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

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
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
