ADMS (Archived Data Management System) archives real-time feeds from several different systems (freeways, arterials, and transit) from regional agencies, and provides data on traffic flows, incidents, and transit service. ADMS is a rich resource, not only for systems operations, management and planning, but also for analyzing impacts of system changes, from new infrastructure investments to fuel price variations. Access to this comprehensive historical archive of real-time multimodal system performance data has provided a unique opportunity to demonstrate how “big data” can be used for transportation planning and
policy analysis. With funding by Metro, we use ADMS to evaluate the impacts of a major light rail investment in Los Angeles (the Expo Line) on corridor-level multimodal transportation system performance, comparing corridor-level system performance before and after opening of the rail line. Our findings reveal a significant positive impact on transit patronage, largely due to the existence of latent demand for high quality transit travel.

Deen Distinguished Lectureship Award (2007), and the Transportation Research Forum Outstanding Researcher award (2012). She was recently appointed to the National Freight Advisory Committee.
Sandip Chakrabarti is a Ph.D. candidate in urban planning at the USC Sol Price School of Public Policy and research assistant at the METRANS Transportation Research Center. His research focuses on the relationships between land use and transportation, the influence of value of time and reliability on travel behavior, and transportation policy analysis. Sandip completed his Master of City Planning degree from the Indian Institute of Technology (IIT) Kharagpur, and worked as an urban planning consultant in New Delhi, India, before joining the Price School. Sandip has an undergraduate degree in Architecture, and is keenly interested in urban design and development.
