TSIS-CORSIM 2023

The Reliable Microsimulation Tool That is Credible, Cost-effective, and Easy-to-use

Compliance with HCM and FHWA’s Traffic Analysis Toolbox

TSIS-CORSIM has been used for conducting research and applied by thousands of practitioners and researchers worldwide for over 30 years, embodying a wealth of experience and maturity.

Compliance with the Highway Capacity Manual

TSIS-CORSIM is in compliance with the Highway Capacity Manual Chapter 6: Interpreting HCM and Alternative Tool Results. It is able to open .trf files exported by the several HCS modules, which allows supplementing the analysis of the HCM for modeling characteristics not covered by the HCM methodology.

FHWA Traffic Analysis Toolbox

Volume 4 of the Traffic Analysis Toolbox (CORSIM Application Guidelines) is available on the Federal Highway Administration (FHWA) traffic analysis tools page.

New Bings Map Interface

Bing Maps can be added as a background to your TSIS-CORSIM 2023 network.

Easily navigate to a specific street, city, or zip code by entering keywords.
The map location can be changed at any time, making it easy to make small adjustments to the location of your network.

Change between a typical map or aerial view under the Map Photo Type selection box.

Links created in TSIS are automatically scaled to match the Bing Maps scale. This can be disabled in Preferences.

Integration with HCS and TRANSYT-7F

TSIS-CORSIM is bundled with TRANSYT-7F (T7F) software for signal timing optimization.

It takes one click to export an arterial corridor model and settings in TSIS to T7F, which which can optimize signal timings and coordination. T7F simulation results and timings can be visualized as an animation in TRAFVU or easily exported back to TSIS-CORSIM. TSIS-CORSIM can also open .trf files exported by HCS modules, including Freeways and Streets.

TSIS-CORSIM Integration

Two-Lane Highways

TSIS-CORSIM can simulate single-lane roads such as two-lane highways and generate service measures compatible with the 7th Edition of HCM (Follower Density – FD) and the 6th Edition of HCM (Speed and Percent-Time Spent Following – PTSF). The passing algorithm parameters can be adjusted to calibrate the model. Configurations with passing zones or passing lanes can be simulated.

Connected and Automated Vehicles (CAV)

New input parameters for CAV Market penetration and base calibration factor with a partial degree of connectivity and automation on freeway links.

Redesigned Vehicle Trajectory

Track vehicle trajectories on a single or multiple links at once, while monitoring using one of several performance measures.

Vehicle Trajectory Dashboard

New Environmental Measures

Graphical reporting of environmental measures such as emissions and fuel efficiency by vehicle class.

TSIS Enviornmental Graph

Unsignalized Intersections

A properties dialog for stop / yield signs that allows graphically setting two-way, all-way, or other configurations for intersections. Yield or stop signs can be selected for each approach individually.

Network Data

Integrated Files
Network Data is now edited through the CORSIM (.trf) file, which means no need to keep a separate TRAFED (.tno) file

Integration

Enhanced Project File Compatibility
Directly open files from:
TSIS version 6.3 (TRAFED editor)
HCS Streets, Unsignalized Intersection modules, and Freeways (HCS7 and newer)

Performance

Toll Plaza
TSIS-CORSIM can model toll lanes with different settings, including automatic and manual booths, plaza lane-changing logic, free lanes, temporary lane closures, vehicle restriction on selected lanes, and animations and all lane-based MOEs.

Unsignalized Intersections

Bing Maps
Bing Maps support for the background of TRAFVU networks
Improved performance for network background images

Input Validation
Improved input validation to ensure modeling accuracy

Improvements
Other bug fixes and improvements

User Interface

Updated Design
A modern user interface for Windows 10 and 11 Usability

Undo/Redo Commands
Undo (Ctrl+Z) and Redo (Ctrl+Y) commands are available for all dialogs, including the Map View interface and Text Editor tool

Quick Jump Search
Quickly search through the extensive CORSIM text report

Scenario Generation with Growth Factors
Ability to modify all node volumes and/or turn movement volumes with a growth factor

Curvature
Graphical road curvature can be added to links to show a more accurate representation of a network for modeling
