The South Dakota Department of Transportation (SDDOT) currently has a Finite-Element Surface-Water Modeling System for Two-Dimensional Flow (FESWMS-2DH) and Research Management Associates 2 (RMA2) Both programs have the capability to model two-dimensional (2D) flow around structures. The department must...
A research study was conducted by South Dakota State University in cooperation with the South Dakota Department of Transportation (SDDOT) to assess applicability of the American Association of State Highway and Transportation Officials (AASHTO) design calculations for the dynamic ice loads on bridge...
Redundancy is vital for transportation networks to provide utility to users during disastrous events. In this project, we develop two network-based measures for systematically characterizing the redundancy of transportation networks: travel alternative diversity and network spare capacity. The travel...
Providing acute medical care outside of the hospital, Emergency Medical Services (EMS) is crucial in rural environments where hospitals are not close by and are difficult to access. This study used the National EMS Information System (NEMSIS) South Dakota data to exemplify the establishment of data-driven...
This research presents network analysis tools for estimating bicycle demand and bicycle volumes on a transportation network. There are three main procedures used in the development of the network analysis tools: an initial bicycle origin-destination (O-D) demand generation procedure, a bicycle traffic...
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...
Improved emergency medical services (EMS) will impact traffic safety and public health in rural communities. Better planned, designed, and operated roadway networks that connect hospitals with communities in need will enhance EMS performance. To provide safe, timely and quality services, it is necessary...
This report details the outcomes of shear spiking two open-deck, timber trestle railroad bridges and examining the effectiveness under applied loading. The bridges were made available to the researchers by the Union Pacific Railroad and were located in their Southern Region. The first site was located...
In a previous related study conducted by the University of Wyoming (Phase I), fatigue cracking of traffic signal poles was determined to be related to the average wind speed (Price 2009). However, high-mast data did not indicate the same direct average wind speed fatigue cracking relationship behavior....
