TSIS-CORSIM

Traffic Software Integrated System - Corridor Simulation

TSIS-CORSIM is a microscopic traffic simulation software package for signal systems, freeway systems, or combined signal and freeway systems.  TSIS-CORSIM requires Microsoft Windows and Microsoft Internet Explorer.  Click on the hyperlinks below for more information.

TSIS is an integrated development environment that enables users to conduct traffic operations analysis.  Built using a component architecture, TSIS is a toolbox that contains tools that allow the user to define and manage traffic analysis projects, define traffic networks and create inputs for traffic simulation analysis, execute traffic simulation models, and interpret the results of those models.

Capabilities of TSIS-CORSIM include:

• Land use traffic impact studies and access management studies
• Freeway and surface street interchanges
• Signal timing, coordination, and pre-emption
• Freeway weaving sections, lane adds and lane drops
• Bus stations, bus routes, carpools and taxis
• Ramp metering and HOV lanes
• Unsignalized intersections and signal warrants
• Incident detection and management
• Queuing studies involving turn pockets and queue blockage
• Toll plazas and truck weigh stations
• Origin-destination traffic flow patterns
• Verification and validation of other software
• Surrogate for field data collection
• Public presentation and demonstration

Extensive electronic documentation is available for free within the TSIS package.  The HTML help system uses the Internet browser to provide a powerful, flexible, hypertext-based help utility.  Context-sensitive help is available on numerous software screens.  Several Acrobat PDF users guides are available on the installation CD.

Funded by the FHWA throughout the last three decades, TSIS has evolved into a benchmark within the transportation profession.  It has facilitated greater understanding of traffic flow theory, while continuing to improve traffic operations as a result of its verification and validation of proposed designs.
