A before-and-after study of speed changes in one Minnesota city shows that changing posted speed limits may not—at least initially—cause drivers to slow down. This new finding is important for Minnesota’s state and local transportation agencies as they continuously search for the most effective ways to reduce unsafe speeds and meet their...

As vehicle technology advances, Traffic Incident Management (TIM) and emergency responders (ERs) are facing unprecedented circumstances in knowing how to engage with and respond to connected, automated vehicles (CAV). Uncertainty is complicated by limited communications and information exchanged between CAV developers, TIM, and ERs. NCHRP Research Report...

Many state departments of transportation (DOTs) are undergoing organizational changes to address climate change. Changes range from hiring additional staff to creating new offices within the organizational structure of the agency. State requirements in the form of legislation, executive orders, and climate action plans are primary drivers for state DOT...

Surficial slope failures in highway fill embankments are shallow landslides that occur within the embankment fill, usually affecting only a portion of the slope’s height. These failures tend to occur after a vulnerable embankment slope is subjected to a triggering event. An embankment’s failure susceptibility generally depends on factors such as...
