Slashdot is discussing a story on improving GPS navigation systems with traffic flow data. Their summary: "According to a story in Technology Review, some GPS companies are factoring in traffic flow and time of day. From the article: 'Tele Atlas, a Boston-based company that provides digital maps and navigational content, has integrated new trafficking software into its map database so that drivers can find the most optimal route based on speed rather than distance — for any stretch of road at any hour of any day of the week."

RFID and GPS to Eliminate Traffic Jams?
[+]
Very Spatial links to a Technology Review article subtitled new research shows that making drivers pay higher tolls at peak times and tracking their location with RFID or GPS technology can eliminate traffic jams. From the article: "Kockelman says such simple market mechanisms can solve traffic problems without requiring the construction of new roadways. "Meeting travel needs is largely a function of sending appropriate pricing signals to travelers," she says. "We can allow them to make their own decisions, rather than having to expand capacity in our nation's already extensive roadway networks.""
How Online Maps Update Their Data After Major Road Closures
[+]
Several blogs discussed the re-routing of webmapping directions that happened after a freeway connector collapsed. It started with the Brain Off blog, Mapping Hacks and All Points Blog provide comments. The Map Room shares additional links (yes, I did copy TMR's entry title). From the article: "Some services reflected the altered landscape right away, some needed a few days, and some still don't show that anything has changed.
Even some of the Web sites that show alternative routes around the melted MacArthur Maze don't give the same directions that Caltrans and the city of Oakland have asked people to take. [...] Satellite services like GPS provider Magellan don't update their maps, but customers who pay extra for traffic updates would see that the road is closed. Drivers can also tell their devices that they need an alternative route."

Karl, a new contributor, shares this story with us: "Until today's announcement from Mercedes Benz, it seemed that using internet connectivity to update route on a navigation system in the car was a distinguishing feature of the soon-to-appear Dash Express from Dash Navigation. "The Search & Send feature allows drivers to plot destinations, addresses and points of interest through the highly popular map sections of the Google or Yahoo! Maps websites and then simply click on a newly introduced "Send to Car" icon. The information is then sent directly to the vehicle's GPS navigation unit." Link to the article in Telematics Journal here."
