2010 Highway Capacity Manual Workshop

October 28, 2009

On October 28, 2009, a workshop discussing the 2010 Highway Capacity Manual (HCM) was held at the Portland office of Kittelson & Associates, Inc. (KAI). The interactive workshop was presented by Mark Vandehey and Susan Wright of KAI. They described the development of the manual and potential applications for new methods at statewide, regional, and project levels. A bit of additional information on the upcoming HCM 2010 and the presenters can be found below:

2010 Highway Capacity Manual: KAI is the lead contractor for the development of the 2010 Highway Capacity Manual, responsible for incorporating the results of more than $5 million in funded research into one of the profession’s primary reference documents. The 2010 manual has been reorganized into four volumes that present concepts, methodologies, and supplemental details at the different levels of information required by the many HCM audiences (e.g., junior analysts, experienced professionals, decision-makers, researchers, and software developers). Another significant enhancement to the HCM is a multimodal approach throughout the manual. Rather than having separate, stand-alone chapters for pedestrians, bicycles, and transit, information relevant to those modes is presented side-by-side with material for the automobile mode wherever feasible. KAI also worked on several other projects that developed content for the 2010 HCM, including the new chapter on roundabouts, developing the transit component of the new multimodal level-of-service method for urban streets, and contributing to the new urban streets speed-estimation procedure. The presentation below provides an overview of the many significant improvements that will be included in the 2010 HCM.

Mark Vandehey is the Chief Operating Officer for KAI and the Principal Investigator for the research project that will produce the 2010 HCM. The research is being conducted under a contract with the National Cooperative Highway Research Program (NCHRP). Mark has been an active member of the Transportation Research Board’s Committee on Highway Capacity and Quality of Service for nearly 20 years and has been a key contributor on several national research projects in the area of highway capacity and traffic engineering.

Susie Wright has been with KAI for nearly nine years and currently coordinates the firm's Portland Planning Group. She has participated in a wide variety of transportation planning and traffic operations projects, with experience ranging from transportation system plans and interchange area management plans to signal timing implementation, downtown parking plans and development code updates. Susan has a B.S. in Civil Engineering from OSU, is a registered Professional Engineer, and has served on the Board for the Portland Chapter of the Women’s Transportation Seminar for the past four years.
