How using Big data sets for eliciting needs and defining
mobility strategies? Could we create some automatism in the
mobility services system crossing Big data?

Big Data, Social Networks and Travel
Behaviour
Pnina Plaut
Associate Professor at the Faculty of Architecture and Town Planning Technion
Action Chair Social networks and Travel behaviour COST Action TU1305

New Social Structure
People have a wider spatial distribution of social networks than in the past.
A larger set of social contacts are active today than in the past and they overlap less in
spatial terms.
The appearance of virtual social networks such as Facebook and changes in working
patterns (home/hub-based, shorter working week days) have resulted in intertwining of
leisure activities with other daily routines.
The Result
More complex mobility patterns.
Strong links between lifestyles and personal travel
in the context of continuing social
and technological change.

Big Data
People are now generating new (large) data sets -
tagged to space and time.
We can extract from passive data sets, like smart travel
card data of individual trips in public transport systems
or from mobile phone service companies.
Using representations and data that are digital, we can
create images about what happens where and when in
cities.

The Data Challenges
We live in a world that is fast becoming digital in all its dimensions
Social networks and travel behaviour analysis can draw upon
active collection of data : surveys, questionnaires, or interviews.
-Ego-centric approach
-Whole network approach
Where do we draw the boundaries and who is included in the
analysis ?

 Develop and adhere interoperable (global) data standards
 because of the wide range of systems from which these data are created
 significant challenge to the development of data-driven intelligent mobility services
 Understand content of data - description of the data available
 each data collection is based on harmonised metadata profiles*
 data elements (description of a dataset in a minimal but adequately way),
 wordings and semantics,
 predefined categorisations – transport specific
 data field names,
 data value type,
 data field lengths
 Understand structure of data – description of the technical format of the data sets
 following data formats are currently foreseen for different transport domains**
 DATEX II for road transport data
 NeTEx and SIRI for public transport data
 TN-ITS and Inspire for geographical data
 Data formats currently valid and used for the creation of traveller information services
 Further work required for the formats for other transport data
