All Points Blog discuss a new service by Inrix which provide predictive and real-time traffic service for Windows Mobile devices. This site indicates which information is used: "Inrix acquires real-time and historical sensor data from hundreds of public and private sources including anonymous, real-time GPS probe data from more than 625,000 commercial fleet, delivery and taxi vehicles; toll tag data; and occupancy and speed measurements from Department of Transportation sensor networks. Additionally, the Inrix Smart Dust Network aggregates real-time incidents and hundreds of market-specific criteria that affect traffic – such as construction and road closures, sporting and entertainment events, school schedules and weather forecasts." See the numerous related stories below.

RFID Solution to Rush Hour Headaches
[+]
All Points Blog links to a MSN/CNET article about a RFID solution to rush hour headaches in Stockholm, Sweden. From the article: "In Stockholm, car owners are being encouraged to glue a RFID (radio frequency identification) transponder onto the inside of the windshield. When drivers enter or leave the city, electronic register stations along the road pick up radio signals from the transponder, and a central computer system charges the car owner's bank account." This reminds me of this related previous story about British drviers mad at Galileo.
Sensing Traffic From Vehicles
[+]
This 7.5th Floor story points to a Mercury News article on Inrix, a company that will provide traffic information from pooling GPS data from vehicles. From the article: "Inrix, a Microsoft spin-off, will deliver traffic information gathered from more than a half-million ``sentinel'' commercial vehicles, equipped with GPS locators, to improve the speed and accuracy of its traffic-flow information, company representatives said last week."
Live Traffic on Mobile Phones from Google
[+]
Slashdot discuss a Reuters short news on Google offers live traffic maps on cell phones. The slashdot summary: "Reuters is covering the newest offering from Google: real-time traffic mapping on your cell phone. Now you can check how the traffic is ahead of you, of course as long as you don't cause the traffic incident yourself by checking the local issues on your cell phone while driving. Point your cell phone browser to http://google.com/gmm to get your local traffic maps if you live within one of the 30 U.S. cities where this is available."
Tracking Your Cell Phone for Traffic Reports
[+]
Slashdot links and discuss a short LiveScience article where cell phones are tracked to generate traffic reports. The slashdot summary: " IntelliOne Technologies has just launched a real-world test of Need4Speed, a real-time traffic-monitoring system that tracks drivers' cell phones. From their website: 'Unlike any other solution available today, the IntelliOne Roadway Speed Measurement System produces live roadway speeds for all highways and surface streets where mobile phone coverage exists, accurate to within three miles per hour.' Of course, any compulsory phone-tracking system raises privacy concerns. According to an article on LiveScience, 'the personal identification data of users will be stripped from cell phone signals before they are processed by IntelliOne's software.' The cell phone companies have this data, but IntelliOne says they won't be keeping their copy."
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.""
BMW Releases First Dynamic Traffic System in US
[+]
Very Spatial links to a Autoblog mini-announcement of BMW release of a dynamic traffic system for the US. From the mini-article: "BMW announced today it would be equipping select 2007 models with Real Time Traffic Information. Provided by Clear Channel's Total Traffic Network to 44 major American cities [...] What's more, it's free for four years with the cost of the navigation system. [...] BMW also claims the system will be the first sold in the U.S. that offers dynamic rerouting on the navigation system."
Google Maps Adds Traffic Conditions for some U.S. Cities
[+]
The Map Room links to the official Google blog which informs us Google just added traffic conditions in Google Maps for 30 U.S. cities. From the blog: "For more than 30 major U.S. cities, you can now see up-to-date traffic conditions to help you plan your schedule and route. If you're in San Francisco, New York , Chicago, Dallas, or any of the other cities we now include, just click on the traffic button to show current traffic speeds directly on the map. If your route shows red, you're looking at a stop-and-go commute; yellow, you could be a little late for dinner; green, you've got smooth sailing." All Points Blog discuss Google's source data.
Peer to Peer Networking for Road Traffic
[+]
Slashdot discuss the advent of peer to peer networking for road traffic. Their summary: "The BBC is reporting on some German research to allow the exchange of information between road vehicles about travel conditions using peer to peer networking (I assume some sort of mesh). Cars or bikes experiencing problems would pass data that would ripple down the chain of vehicles behind them. 'For example, cars could spot oil on the road by combining temperature readings with wheel traction information. A wheel slipping on the road even though the temperature was not low enough for frost or ice would suggest oil or another slippery substance was present. Once a car detected this sort of danger, information about it would be generated and passed down the line of vehicles approaching the patch of oil.'"
Technology: New GPS Navigator Using 'Wisdom of the Crowds'
[+]
Slashdot discuss a new GPS navigation system which relies on 'wisdom of the crowds'. Their summary explains it more clearly: "The New York Times is running an article on Dash Express, a new navigation system for automobiles that not only receives GPS location data, but broadcasts information about its travels. Information is passed back to Dash over a cellular data network, where it is shared with other users to let them know if there are slowdowns or traffic jams on the road ahead. The real benefit of the system isn't apparent until enough units are collecting data in a given area - so Dash distributed over 2,000 prototype units to test drivers in 25 large cities." All Points Blog also links to a Wired article on Dash. In related stories below, I included many previous stories which aim at real-time traffic info from Nav Systems.
GPS Cellphones to Monitor Highway Traffic
[+]
Slashdot discuss an experiment using GPS-enabled cellphones to monitor traffic.
Their summary: "On February 8, 2008, about 100 UC Berkeley students will participate in the Mobile Century experiment, using GPS mobile phones as traffic sensors. During the whole day, these students carrying the GPS-equipped Nokia N95 will drive along a 10-mile stretch of I-880 between Hayward and Fremont, California. 'The phones will store the vehicles' speed and position information every 3 seconds. These measurements will be sent wirelessly to a server for real-time processing.' As more and more cellphones are GPS-equipped, the traffic engineering community, which currently monitors traffic using mostly fixed sensors such as cameras and loop detectors, is tempted to use our phones to get real-time information about traffic." Some related stories copied below, including a story on mandatory cellphone tracking in the U.S.
