Traffic Analysis Toolbox Volume IV: Guidelines for Applying CORSIM Microsimulation Modeling Software

Abstract

This report describes a process and acts as guidelines for the recommended use of CORSIM traffic simulation software in transportation analyses. The seven-step process presented in these guidelines highlights the aspects of a CORSIM analysis from project start to project completion. The seven steps in the process include: 1) scope project, 2) data collection, 3) base model development, 4) error checking, 5) calibration - comparing model MOEs to field data (and adjusting model parameters), 6) alternatives analysis, and 7) final report. Each step is described in detail and an example problem applying the process is carried through the entire document. The report appendices contain detailed information covering areas such as: fundamentals of CORSIM model theory, an overview of CORSIM capabilities and limitations, guidance on the initialization period, a discussion on actuated signal control in CORSIM, coding techniques for complex situations, and run-time extension. This is the fourth volume in a series of volumes in the Traffic Analysis Toolbox. The other volumes currently in the Traffic Analysis Toolbox are: Volume I: Traffic Analysis Tools Primer (FHWA-HRT-04-038) Volume II: Decision Support Methodology for Selecting Traffic Analysis Tools (FHWA-HRT-04-039) Volume III: Guidelines for Applying Traffic Microsimulation Software (FHWA-HRT-04-040) 17.
