GPSs * Holland - The Road Less Stupid
Dutch firm Tele Atlas builds detailed geographic databases that are used by navigation devices and Web sites to provide information to drivers
Holland -Forbes (New York,NY,USA), by JonBruner -10 Oct 2008: -- ... Data are collected by vans equipped with a global positioning system antenna, a laser measuring system, and digital cameras that ensure accuracy to within six inches. Data is fed into hard drives located in the back of the vans and then analyzed to identify address numbers and road signs and to reconcile changes... As sales of navigation devices slow, in part due to the proliferation of GPS-enabled smartphones, navigation device and mobile phone makers are looking to next-generation services to draw customers... Data currently collected but not utilized by navigation devices includes information on elevation to calculate roadway grades... The next-generation of cars and trucks will have back-seat drivers that will allow vehicles to anticipate an upward tilt in the road and downshift automatically at the right moment, thus increasing fuel efficiency. Other future technologies enabled by the data collected by service providers like Tele Atlas include lane departure warnings for drowsy drivers and adaptive headlights that know when corners are coming...
* USA - CarTel Personalizes Commutes by Using WiFi to Network Cars
Mass,USA -The MIT News, by Elizabeth A. Thomson -10 Aug 2008: -- The Massachusetts Institute of Technology's (MIT's) CarTel project uses automobiles to monitor the surrounding environment by sending data from an onboard computer to a Web server where data can be visualized and browsed. The cars use pre-existing Wi-Fi networks they encounter while on a trip. The resulting data, which can be accessed from the Web or on a cell phone, helps drivers track conditions specific to their cars and provides historical and real-time traffic conditions at different times of the day using combined data from all CarTel participants... MIT professor Hari Balakrishnan says the goal is to make the data behind CarTel available to the public and to help travelers plan and organize their trips. The current system, which was deployed in 50 Boston-area cars in January, monitors traffic by recording each vehicle's speed at different points during a round trip. MIT professor Samuel Madden says CarTel understands where traffic delays are and recommends alternative routes to avoid them. To make CarTel possible, researchers developed QuickWiFi, technology that can connect to a Wi-Fi network in 360 milliseconds. Researchers also had to focus on managing the huge amounts of data the system gathers. Depending on the sensors in use, CarTel can receive more than 600 data points per second, so the team developed two generations of software to synthesize all the data for use, including a series of new algorithms for traffic-aware routing...
