New Developments in VISSIM

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

2
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

3
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
.dll
5
Example Application
incident area
if veh.v lt v_warn then send_to_all (SpeedAlert,
veh.pos) if receive (SpeedAlert (warn_pos))
then if relevant (warn_pos) then
veh.color red veh.speed 50
km/h if (Distance lt dx_grenz)
then send_to_all (SpeedAlert, warn_pos)

• 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

VISSIM 5.1 Main areas of work

• New pedestrian model
• Multi-Threading
• SUMSIM improvements
• Conflict area behaviour

10
Multi-Threading

• Speedup on multi-core processor and
  multi-processor computers
• Shared memory
• Speedup depends on network and number of vehicles

11
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)

12
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)

13
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
