Freeway and Reliability Analysis using the HCM6 and FREEVAL

This two-hour workshop will cover freeway analysis methods and software associated with the Highway Capacity Manual (HCM), 6th Edition, released in fall 2016. The focus of the presentation is on application and best use cases of the methods to real-world sites and problems, ranging from interchange analyses, to work zone lane closure and diversion scenarios, to whole-year reliability assessment of hard shoulder running, managed lanes, and ramp metering strategies. An overview and demo of the FREEVAL software will also be provided.

7:30AM – Welcome and Breakfast

8:00AM – Introductions and Course Overview

8:15AM – HCM6 Freeway Method Overview, Data Needs, and Calibration

8:45AM – HCM6 Reliability Analysis and MAP21/Fast Act Performance Measures

9:15AM – FREEVAL Software and Case Study Applications

9:45AM – Questions and Discussion

10:00AM – Adjourn

The event will be held at Kittelson’s Portland office, located at 610 SW Alder St, Suite 700. There is no cost to attend, but seats will be limited. Please RSVP if you plan on attending. For any questions, please contact Norma Jensen at (503) 535-7451 or

We look forward to seeing you there!

About the Presenters

Bastian Schroeder, PE, PhD Principal Engineer
Kittelson & Associates, Inc., Wilmington, NC
Dr. Bastian Schroeder is a principal engineer with Kittelson in North Carolina and manages the company’s research, development, and education group. He specializes in traffic analysis and modeling, data analytics and visualization, and traffic operations on surface streets, freeways and interchanges. He routinely applies multiresolution modeling solutions to multimodal transportation problems, and serves as a company-wide resource for QA/QC and senior advice for operations projects. Recently, he oversaw the development of all freeway chapters in the 6th Edition of the Highway Capacity Manual (HCM) published in 2016. He is also a contributing author to the new Federal Highway Administration (FHWA) Transportation Systems Simulation Manual (TSSM). Dr. Schroeder has authored or co-authored over 70 peer-reviewed journal articles and conference proceedings. He is a member of the Transportation Research Board (TRB) Committee on Highway Capacity and Quality of Service (current chair of the uninterrupted flow group), the TRB committee on roundabouts, and the TRB Simulation Systems Manual Task Force, and he chairs the Simulation and Capacity Model users Group (SimCap) for the North Carolina Section of the Institute of Transportation Engineers (NCSITE).

Lake Trask, PhD, Transportation Analyst,
Kittelson & Associates, Inc., Wilmington, NC
Dr. Lake Trask is an analyst and programmer for transportation planning and operations projects. He has worked on a number of projects for FHWA and the North Carolina Department of Transportation (NCDOT), where he used his modeling and optimization background to work on algorithm implementation and analysis. Through his project work, he has developed a variety of computational tools, including the FREEVAL engine for the 6th edition of the Highway Capacity Manual, and extensions for reliability analysis, active traffic demand management, and planning-level work zone analysis. He is also working on software solutions implementing work zone intelligent transportation systems (ITS) support for FHWA, and tools to support intersection control evaluation (ICE) policies for several state and federal agencies. His areas of expertise include transportation and mathematical modeling, optimization, and big data analysis, and he has experience with a number of programming languages including Java, JavaScript, Python, PHP, and VBA.
