Modeling Operating Speed: Synthesis Report. Chapter 5: Deficiencies in Existing Speed Models

This chapter describes the main limitations and deficiencies identified in the existing speed profile models. The following topics are addressed: issues with data collection; unrealistic assumptions of driver behavior; difficulties in estimating speed changes between geometric elements; lack of uniformity across models; consideration of only passenger cars; limitations of linear regression; and limited applicability of models.
