The first update (CORSIM build 512) to TSIS 6.2 was released in December 2010 as a downloadable patch. TSIS 6.2 was originally released in February 2010, 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.

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:

• Verification and validation of other software
• Surrogate for field data collection
• Public presentation and demonstration
• Land use traffic impact studies and access management studies
• Freeway and surface street interchanges
• Signal timing and signal coordination
• Diverging diamond interchanges (DDI)
• Emergency vehicles and signal 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
• Two-lane highways with passing and no-passing zones
• Incident detection and management
• Queuing studies involving turn pockets and queue blockage
• Toll plazas and truck weigh stations
• Origin-destination traffic flow patterns
• Traffic assignment for surface streets
• Statistical output post-processing
• Run-time extension (RTE) for researchers
• Simulation of right-hand drive or left-hand drive
• Import files from HCS (Signals, Unsignal, Interchanges, Freeways, Ramps, Weaving)
• Import files from TRANSYT-7F*, to quickly generate a network with dozens of signalized intersections
• Export files to TRANSYT-7F*, for signal timing optimization and intersection level of service
