Technical Details

Efficient network editing

Easy-to-use and intuitive graphical network editor
Creating and editing traffic networks over background images (e.g., aerial photographs and CAD drawings in different digital formats) to allow for exact modeling of networks
Exact modeling of lane geometry and network element positions (signal heads, regulatory signs)
Possibility of creating VISSIM networks by exporting from VISUM (together with travel demand matrices and route information) By pre-defining standard intersections in VISUM it is possible to quickly create larger traffic networks for microscopic simulations
Efficiency is improved with the help of the "read additionally"-function:

Several users can access and edit data on one large project at the same time
Sub-area networks can be aggregated to one large network
The user can create a library of sub-area networks or access pre-defined standard intersections

The vehicle behavior model is based on the Wiedemann car-following model
Time steps as low as 1/10 second
Modeling options for urban and freeway traffic
Powerful lane-changing behavior models provide the user with realistic modeling of various merging situations (e.g., merge and weaving areas)
Modeling parallel vehicle flows, such as

Expandable collection of different vehicle types and user-defined changes of driving behavior (e.g., desired speed distribution, acceleration and car-following behavior)
Selecting between different types of traffic demand modeling:

Static routing based on turning movement data/intersection counts
Free route choice using dynamic assignment: transparent dynamic assignment module offering a variety of parameters, using trip purpose-related and time-dependent origin-destination matrices True multi-class networks, i.e., route choice can be determined for each vehicle type, thus allowing pedestrian precincts, bus lanes, HOV lanes, driving restrictions for trucks, etc to be modeled

Uses conflict areas and priority rules to model non-signalized intersections, conflicting movements at signals or keep-clear-areas.
Highly-detailed modeling of intersections of any kind of geometry
Integrated GUI supported ring/barrier-based traffic signal controller for North American style signal control
Fixed time signal controls and any vehicle-actuated signal control can be coded with VAP, the traffic control language integrated into VISSIM.
Interfaces to adaptive signal controllers, such as SCATS, SCOOT and many others
Econolite ASC/3™ Software in the Loop controller
Application of VAP to model Intelligent Transport Systems (ITS) and regional control operations such as dynamic speed control or alternative route guidance systems
Numerous functionalities for testing vehicle-actuated control operations via manual detector activation and reproducibility using macros

Wide range of user-defined parameters such as number of vehicles, average speed, travel time, delay time and queue length
User configurable selection of parameters (average values, distributions) and select between database or text file as output format
Convenient access to the most important parameters by means of pre-defined node evaluations.
Highly aggregated output data such as number of vehicles and delays within the entire network.
Automatic generation of Microsoft Excel® evaluations to be used for reporting
Determining signal control parameters such as min/max and average green time per signal group/phase, waiting time after detector calls and display of dynamic signal timing schedules and user-defined parameters
Possible export of simulation results to VISUM for display of macroscopic parameters within the network (eg flow maps, flow bundles, node flows)

Visualizing vehicle movements within the network in 2D and 3D
Large vehicle library with various 3D models
Display of vehicle movements from the driver's seat in 3D mode
Realistic 3D display by importing 3D objects and modelling simple static 3D objects using the optional module V3DM
Creating AVI films in VISSIM
Free VISSIM-Viewer for display of short simulations or animations of network files.
Color coding of attributes and vehicle status for the evaluation and optical differentiation of complex traffic flows.
