Jake is a Regional Traffic and Safety Engineer for the Colorado Department of Transportation and has over 20 years of experience in highway and traffic engineering. He is a member of the Transportation Research Board (TRB) and served on numerous research study panels at the National Cooperative Highway Research Program (NCHRP). Dr. Kononov is an author of a number of research papers on road safety published by the TRB, Swedish National Road and Transport Institute (VTI), German Road Research Institute (BAST), Italian Society oh Highway Infrastructure (SIIV) and Public Works Magazine. For the last 14 years he is an adjunct professor at the School of Civil Engineering at the University of Colorado in Denver. He teaches undergraduate and graduate courses in transportation engineering and PE preparatory seminars. Jake is a member of the Colorado/Wyoming ITE Chapter.

Bryan Allery, P.E. has 18 years of experience in transportation engineering, seven years at Caltrans and 12 years at CDOT. Bryan is currently a manager of safety programs at CDOT, together with Dr. Kononov he has coauthored a number of research papers on road safety published by the TRB.

Topic Description:  Roadway Safety

It is important to make clear at the outset what 'Road Safety' means. Of two alternative highway designs connecting points A and B and serving the same traffic, that highway design which is likely to have fewer and less severe accidents is the safer one. Thus, the safety of a road is measured by the frequency and severity of accidents expected to occur on it. If so, safety of a road is always a matter of degree. A road can be safer or less safe, but how much safety is enough? How much safety for how much money can we reasonably expect? Are roads designed to meet current standards as safe as they can be or are they as safe as they should be? These and many other questions related to explicit consideration of safety in planning and design of highways will be explored during this presentation presentation.

The presentation will offer a methodological foundation and an analytical framework for the explicit consideration of safety in planning and design of highways. It provides a practical approach to solving a complex problem of road safety by integrating elements of geometric design, traffic operations, statistics and risk analysis.
