metropoitan area according to their website traffic.com. When you type in traffic.com select which city you live nearest. Then when the live traffic comes up, on the right hand side of the screen toward's the bottom you'll see "More (City's name) area traffic sources." Once you click on that, all of the sources that Navteq uses are listed with links. Here's an example: http://bhelp.traffic.com/Resources_for_neworleans
You can find this information for whichever city you want. Even if your city isn't directly listed, you can get an idea by looking at other areas' sources. Just go the Traffic.com's homepage to view all the metropolitan areas that are exclusively covered.
