Big Data One major influence of ICT is the ability to manage and interact with the transport system in real time. Initially there was strong ‘top down’ development of sophisticated traveller information systems, using on-line journey planners – using what can be called ‘formal information’. However, the emergence of smartphones has led to technological developments from ‘bottom up’ user generated ‘informal’ information; for example combining smartphones with GPS technology. What are the obstacles for sharing and collaborating in Big Data? What regulatory adjustments need to be developed and adopted? How to overcome the privacy issues in collecting and using Big Data for the public good benefits? • The role of public authorities in new mobility solutions.• Shared modes are most likely to be successful if the authorities enable a ‘big bang’ introduction. • Smart mobility means Big Data, but Big Data does not necessarily make mobility smart. • There are several obstacles in EU Big Data sharing that currently prevent collaboration. Social media refers to a set of web-based technologies and applications designed for and created through social interaction. The digital era allows for an accumulation of an ever growing mass of data sets and personal digital footprints, which seem to encompass humanity’s every move and intention in both the physical and virtual spaces. The information revolution quickly received the attention of the private sector through the exploitation of the rapidly growing web 2.0 social media. However, government agencies are still in its nascent stage globally, and is heavily reliant on its off-line practices and experiences. There are several obstacles in EU Big Data sharing that currently prevent collaboration. Privacy aspects (legislation) that prevent Big Data company providers from sharing data (companies such as Google and Microsoft); Data ownership by Big Data private companies that are reluctant to share their own data; Sharing data between public and private providers; Lack of sharing protocols and legislation tailored to EU Big Data that determine how the sharing of data needs to be done; Lack of understanding the benefits of Big Data sharing by transport operators and authorities; Real-time data obtained from users while at the same time preventing privacy exposure.
