New Developments in VISSIM

Lukas Kautzsch, PTV AG – PTV Vision Users Group Meeting USA 2008


Vissim 5 0 main areas of work

VISSIM 5.0: Main areas of work

  • SUMSIM: Second generation of VISUM-VISSIM integration

  • Ring-Barrier Controller (RBC) to replace NEMA

  • New Build, Setup and Update system

  • Car2Car Communication


Car to car communication c2c c2x vii

Car-to-Car

Car-to- Infrastructure

Car-to-Car-Communication (C2C, C2X, VII)

  • Vehicles can communicate

    • with each other

    • with the infrastructure

  • Technology used:

    • WLAN (802.11p)

    • GSM, UMTS etc.

  • Applications

    • Warning, e.g. road works

    • Travel time measurement

    • Virtual speed funnel

    • Weaving assistance

    • Hard shoulder usage

    • Route guidance


New programming interface in vissim for c2c

C++ / Python

C2C-Applikation

get_speed() set_speed()

get_velocity()

get_position()

set_color()

...

send (vehicle, message) receive (vehicles, messages)

„connect ()“

sockets

VISSIM

VCom

cars in neighborhood of sending vehicle

New Programming Interface in VISSIM for C2C

.dll


Example application

Example Application

incident area

if veh.v < v_warn

then send_to_all (SpeedAlert, veh.pos)

if receive (SpeedAlert (warn_pos))

thenif relevant (warn_pos)

then veh.color = red

veh.speed = 50 km/h

if (Distance < dx_grenz)

then send_to_all (SpeedAlert, warn_pos)


Vissim 5 0 more improvements

VISSIM 5.0: More Improvements

  • Graphics:

    • Link display types

    • Sketch Up import through V3DM

    • Resolution of background images user definable

  • Network Editor:

    • Editing of segment nodes

    • Completion of broken routes much faster

    • Nodes for dynamic assignment and evaluation separated

  • Various improved details in the VISSIM Analyzer

  • Many additional access functions in the COM interface

  • Hyperlinks to hotline support form and FAQ in info dialog


Graphics link display types

Graphics: Link Display Types


Editing of segment nodes

Editing of segment nodes


Vissim 5 1 main areas of work

VISSIM 5.1: Main areas of work

  • New pedestrian model

  • Multi-Threading

  • SUMSIM improvements

  • Conflict area behaviour


Multi threading

Multi-Threading

  • Speedup on multi-core processor and multi-processor computers

  • Shared memory

  • Speedup depends on network and number of vehicles


Vissim 5 1 conflict area parameters

VISSIM 5.1: Conflict Area Parameters

  • Vehicle-class dependent gaps and safety distance factor

  • Stop line distance

  • Avoid blocking (percentage)

  • Observe adjacent lanes

  • Anticipate routes (percentage)


Vissim 5 1 more improvements

VISSIM 5.1: More Improvements

  • Vehicle-class dependent prohibition of lane change (per direction)

  • New signal time table editor for fixed time controllers

  • Dynamic Assignment: Use of real path travel times

  • Complete unicode support for filenames (for Russian, Chinese, Japanese)

  • HOT lane modeling

  • Handling of large background images (Tiling)

  • New 3D model selection dialog

  • Handling of 3D objects (grouping, moving in 2D)

  • Direct import of Sketch Up models into VISSIM (without V3DM)


Future development

Future development

  • Technical issues:

    • Further work on multi-threading

    • 64-bit version?

  • Modeling issues:

    • Further work on pedestrian simulation

    • Usability of dynamic assignment

    • Better parking model: improved multi-lane drop-off
