The main tasks for this overview of transportation development are the provision and interpretation of information on the unfolding of the transportation systems. What have been the processes at work? What explains the similarities and differences from here to there and among systems? Big...

This paper studies relative time savings between vehicles unequipped and equipped with route guidance and navigation systems. In particular, the report investigates to what extent relative travel time savings decrease as the percentage of equipped vehicles increases. In addition, some other...

This is the final report of Phase I studies of road infrastructure requirements for small innovative highway vehicles. Project reports previously published provide statements of approaches and findings, and these provide the basis for the present report which strives for...

Our purpose is to highlight an overlooked impact of transportation improvements -- the ways improvements stimulate innovation and the development of technologies. Social and economic progress is then achieved through the use of new technologies. Does consideration of technological impacts...

Technological improvements over the centuries have yielded cheaper, faster, and better (less polluting, quieter, safer, more reliable) transportation services. Stories about this glorious history are usually in the language of vehicles, facilities, and propulsion. Wheeled wagons were in use at...

This paper investigates the ways in which transportation improvements enhance production. The production of residential housing is used as a case at point. Several approaches to analysis are proposed, and an approach is adopted emphasizing productivity improvements from technological change....

Until recently, truck drivers and their dispatchers have relied on public telephones and voice radio systems to communicate with each other. Today, however, vendors are beginning to offer new technologies for determining the positions of trucks and communications to and from trucks. Eighteen...

Considerations of the impacts of electronic technologies on transportation usually focus on substitution of communications for travel, especially telecommuting. This topic is reviewed briefly, followed by consideration of electronic technology-induced changes in the structure of firms, work by...

I critique the innovation processes that yield transportation’s technologies, and to aid my analysis I look back to take advantage of the accumulation of experiences and insights marked by the millennium. I identify supply, transport, and user systems. Transport systems move things,...
