VISSIM is a microscopic, time step and behavior based simulation model developed to analyze the full range of functionally classified roadways (including roundabout, rail road crossing and toll plaza) and transit operations. It is capable of modeling traffic with various traffic control measures in a 3D environment. VISSIM assists in comparing different alternates in designing roundabout, at-grade intersections, and high-type traffic interchanges.

VISSIM can model integrated roadway networks found in a typical corridor as well as various modes consisting of general-purpose traffic, buses, HOV, HOT, light rail, heavy rail, trucks, pedestrians, and bicyclists. The following components and strategies can also be modeled in VISSIM: Variable Message Signs (VMS), ramp metering, incident diversion, transit signal priority, lane control signals, dynamic lane control signs, etc. For more information on traffic simulation, click the simulation page for sample images and video clips.

How can VISSIM make a difference for your project?

The Traffic Group, Inc. has had tremendous success using simulation technologies before Planning Boards, citizen forums and review agencies. These models help visualize traffic operations and actual site impacts. The model is also vital in evaluating operations of access points and/or proposed road improvements in before and after scenarios.

The costs associated with the preparation and validation of these models can easily be justified with time saved in the approval process and can reduce controversy in public forums by visualizing the acceptable operations of a development proposal.
