TSIS-CORSIM™ > Overview


TSIS-CORSIM version 6.3 plus TRANSYT-7F has now been mailed at no cost to all registered users with a current support subscription. It is also available for purchase on this site. Version 6.3 offers a variety of new features including the Streets Editor, high-occupancy toll (HOT) lanes, advanced toll plazas, interactive lane alignment in TSIS Next and adaptive cruise control.

Traffic Software Integrated System – Corridor Simulation

TSIS 6.3 was released in August 2012, and has been mailed to all offices with a current support subscription. 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.

Volume 4 of the Traffic Analysis Toolbox (CORSIM Application Guidelines) is available on the Federal Highway Administration (FHWA) traffic analysis tools home page. Refer to the McTrans home page for a link to the FHWA traffic analysis tools.

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.
