Yahoo! Maps to Support Realtime Traffic

squidfrog writes "Yahoo is set to support realtime traffic overlays for its existing Yahoo! Maps program. 'Yahoo's dynamic maps draw on real-time traffic information from metropolitan transportation departments and private providers, including embedded road sensors, traffic cameras, police scanners, and traffic helicopters. Yahoo declined to identify the exact sources of its traffic data... Roadways are colored green, yellow and red, to highlight the normal movement of traffic, minor delays or severe road congestion. A user can hover over a stretch of road to view details of impediments.'"

Thanks to UIC, Chicago has this too.

one possible source for data

[Fratz]

Traffic.com also posts realtime traffic flow information, and they say they get their data from these sources.

Actually, when you view the map, it displays exactly where its getting its information from. Whether it pays for it or not is still to be determined.

In regards to traffic cameras being a waste of money, perhaps. But even if they do not currently have any ways to reduce traffic, a simple easy way of knowing where traffic is bad and being able to redirect accordingly should be of some help. Additionally, when the technology is developed to dynamically, intellegently alter traffic patterns, then the infrastructure will be in place to make it possible.

Add the Twin Cities to the list...

They also have traffic cameras, which I find much more useful.

TMC in Europe... nice if this could be here...

[cytoman]

Apparently, in Europe, there is something called TMC which is a standard for all of Europe. The GPS software there can make use of this to give you additional information on traffic. Below is an excerpt of a review on OnCourse Navigator from http://www.pocketgpsworld.com:

TMC

Traffic Message Channel is a pretty successful system in some European countries that transmits current traffic conditions via the RDS (radio data system) components of standard FM radio station broadcasting. Provided with a special GPS receiver (which basically includes a FM radio) users in Europe can let Navigon adjust it's routing decisions based on the incoming TMC messages. In the US the picture is very different. Every metropole has its own traffic messaging system, they are all incompatible, and most of them are not free services anyhow. As a result the OnCourse Navigator program has left out the TMC functionality. If you come over from Europe and use your MN|4 with the maps of OnCourse Navigator then keep in mind that TMC is of no use here.

Someone want to explain to me how a camera reduces traffic? Considering they have no dynamic ways to alter traffic patterns, seems like a royal fucking waste of money and something bound to be abused.

Obviously cameras don't reduce the gross flow of traffic, but they might help ensure that the traffic keeps flowing as smoothly as possible - for instance dispatching police, tow trucks, or other emergency crews where necessary. It can also be used for road condition analysis for display on information boards that might lead some to take alternate routes (just as the local media usually monitors them as well to gauge traffic patterns in real time).
