Transportation and air-quality issues are complex, coupled with the dy
namic evolution of regulations, trends, and implications. The need for
planners and decision makers to access current and expert information
on air-quality trends, transportation planning, and applicable legisl
ation to assist them in transportation-related air-quality management
encouraged the development of the Transportation-Related Air-Managemen
t System (TRAMS). This hypertext, hypermedia system enables planners a
nd decision makers to dynamically retrieve current information at thei
r desktops. Transportation and air-quality information on a wide varie
ty of related topics is organized into a branching hierarchy and prese
nted in a consistently structured hypertext environment, allowing user
s to direct their own path through the resources integrated in the sys
tem design including graphics, glossary terms, crossreferences, origin
al text materials, and expert contact information.
