Advanced Analysis of Drivers' Responses   

Utilizing lectures, discussions and in-class demonstrations, Dr. Jeff Muttart will introduce you to scientific studies and analysis to answer the key questions involving aspects of driver behavior: reaction times (and delays), perception, visibility and impairment, among others. Topics will focus on obtaining a better understanding of what needs to be accomplished to assess the human role in the crash sequence.

You will be introduced to both the IDRR and V*Star software programs—tools you can use to help analyze driver’s responses—and will learn how to incorporate them into your crash reconstruction. The IDRR software is based on research from Jeff and others in the field. The V*Star software is a crash momentum software which also calculates uncertainty.

Topics Include

  • Perception-Response Time
  • Response to slow moving or stopped vehicles on multi-lane high speed roads
  • Nighttime recognition
  • Driver decision making
  • Interactive Driver Response Research (IDRR)
  • Gap acceptance for left turns, right turns, and through movements for drivers, riders, and pedestrians
  • Pedestrian walking speeds
  • Acceleration
  • Lateral acceleration (swerving) for cars, motorcycles, and commercial vehicles
  • Forward and backward acceleration of cars, motorcycles and commercial vehicles
  • Drivers’ responses to green and yellow traffic signals, deceleration choice, reaction time and probability of stopping


Law enforcement and private traffic crash investigators, claims adjusters, engineers, attorneys, safety officers, military investigative personnel, animators and graphic designers

Course Length

40 hours


You must have completed IPTM’s At-Scene Traffic Crash/Traffic Homicide Investigation course or its equivalent. It is strongly recommended that you have a minimum of five years of field experience in traffic crash investigation.

What to Bring


  • Laptop computer with Excel 2007 or newer with Windows XP and service pack, or newer (recommended for utilizing IDRR program) MACs - Office 2011 or newer
  • Scientific calculator


Upon successful completion, you will receive a three (3) month personal use license of “Interactive Driver Response Research” from CSS, LLC, to use the following:

  • IDRR (a human factors-based time/distance program)
  • V*Star (a momentum calculator that calculated uncertainty in a Monte Carlo-type analysis)

ACTAR Information

IPTM's Advanced Analysis of Drivers' Responses course is eligible for 40 ACTAR CEUs.




Schedule Changes

This schedule is subject to change without notice. If you have not received an official confirmation email prior to the first day of class, please contact us at (904) 620-4786 or before traveling or making airline reservations.

Registration and Fees

Full payment must accompany all registrations. You may register online and pay with your Visa, MasterCard, Discover or American Express credit card, or you may download a Registration Form and mail it to IPTM with a check.

Cancellation/Refund Policy

Complete the Cancellation Request Form and return it to IPTM. No telephone cancellations will be accepted. A 20% administrative fee will be assessed to all refunds if the cancellation request is received within 14 days of the course start date. In lieu of a refund, student substitutions can be made or a credit can be issued for a future course. No refunds will be given for no-shows. If materials for an online course were sent to the student, the appropriate materials and shipping costs will be deducted from the refund amount. Materials may be returned to IPTM in their original condition at the student's expense. Once IPTM has received and inspected them, the refund will be processed.

Due to the automated format of online independent study courses and Videos on Demand (VoDs), no refunds or substitutions can be made after registration.

Course Confirmations

A minimum number of registrations must be received for an in-person class to run as scheduled. When the minimum criterion has been met, written confirmation will be emailed to you. Please do not travel or make airline reservations until you receive written notification confirming that the course will run as scheduled.

Transportation and Lodging

Most locations are served by several major airlines. Ground transportation, food and lodging are the responsibility of the student. Special rates have been negotiated at select hotels in Jacksonville for IPTM students. For more information, please visit our Locations/Lodging page or call us at (904) 620-4786.
