CORSIM Seminar for Beginners

This CORSIM Simulation Seminar will provide lectures on traffic flow theory, and hands-on software applications using the FHWA Traffic Software Integrated System (TSIS). Version 6 of TSIS implements arterial and freeway simulation in a Windows environment, which includes the TRAFED graphical input editor and the TRAFVU animation module. Each lecture will include software demonstrations and opportunities for students to use different components or modules of the software. Participants are encouraged to bring laptops with TSIS pre-installed for hands-on practice. A comprehensive workbook will be provided with the course. The agenda follows:

Day 1

Welcome and Introductions Roster sign-in, workbook distribution, agenda, schedule, informal discussion.
History, Scope and Software Components Overview of CORSIM background, scope, applications and resources; overview of TSIS component programs
Creating a New NETSIM Network Step-by-step creation of new surface-street traffic networks using TRAFED, or TSIS Next, or the Streets Editor
Using TRAFVU Detailed review of TRAFVU Viewer features including map adornments, scene manipulation, animation control, static graphics, custom preferences, overpass/underpass, curvature, performance measures, and animation files
Creating a New FRESIM Network Overview of general FRESIM concepts; followed by step-by-step creation of new freeway traffic networks using TRAFED, or TSIS Next, or the Freeways Editor
Pre-processors and Post-processors Demonstration of the TSIS Output Processor, pre-processing from HCS and TRANSYT-7F, post-processing and signal optimization from TRANSYT-7F
Using TSIS Next Demonstration of TSIS Next for traffic network creation, editing, and animation; discussion of advantages and disadvantages relative to the original TSIS

Day 2

Microscopic Simulation Theory Discussion of micro-simulation theory including multi-period analysis, initialization periods, vehicle entry headways, random number seeds, unsignalized intersections and toll booths
Hands-on Exercise (interchange) Hands-on practice for creating a combined surface and freeway network, using TRAFED or TSIS Next
Output Data Definition of CORSIM output parameters, interpretation of results, gravity model output, data station output, initialization output, customizing output, time period-specific output, cumulative output, expanded CSV output
Hands-on Exercise (surface street) Hands-on practice for adding new intersections to an existing network, actuated controller settings, saturation flow rate adjustments, multiple time periods, lane add/lane drop; using TRAFED or TSIS Next
Input Techniques and Calibration Discussion of freeway and surface street calibration, controlling lane utilization, factors affecting capacity, origin-destination volumes, and vehicle type properties
Hands-On Exercise (freeway) Hands-on practice for FRESIM sensitivity analysis, O-D volumes, option lanes, ramp metering, HOV/HOT lanes, truck bias lanes, incidents, work zones, adaptive cruise control, toll plazas, two-lane highways, and data stations
