Telecommunications and travel relationships: a review

A large body of research on the interactions of telecommunications and transportation has emerged in recent years, an outcome of the pace of development in electronics technology. Three types of interactions are noted: substitution, complementarity and enhancement, by order of their popularity. The paper reviews the knowledge on the relationships between the two systems through the analysis of applications of telecommunications technology for remote work, teleconferencing, teleservices, mobile communications and electronic mail transfer. It points to the importance of assessing future modifications of travel rather than focusing on the promises of substitution. The review also assesses the methods applied in this area and suggests further research, in view of some conceptual and practical issues.
