Today digital technology is viewed as additive to the physical world: something that enhances but does not replace the use of physical infrastructure. However, this paper by Hugh Bradlow and Arjun Jayachandra, presented at the Low Carbon Transport on the Move Conference in May 2015, discusses the next wave of digital technology adoption that can potentially be substitutive for physical infrastructure.

In particular, the authors examine the impact of emerging information and communications technologies on the demand for roads over the next three to four decades.
