Microsimulation Applications Guidebook

KAI was selected by Caltrans to develop a Microsimulation Software Applications Guidebook for the State of California. This guidebook was later expanded to cover national practice under contract with the Federal Highway Administration.

The guidebook covers:

  • microsimulation fundamentals
  • management of microsimulation projects
  • data preparation
  • calibration of microsimulation models
    *analysis of microsimulation model results

The guidebook treats the statistical analysis of microsimulation output and, in addition, covers the presentation of microsimulation results to the general public in printed and electronic formats.

In addition, KAI was also the technical lead in the development of Volume III of the Traffic Analysis Toolbox: Guidelines for Applying Traffic Microsimulation Software. The 7-step process presented the aspects of microsimulation 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 - compare model MOEs to field data (and adjust model parameters)
  • 6 - alternatives analysis
  • 7 - final report.

Each step is described in detail and an example problem applying the process is carried through the entire document.

The appendices to the report contain detailed in information covering areas such as: traffic microsimulation fundamentals, confidence intervals, estimation of simulation initialization period, simple search algorithms for calibration, hypothesis testing of alternatives, and demand constraints. The guidebook treats the statistical analysis of microsimulation output.

These guides were reviewed by FHWA experts and a volunteer panel of international experts in microsimulation research, software development, and application.
