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)

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

C2C-Applikation

VComVISSIM

New Programming Interface in VISSIM for C2C

Example Application

if veh.v < 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 < dx_grenz) then send_to_all (SpeedAlert, warn_pos)

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: 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

> 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

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
