| 摘要： | In this project we employed state-of-the-art technology for developing visualization tools for teaching highway design. Specifically, we used photolog images as the basis for developing dynamic 3-D models of selected geometric elements. The resulting 3D-visualization toolbox links video clips of various road sections, with animated graphs representing their horizontal and vertical alignments. By the simultaneous display of the windscreen view of a roadway, along with the plan and profile graphs, the toolbox allows the user to study the effect on continuity and esthetics of combining specific plan and profile elements. The visualization toolbox consists of 17 video clips, illustrating various design issues summarized in the literature. Some of the issues highlighted in the toolbox include broken back horizontal curves, diving, jumping, fluttering, coordination of vertical and horizontal alignment as well as consistency in alignment. Currently the full visualization toolbox is only available on a CD ROM disc, however, a portion of the toolbox can be accessed through the following website- WWW.engr.uconn.edu/-qarrick/VisToolBox/VidClipDescr. |
