NCHRP Synthesis 20-05/Topic 25-01 [Final (Synthesis)]

Applications of 3-D and 4-D Visualization Technology in Transportation
[ NCHRP 20-05 (Synthesis of Information Related to Highway Practices) ]

  Project Data

This synthesis describes the application of computer graphics technology to transportation practice. It will be of interest to transportation planners, facilities design and construction personnel, traffic engineers, and other officials concerned with administration, public information, legal aspects, right-of-way, maintenance, operations, and safety of transportation facilities. This report of the Transportation Research Board describes the use of 3-D (artist's concepts and image composites) and 4-D (animation) visualization applications in transportation agencies; however, since there are presently only limited applications, it is, in fact, a primer, providing information on the required hardware and software, as well as on costs, production time, and issues of complexity. More detailed information is provided on how data bases are assembled, various types of imagery, how the visualization image is generated, rendering and animation programs, printers and other output and postproduction activities. An extensive glossary is also included.  The report for this topic can be purchased at http://www.trb.org/news/blurb_detail.asp?id=3328
