Big data and new sensing and communication technologies are enabling the near-real time collection and transmission of massive amounts of transport data. This big data can be used across the transport sector for public transport, urban planning, traffic management, fleet logistics, vehicle monitoring, product development, and behavior studies. The potential impacts of big data for transport include more resource efficient, safer, better informed, less congested mobility with less delays; improved socio-economic and behavioral understanding; secure personal information exchange; forward-looking policymaking; and global leadership for the European transport industry.
