In the January/February 2007 issue of Public Roads magazine, Vassili Alexiadis co-authored a article with James Colyar and John Halkias about a public-private partnership that is working to improve traffic microsimulation technology. The article, titled A Model Endeavor, is available on the Public Roads web site. 
This primer provides an overview of traffic analysis tools in the transportation analysis process. Different categories of traffic analysis tools are defined, and the challenges and limitations of using traffic analysis tools is presented. A specific comparison between Highway Capacity Manual (HCM) analysis and traffic simulation-based analysis is provided. Criteria for selecting the appropriate type of traffic analysis tool are described. This is the first volume in a series of volumes in the Traffic Analysis Toolbox. The other volumes currently in the Traffic Analysis Toolbox are: Volume II: Decision Support Methodology for Selecting Traffic Analysis Tools and Volume III: Guidelines for Applying Traffic Microsimulation Modeling Software.
The purpose of this Decision Support Methodology for Selecting Traffic Analysis Tools is to provide an overview of the role of traffic analysis tools in transportation analyses and to present a detailed methodology for selecting the appropriate tool for the job at hand. The report describes the selection process including selection criteria and worksheets that can be used in applying the selection process.
Guidelines for Applying Traffic Microsimulation Modeling Software provides a recommended process for using traffic simulation software in transportation analyses. The guidelines provide the reader with a seven-step process that begins with project scope and ends with the final project report. It is hoped that these guidelines will assist the transportation community in creating a more consistent process in the use of traffic simulation software.
