Segway for Information Workers The Segway Human Transporter is a self-balancing personal transportation vehicle that is clean (battery powered) and small (its footprint is 19 by 25 inches) so it can be used on sidewalks and inside buildings. Suppose the segway is introduced into a CBD, doubling the s
