PTV Vissim use cases

Vissim is a microscopic, time step oriented, and behavior-based simulation tool for modeling urban and rural traffic as well as pedestrian flows.

Besides private transportation (PrT), you may also model rail- and road-based public transportation (PuT).

The traffic flow is simulated under various constraints of lane distribution, vehicle composition, signal control, and the recording of PrT and PT vehicles.

Vissim allows you to test and analyze the interaction between systems, such as adaptive signal controls and route recommendation in networks.

Simulate the interaction between pedestrian streams and local public and private transport, or the evacuation of buildings or stadiums.

Vissim may be deployed to answer various issues. The following use cases represent a few possible areas of application:

Comparison of junction geometry

• Model various junction geometries
• Simulate the traffic for multiple node variations
• Account for the interdependency of different modes of transport (motorized, rail, cyclists, pedestrians)
• Analyze numerous planning variants regarding level of service, delays or queue length
• Graphical depiction of traffic flows

Traffic development planning

• Model and analyze the impact of urban development plans
• Have the software support you in setting up and coordinating construction sites
• Benefit from the simulation of pedestrians inside and outside buildings
• Simulate parking search, the size of parking lots, and their impact on parking behavior

Capacity analysis

• Realistically model traffic flows at complex intersection systems
• Account for and graphically depict the impact of throngs of arriving traffic, interlacing traffic flows between intersections, and irregular intergreen times

Traffic control systems

• Investigate and visualize traffic on a microscopic level
• Analyze simulations regarding numerous traffic parameters (for example speed, queue length, travel time, delays)
• Examine the impact of traffic-actuated control and variable message signs
• Develop actions to speed up the traffic flow

Signal systems operations and re-timing studies

• Simulate travel demand scenarios for signalized intersections
• Analyze traffic-actuated control with efficient data input, even for complex algorithms
• Create and simulate construction and signal plans for traffic calming before starting implementation
• Vissim provides numerous test functions that allow you to check the impact of signal controls

Public transit simulation

• Model all details for bus, tram, subway, light rail transit, and commuter rail operations
• Analyze transit specific operational improvements, by using built-in industry standard signal priority
• Simulate and compare several approaches, showing different courses for special public transport lanes and different stop locations (during preliminary draft phase)
• Test and optimize switchable, traffic-actuated signal controllers with public transport priority (during implementation planning)
