NYSDOT explored the use of new symbology
in the approach corridor of roundabouts, replacing conventional left-turn arrows in most instances.
To fulfill the evaluation test procedures required
by the Federal Highway Administration, NYSDOT installed the new fish-hook symbology in
several constructed roundabouts to evaluate its
effectiveness and created an interactive multimedia simulation to evaluate driver response in a
The challenge of the project was to create a
usable simulation test that would allow NYSDOT
to measure drivers’ responses to the fish-hook symbology compared to the conventional left turn
arrow. The simulation had to look good, be true to
scale, and be as unbiased as possible.
NSYDOT used MicroStation, InRoads, and
ProjectWise in this project. All of the 3D
modeling, material assignments, scripting, and
frame generation could be done directly in
MicroStation. Now that this model is complete, it
can be used to generate graphics for other communication purposes.
This entire project was, in essence, a 3D visualization. The addition of multimedia authoring put the
MicroStation animations into an effective and
Commenting on the department’s use of
MicroStation in the project, Thomas Fischer,
a visualization technician at NYSDOT, said,
“MicroStation can produce much more than traditional line drawings. Having the ability
to create a 3D model, assign photo-realistic materials, create simple or complex animation scripts,
and generate high-quality animation frames, all
from within one software package, is quite convenient. It eliminates the need to go back and
forth between multiple software packages.
Continued Fischer, “I've repeatedly seen how ren-
derings and animation more quickly communicate
project goals and objectives than conventional
CAD drawings. Visualization brings a project to
life long before the construction process begins. It
can add vision and value to virtually any project.
Imagination is one’s only limitation. ” ;
