How do the citizens travel from glom to glom in the novel, Masque?

Citizens travel by tube nexi, through which clear capsules silently hurtle at tremendous speed. Other means of travel include floaters, cruisers, speeders, and flyers; all designed to transport passengers from place to place at breakneck speed. There are also vertical tunnels with handholds that, through some mysterious vacuum technology, propel travelers from floor to floor of buildings in the gloms.
