*Big Data to Tackle Urban Challenges*

*Marta GonzalezMassachusetts Institute of **Technology*

Urban mobility models are important in a wide range of application areas.
Current mainstream models require socio-demographic information from costly
manual surveys, which are in small sample sizes and updated in low
frequency. In this study, we propose a novel individual mobility modeling
framework, TimeGeo, that extracts all required features from ubiquitous,
passive, and sparse digital traces in the information age. Combining
demographic data, road network information and billions of mobile phone
records, we infer travel demand profiles and estimate travel times across
five different cities. We demonstrate that the percentage of time lost in
congestion is a function of the proportion of vehicular travel demand to
road infrastructure capacity, and is closely tied to spatial density and
selfish choices of drivers. In this context we explore the feasibility of
smart routing applications.

*Marta C. Gonzalez*
*Professor of Civil and Environmental Engineering; Director, Human Mobility
and Networks Lab*

*Marta Gonzalez *left Venezuela where she grew up to pursue a PhD in
Physics in the University of Stuttgart, as a selected fellow of the DAAD
the German agency for students exchange. Next, moved to the U.S. to do a
postdoc in the Barabasi Lab.  She is currently Associate Professor of Civil
and Environmental Engineering at MIT, where she has worked since 2009. With
support from several companies, cities and foundations from around the
world, her research team develops computational models to analyze digital
traces of device-mediated interaction to explore the use of urban
infrastructures.
Recent research uses billions of mobile phone records to understand the
emergence of traffic gridlocks and the integration of electric vehicles in
the power  grid,  records of smart meter data to compare policy of
photovoltaics, and credit card transactions to identify spending urban
habits. Her research has been published in leading journals, including
Science, PNAS, Nature and Physical Review Letters.
