VISSIM is a microscopic, behavior-based multi-purpose traffic simulation program. For many engineering disciplines, simulation has become an indispensable instrument for the optimization of complex technical systems. This is also true for transportation planning and traffic engineering, where simulation is an invaluable and cost-reducing tool.
It offers a wide variety of urban and highway applications, integrating public and private transportation. Even complex traffic conditions are visualized in an unprecedented level of detail providing realistic traffic models.
Consequently, traffic engineering expertise, combined with 3D animations, guarantees convincing presentation for both technical experts and decision makers, in particular when important decisions on costly projects have to be taken. VISSIM convincingly shows how effective a projected measure might be regardless of whether a new road is going to be constructed or a new tram line is being planned. The figures speak for themselves: In the meantime VISSIM is used in more than 70 countries worldwide.
We are excited about the improvements in VISSIM 5.00, which is the result of many hours of focus group feedback. Some of the most important enhancements are:

- New VISUM/VISSIM Interface (ANM)
- New Ring Barrier Signal Controller for North America (RBC)
- Multiple rings/barriers
- 8 Time of Day Plans/Patterns
- Advanced detector mapping
- Volume-Density functions
- Comprehensive Transit Signal Priority and Preemption
- Link behavior types and link display types are now separate, providing more flexibility
- User selectable maximum resolution for background images in 3D
- Improved Analyzer
- Ability to select reports to be generated
- Pause, cancel, and restart report generation in Analyzer
- New node type to distinguish between nodes used for evaluation or dynamic traffic assignment
- Multiple COM interface additions
- V3DM 1.40: Import of Google SketchUp (*.skp), and AutoDesk 3D Studio and DWF models
