Assessing Lifecycle and Human Costs of Bus Operator Workstation Design and Components

Designing extended sections of highway based on the road design speed is relatively straightforward. However, when applied to interchange ramps where high-speed facilities meet low-speed facilities and drivers are expected to accelerate or decelerate o…

Design speed is used to determine all pertinent highway features to obtain a balanced design. Over an extended length of highway, it is desirable to select a uniform design speed. The TRB National Cooperative Highway Research Program’s NCHRP Web-Only D…

Per- and polyfluoroalkyl substances (PFAS) are a class of more than 6,000 contaminants of emerging concern that can harm both ecosystems and human health. These anthropogenic compounds contain carbon–fluorine bonds that make them stable and persistent …
