Big Data for ITS: experiences from the field and academia

It has now been 18 years, since John Mashey[1] reportedly associated the term "Big Data” with large, heterogeneous and/or intensively streamed datasets. In this session, we make a balance of the role of Big Data in Models and Technologies for ITS systems through sharing experiences and case studies ranging from “classical” (but sometimes massive) datasets like vehicle counters to cellphone, Bluetooth or WiFi based traffic counters; from structured and well-defined data types such as smartcard social demographic information, to unstructured and subjective data, such as text and social media; from infrastructure and surveillance data (e.g. cameras) to contextual and crowd sourced data, such as weather information, environmental sensing.

Are we taking advantage of such data to the best? What are the greatest challenges and limitations? What are the key research needs for the coming years?
