COURSE OBJECTIVEDemonstrate the benefits of 4D visualization through a series of case studies

4D Visualizations – Not just a pretty picture

WHAT ARE 4D VISUALIZATIONS

4D visualizations merge project-specific traffic analyses, virtual 3D environments, and proposed geometric designs to enhance project delivery.

4D Visualizations – Not just a pretty picture

Vissim Traffic Model• Vehicular, pedestrian, bicycle data • Signal timing / phasing• Roadway geometry• VISSIM traffic analysis• Calibrate & validate

3D Environment• CAD drawings/dtms• Survey data• Contours• Drape aerials

Add 3D Elements (buildings, bridges, signs, trees)• Build models and apply textures• Import from Sketchup, 3D Studio Max, Revit

BUILDING THE MODELS

Merge into Interactive

Model

4D Visualizations – Not just a pretty picture

• Optimize design / value engineering• Evaluate construction staging impacts• Present aesthetic alternatives• Public education and buy-in• Alternatives evaluation• Depict multi-modal operations• Demonstrate impacts to adjacent properties• Expedited project approval process
