Abstract: The introduction of a new public transport system in Santiago, Chile, in 2007 brought to us an unexpected gift: the availability of what we now call BIG DATA; massive amounts of passive data obtained from the technological devices installed to control the operation of buses and to administer the fare collection process. Santiago is not unique in this, something similar has been happening in many big cities around the world, and sooner or later, it is likely to be everywhere. Many researchers have seen this as an opportunity, and have been developing tools to obtain valuable information from the available data. However, the case of Transantiago is particularly advantageous, because since 2007 all buses are equipped with gps devices that generate a position record every 30s and a smartcard card called bip! is the only payment option available at buses, and by far the most popular in Metro, implying an overall 97% penetration rate. This presentation will include a brief description of the Transantiago public transport system, a description of what we have already obtained from the data available (public transport trips origin-destination matrices, speed profiles of buses, ...) and a discussion of what else can be obtained from this data and how it can change the way we do transport planning.
Bio: Professor Marcela Munizaga has over 20 years of experience in research and teaching on transport demand modeling, predictive models and microeconomic analysis applied to private and public transport. In the last few years she has leaded research on smartcard data and developed applications to obtain valuable information from automatically generated databases, which have been transferred to practice and used for planning purposes. During her career she has leaded six research projects, supervised over 20 theses, edited 2 books, published 14 ISI journal papers and over 40 conference proceedings papers. Professionally, has been advisor to the Chilean Minister of Transport, and participated as transport demand expert in consultancy projects. Former: President of the Chilean Transport Engineering Society, Co-Chair of the Local Organizing Committee Transport Survey Methods Conference, Chair Time Use Observatory Workshop.
