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 the driver's behavior and the road's speed selection. Current approaches neglect the importance that design speed has on current users, society, environment, and neighborhood. Due to the limitations of the current design speed selection approach based on American Association of State Highway and Transportation Officials guidelines, Delaware Department of Transportation (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. The research is compiled from the following sources: other state DOTs, other agencies, foreign countries, and current articles on the topic. The ultimate goal of this research is to create an advanced guide for the context sensitive design-speed selection in Delaware. The design speed issue is not purely engineering in nature. It is affected by the local public and deals also with economical and environmental aspects.
