  • Unclogging Traffic Congestion
    May 29, 2009 - Smart Planet

    Imagine a commute without traffic congestion. Alex Bayen is currently working on the Mobile Millennium project, a traffic information system that uses GPS inside phones to gather traffic information, process it, and then broadcast it back in real-time, so people can have instantaneous traffic updates.

  • Mobile Phones as Sensors for Enhancing Lifestyles
    March 4, 2009 - Nokia Distinguished Lecture Series

    Using mobile phones to access information from the digital world of the Internet is becoming common, and many people are also using mobile phones to explicitly publish information to the Internet. But today's phones also have sensors that enable them to observe the physical world around them and potentially share this information, either autonomously or semi-autonomously. This provides a huge potential to have communities of users collect information about the physical world and fundamentally change our collective awareness. The physical world contains more sensory data than we can possibly comprehend... so which data is important? How muc do we need? And most importantly, how do we ensure that the phone maintains this trust by diligently protecting the privacy and safety of its use?

  • Using GPS Mobile Phones as Traffic Sensors
    April 1, 2008 - Mobile Century Public Information

    UC Berkeley and Nokia researchers used GPS-enabled cell phones to test a technology that could soon transform the way drivers navigate through traffic. In the unprecedented Cal-trans funded field experiment, transportation researchers used GPS-enabled mobile phones to monitor real-time traffic flow while preserving the privacy of the phones' users.

  • Using GPS Mobile Phones as Traffic Sensors
    February 8, 2008 - Mobile Century Project Overview

    The convergence of communication and multi-media platforms has enabled a key capability: mobility tracking via GPS. Business plans of most major cellular phone manufacturers such as Nokia include embedding GPS in all manufactured cell phones within less than 18 months. Thus, a high penetration rate of GPS-equipped travelers on freeways is expected in the near future. This has major implications for the traffic engineering community, which currently monitors traffic using mostly fixed sensors such as cameras and loop detectors, or location specific sensors such as FasTrak or EZ-pass transponders.

    This seminar will present a prototype of location-based service: real-time traffic monitoring using cellular phones only. The seminar will take place while the field experiment "Using GPS Mobile Phones as Traffic Sensors" is in progress: 100 vehicles carrying a GPS-equipped Nokia N95 cell phone will drive along a 10-mile stretch of I-880 between Hayward and Fremont, California.
