> VISSIM 5.40: Pedestrian Simulation

> Preview: VISSIM-R (6.00)

> Paramics Network Importer

> SIDRA Model Importer

VISSIM 5.40

> New Red Icon for VISSIM

> Release notes now in PDF format


VISSIM 5.40: Vehicle simulation

> Blocking time distribution for on-street parking



> Link filter for vehicle record



> Additional driving behavior parameters:> lateral behaviour parameters


What’s my benefit?No change if lessAngle right/ angle left


> New Driving Behaviour State: CloseUp> provides a smoother deceleration process up to a standing

obstacle, avoiding unrealistic acceleration after the leading vehicle has (almost) stopped

> Derived from emissions modelling with Toyota fleet

> Vehicles slow down from max look ahead distance in CF


> Vehicles slow down from max look ahead distance in CF behaviour

> Cooperative Lane Changing

> Vehicle pays attention to x number of upstream vehicles in necessary lane change

> Previously only one vehicle considered as object becomes trailing vehicle



> Cooperative Lane Change



> Advanced Merging> better tactical look ahead by merging vehicles and by cooperative trailing vehicles

on the target lane

> Utilises Number of Observed vehicles on Car Following Behaviour

> more vehicles to change lanes earlier

> increases the capacity


> increases the capacity

> reduces the probability of standing vehicles waiting for a lane change.

VISSIM Pedestrian Simulation: O-D Matrix Dialog


> Entering and editing of pedestrian demand in matrix format

> Remember: Flows are in persons/hour !!!

> Automatic creation of Input and Routes

> Pass data between spreadsheets and VISSIM

VISSIM Pedestrian Simulation: O-D Matrix Dialog

> Time intervals> Input and route need share the same interval

> Synchronization of Route splits and OD flows

VISSIM Pedestrian Simulation: Level of Service

>New option for LOS display: A pedestrian can be "spread" over multiple cells (useful if the cells are smaller than a pedestrian).

>The radius of this approximated circle can be 1->5 cells.
