Kakihara, M. and Sørensen, C. (2001). Expanding the 'mobility' concept. SIGGROUP Bull. 22, 3 (Dec. 2001), pp. 33-37:
"The train and airline infrastructures are highly integrated with ICTs such as electronic reservation systems and traffic control systems. It is therefore important to recognize that the fundamental nature of technological revolution in the late twentieth century is the dynamic and complex interplay between old and new technologies and between the reconfiguration of the technological fabric and its domestication (...).This paper concerns the concept of mobility, which manifests such a transformation of our social lives combining new and old technologies. It is now widely argued that our life styles have become increasingly mobile in the sense that the speed of transportation and hence geographical reach within a given time span is dramatically augmented by modern technological developments and sophistication such as train and airplane systems."
