Definition and Introduction:
PTV Vissim is a microscopic multi-modal traffic flow
simulation software package developed by PTV Planung Transport Verkehr AG in
Karlsruhe, Germany. The name is derived from "Verkehr In Städten -
SIMulationsmodell" (German for "Traffic in cities - simulation
model"). PTV Vissim was first developed in 1992 and is today a global
market leader.
PTV Vissim is part of the PTV Vision Traffic Suite which also
includes PTV Visum (traffic analysis and forecasting) and PTV Vistro (signal
optimisation and traffic impact).
World Leading Software in
transportation:
PTV Vissim the World’s Leading
software because it is flexible, user friendly, Efficient graphics and many
more properties which are discussed below:
Scope of application
The scope of application ranges from various issues of
traffic engineering (transport engineering, transportation planning, signal
timing), public transport, urban planning over fire protection (evacuation
simulation) to 3d visualization (computer animation, architectural animation)
for illustrative purpose and communication to the general public.
Scientific award
PTV AG has founded a bi-annual scientific award for
scientific work related to PTV Vissim and other PTV products. Participation is
open for any researcher.
Microscopic simulation
"Microscopic simulation", sometimes called
microsimulation, means each entity (car, train, person) of reality is simulated
individually, i.e. it is represented by a corresponding entity in the
simulation, thereby considering all relevant properties. The same holds for the
interactions between the entities. The opposite would be a "macroscopic
simulation", in which the description of reality is shifted from
individuals to "averaged" variables like flow and density. The
corresponding product from the same manufacturer is called Visum.
Multi-modality
"Multi-modal simulation" describes the ability to
simulate more than one type of traffic. All these types can interact mutually.
In Vissim the following types of traffic can be simulated
·
Vehicles (cars, buses, and trucks)
·
Public transport (trams, buses)
·
Cycles (bicycles, motorcycles)
·
Pedestrians
·
Rickshaws
