Why Vissim - Vissim Care

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.You can comfortably test and analyze the interaction between systems, such as adaptive signal controls, route recommendation in networks, and communicating vehicles (C2X).Simulate the interaction between pedestrian streams and local public and private transport, or plan the evacuation of buildings and entire 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 controls with public transport priority (during implementation planning)
