MTJ Engineering and One Source Consultings Craig Donze, P.E. provided the Wisconsin DOT with modern roundabout expert analysis, review, traffic analysis, and design services including business access alternatives optimization to minimize impacts. A major component of this project was the public outreach effort which called for presentations to the community and public officials as well as 3D visualization of design alternatives. Special attention was paid to recent OS/OW issues and design parameters for large vehicle turning movements. Though a construction date has not been determined, this roundabout was approved for construction in 2011.

Visualizing your project with MTJ

Overcoming doubts about aesthetic, technical, and/or safety choices in engineering designs can be challenging. MTJ Engineering can provide visually rich, informative presentations and full 3-D visualization services to grant your public and affected decision makers the ability to understand and grasp a design's quality and intent.

Graphically illustrative and concise 2D and 3D visuals provide:

  • Easily understood graphical representation of proposed plans.
  • Accurate representation of impacts.
  • Valuable tool for public understanding and involvement.
  • Communication with participants whom are unfamiliar with technical drawings.
  • An opportunity to visualize aesthetic choices.
MTJ Engineering utilizes modern 3D visualization technologies and techniques, combined with 17 years of traffic engineering experience, to provide presentation, concept, and analysis materials of high quality at a competitive rate which are grounded in sound engineering principles. Visualizations can include differing levels of detail from a sketch of a specific element to a rendering of a complete design and it’s surroundings to include full traffic modeling analysis.
