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...

Potholes in asphalt pavement surface have detrimental effects on asphalt pavement deterioration and traffic safety. Cost-effective pothole repair methods are needed for highway agencies at all levels. This project aims to identify and evaluate innovative tools, technologies and materials for pothole repair in New Jersey. The pothole repair methods that have...

Bridge decks are prone to various types of cracking due to a combination of factors, including traffic loads, temperature variations, moisture, and chemical exposure. This report tackles the critical issue of bridge deck cracking by systematically dissecting the problem, exploring various crack types, and emphasizing the crucial inspection and categorization of...

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...

Polymer overlays consist of polymer resins and aggregates and are used on bridge decks to extend service life by providing waterproofing and chloride penetration resistance and restoring surface friction. High friction surface treatments (HFSTs) are a specific type of polymer overlay intended to provide long-term skid resistance by using aggregates with...

Traffic control devices, markings, signals, guardrail, computing systems, communications infrastructure, and other permanent and temporary devices will likely each be affected by the operation of connected and autonomous vehicle (CAV) technology. State departments of transportation (DOTs) need to identify gaps in knowledge and skills and prepare for the...

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...

One tool utilized by some departments of transportation (DOTs) to improve safety performance is conducting road safety audits (RSAs), also known as “road safety assessments.” An RSA is a formal evaluation of the safety performance of an existing or future highway segment or intersection performed by an independent, multidisciplinary team. NCHRP...

The existing foundations of a bridge can sometimes be reused. This may occur when a completely new bridge is built but also in bridge or superstructure widening projects. Reuse of existing foundations not only eliminates the costs associated with demolishing and disposing of old foundations, but also reduces the costs of the design and construction of new...

Intersection control evaluation (ICE) is fundamentally a process that provides the framework, steps, and tools and offers decision support for assessing trade-offs between different types of intersection forms and controls. NCHRP Research Report 1087: Guide for Intersection Control Evaluation, from TRB's National Cooperative Highway Research Program,...

This paper authored by CUR Senior Research Fellow, Frank Clayton, addresses why since the mid-2000s housing affordability in Ontario’s largest metropolitan area, Toronto, has deteriorated much more than in the province’s second-largest metropolitan area, Ottawa. There is a growing awareness that an inverse relationship exists between housing...
