Visualization Projects

I-590/Winton Road Diverging Diamond

Rochester, New York
 

Fisher Associates provided 4D traffic and visual simulations for the reconstruction of the I-590 and Winton Road Interchange. Complex VISSIM traffic modeling and simulations were provided for alternatives that included a triple left exit ramp and variations of partial cloverleaf interchanges. The final alternative involved an innovative Diverging Diamond Interchange, one of the first applications in the United States. The project was recognized by ITE and ACEC for transportation project achievement and innovative 4D virtual modeling technology for design optimization and public involvement.

 

Awards:

  • 2009 ACEC New York Gold Award (Studies, Research and Consulting Engineering Services category)
  • 2008 ITE Project Award I-590 Winton Road Diverging Diamond Interchange

I-81/ NYS Route 17 Interchange

Binghamton, NY

 

4D visualization models were developed for existing conditions and three proposed design alternatives for the reconstruction of this interchange. Virtual models integrated actual traffic operations and physical features such as roadway, slopes, bridges (including girders, piers, and abutments), retaining walls, pavement markings, noise walls, overhead signs, guide rail, lighting, and landscaping. Visualization models allow for dynamic and interactive simulation, as well as drive-through visualizations of the existing and proposed alternatives.

Syracuse Bus Transfer Hub

Syracuse, New York

 

The $12 million project located a downtown transit center in the central business district of Syracuse. The project comprises a weather protected urban bus transfer facility with 22 bus bays to accommodate major pulses. Fisher was responsible for complex Synchro and VISSIM traffic assessments for three alternatives that involved internal and external bus routing/transfers, street network analysis, and the conversion of Warren Street from a one-way to two-way street. The key component was the traffic assessment for the addition of a new fifth leg to the existing signalized urban intersection.

World Trade Center

New York, New York

 

Traffic analysis and visualizations were provided for the redevelopment plan to reconnect the adjacent roadway network through the former WTC superblock. This complex project determined the optimal traffic patterns to assist in the alternative selection and provided detailed 4D traffic virtual modeling. Unique features include analysis of large tourist volumes accessing the WTC Memorial, an optional pedestrian only Dey Street, and livery vehicles, specifically ‘black cars’ with attended security treatment at either end for entering and exiting this section of Dey St. The project entailed the use of VISSIM microsimulation models of operations at 10 intersections. Fisher Visualization was utilized to create detailed 4D virtual models of the project inclusive of actual vehicular and pedestrian traffic as well as roadway geometry, building structures, landscaping, and assorted street treatments.
