The objectives of the report are to identify and document existing operating speed models developed in different regions of the world. The models are grouped according to roadway type. In addition, authors of the report identify several limitations and deficiencies in the existing operating speed models, and with that, offer suggestions for future work. Practitioner perspectives on the potential use of speed prediction models in road design practice are provided from both a North American and International perspective. The remaining chapters are organized as follows: Chapter 2 describes past studies that were conducted in North America; Chapter 3 presents the current speed modeling practice in several European countries; Chapter 4 covers numerous studies in regions of the world other than North America and Europe; Chapter 5 outlines limitations and deficiencies in existing speed models; and Chapter 6 provides a summary, conclusions, and recommendations for future speed modeling research and implementation.
