Smartphone sensing in privacy-aware environments

Steve Omohundro brings to our attention a talk at PARC on a sensing system that pays some attention to “privacy-by-design”, apparently:

This talk describes how the mobile internet is changing the face of traffic monitoring at a rapid pace. In the last five years, cellular phone technology has bypassed several attempts to construct dedicated infrastructure systems to monitor traffic. Today, GPS equipped smartphones are progressively morphing into an ubiquitous traffic monitoring system, with the potential to provide information almost everywhere in the transportation network. Traffic information systems of this type are one of the first instantiations of participatory sensing for large scale cyberphysical infrastructure systems.

Title:

Description:
This talk describes how the mobile internet is changing the face of
traffic monitoring at a rapid pace. In the last five years, cellular
phone technology has bypassed several attempts to construct dedicated
infrastructure systems to monitor traffic. Today, GPS equipped
smartphones are progressively morphing into an ubiquitous traffic
monitoring system, with the potential to provide information almost
everywhere in the transportation network. Traffic information systems
of this type are one of the first instantiations of participatory
sensing for large scale cyberphysical infrastructure systems.

However, while mobile device technology is very promising,
fundamental challenges remain to be solved to use it to its full
extent, in particular in the fields of modeling and data
assimilation. The talk will present a new system, called Mobile
Millennium, launched recently by UC Berkeley, Nokia and Navteq, in
which the driving public in Northern California can freely download
software into their GPS equiped smartphones, enabling them to view
traffic in real time and become probe vehicles themselves.

The smartphone data is collected in a privacy-by-design environment,
using spatially aware sampling. Using data assimilation, the probe
data is fused with existing sensor data, to provide real time
estimates of traffic. The data assimilation scheme relies on the
appropriate use of Ensemble Kalman Filtering on networked hyperbolic
first order partial differential equations, and the construction of
lower-semicontinuous viability solutions to Moskowitz Hamilton-Jacobi
equations.

Results from experimental deployments in California and New York will
be presented, as well as preliminary results from a pilot field
operational test in California, with already more than 4,000
downloads.

Presenter:
Alexandre Bayen received the Engineering Degree in applied
mathematics from the Ecole Polytechnique, France, in July 1998, the
M.S. degree in aeronautics and astronautics from Stanford University
in June 1999, and the Ph.D. in aeronautics and astronautics from
Stanford University in December 2003. He was a Visiting Researcher at
NASA Ames Research Center from 2000 to 2003. Between January 2004 and
December 2004, he worked as the Research Director of the Autonomous
Navigation Laboratory at the Laboratoire de Recherches Balistiques et
Aerodynamiques, (Ministere de la Defense, Vernon, France), where he
holds the rank of Major. He has been an Assistant Professor in the
Department of Civil and Environmental Engineering at UC Berkeley
since January 2005. He is the recipient of the Ballhaus Award from
Stanford University, 2004. His project Mobile Century received the
2008 Best of ITS Award for ‘Best Innovative Practice’, at the ITS
World Congress. He is the recipient of the CAREER award from the
National Science Foundation, 2009. Mobile Millennium has been
featured already on CBS, NBC, ABC, CNET, NPR, KGO, and the BBC.
