Transportation access management is defined as systematic control of the design, spacing, operation, and locations of street connections, interchanges, driveways, and median openings on the roadway with the purpose of providing vehicle access while preserving the efficiency and safety of the entire transportation...

 

Local governments have an immediate need for low life-cycle cost bridge replacement alternatives. Knowledge of available alternatives and construction planning processes hold potential for South Dakota local governments to replace more structurally deficient local bridges with limited funds. Through...

 

A study was conducted to develop recommendations for short span concrete structure type selection based on analyses of existing structure costs and performance data from South Dakota roadway systems. Through a combination of data sources, including the PONTIS database, local owner and inspector surveys...

 

To facilitate the implementation of Mechanistic-Empirical Pavement Design Guide in Wyoming, this research investigated the relationships between subgrade resilient modulus (Mr) and the dynamic cone penetration and the standard penetration test results, selected three best subgrade Mr predictive models...

 

Mitigating traffic congestion and reducing transportation emissions are among the leading goals of most local, regional, national, and international agencies. Several guidelines rely primarily on strategies that support the following: 1) mixed land-use and transit-oriented developments, 2) multimodal...

 

An experimental research study was conducted to develop optimized concrete mixtures for jointed plain concrete (JPC) pavements and field evaluation of newly constructed JPC pavement sections along South Dakota highways. Using South Dakota aggregates, different concrete mixtures were assessed for optimum...

 

Concrete infrastructures in cold areas such as South Dakota tend to experience early deterioration that is mostly triggered by steel corrosion. The corrosion is initiated by chloride penetration through cracks in the concrete. Fiber reinforced concrete (FRC) is known to be a good alternative to conventional...

 

Roadside barriers are the primary structural safety devices on surface roads. They can be made from any material as long as they can absorb the energy involved in an impact scenario. One material that has that potential is Ipe, which is a hardwood material that has relatively high strength compared with...

 

While high income represents one path to resilience, our results suggest higher resilience in locations with proximity to high levels of employment, with more compact and connected street networks that facilitate walking and bicycling, and/or with better transit infrastructure. Current transit usage...

 

To date, BIM (Building Information Modeling) is not widely utilized in infrastructure asset management. Benefits achieved through implementation in vertical construction, however, suggest that BIM represents significant opportunity for gains in process, material, and economic efficiency throughout infrastructure...
