5 Base Data for Simulation
If a type´s link from the 2D model to a 3D model is lost or if no 3D model is
assigned at all, in 3D mode the vehicle/pedestrian will be displayed as a
colored box with the dimensions as defined for 2D Geometry.
Due to the fact that 3D elements have a static length, a length distribution
can be defined by choosing different models with different lengths into the
same distribution.
The color as chosen in the distribution or for a class or PT line will be used
to fill all “designated surfaces” within the 3D model. Appropriate basic
models provided, these surfaces may be specified in the optional VISSIM
module “V3DM” (VISSIM 3D Modeler).
During the simulation VISSIM uses a vehicle path algorithm to determine
the location of subsequent elements within the network (trajectories). Thus
the turning behavior of segmented vehicles will look more natural the
higher the number of time steps per simulation second is set.
New VISSIM files have a default model distribution for each vehicle type.
The distribution for cars contains six different car models with different
percentages. These models are assigned to predefined 3D vehicle models
named CAR1.V3D ... CAR6.V3D. To change one of these default vehicle
models, rename the desired *.V3D vehicle file to one of these file names.
Caution: Changing a default vehicle model file causes different simulation
results only if the changed geometry values are passed into the Geometry
dialog by OK in the Select 3D Model dialog.
5.2.6 Dwell Time Distribution (PT Stops & Parking Lots)
The dwell time distribution is used by VISSIM for dwell times at
► parking lots which have to be defined per time interval for routing
decisions of the parking lot type, cf. section 6.4.4,
► stop signs and e.g. toll counters,
► PT stops. For PT vehicles (e.g. buses, trams) the amount of time they
stop at a passenger pick up area has to be defined for each PT stop or
train station if the time required for boarding and alighting is not
calculated by one of the methods provided.
A Dwell Time Distribution can be defined or edited by BASE DATA -
