ABSTRACT
This chapter begins with a broad consideration of the issues associated with travel, communications and the relationships between them and thus possibilities for demand management. Following this, two common activities are considered which give rise to substantial amounts of travel but which might also be a focus for significant if not substantial amounts of substitution, namely working and shopping. The UK has seen a substantial increase in the amount of passenger distance travelled in the last quarter of a century 62 percent from 1980 to 2005. The postal service and land-line telephone have been longstanding features of modern society. The scale of transport demand impacts of teleworking clearly relates to the extent to which it is undertaken. The chapter presents potential significance of information and communications technologies (ICTs) and substitution for transport demand management and some of the challenges that are posed.
