Design Speed Selection Recommendations
Current procedure for design speed selection and application has been a concern for many design engineers, researchers, etc for a long period of time. There are two major concerns that must be considered when selecting the design speed: first the fact that the design speed is being exceeded by the majority of drivers, and, secondly, there is a distinct difference between driver's behavior and the road's speed selection. Current approaches neglect the importance the design speed has on current users, society, environment, and neighborhood. Due to limitations of the current design speed selection approach based on AASHTO guidelines, DelDOT design engineers desire alternatives to ensure a better design speed selection process. The scope of this paper is to provide DelDOT design engineers with research that includes the best available information on design speed selection.
