Urban traffic networks consisting of partially blocked roads often need to remain open to traffic before, during, and after disasters because of their vital roles to hazard preparation, emergency response, and recovery of urban communities. Conducting effective traffic planning of disrupted transportation...
An efficient and timely rescue of injured people by emergency medical services (EMS) is essential to saving as many lives as possible following disasters. Disrupted traffic networks due to the failures of transportation infrastructure (e.g., bridges) following major disasters like earthquakes affect...
Green stormwater infrastructure (GSI) is increasingly used to reduce stormwater input to the subsurface stormwater network. This work investigated how GSI interacts with surface runoff and stormwater structures to affect the spatial extent and distribution of roadway flooding and subsequent effects on...
Three bridge sites in South Dakota with streamflow records ranging from 50 to 67 years were selected to compute the histories of pier or contraction scour using the Scour Rates In COhesive Soils (SRICOS) method. Scour depths were computed using a range of soil erosion functions representative of cohesive...
In 2020, the COVID-19 pandemic created various economic, environmental, and social challenges, and public transportation was one of the primary and necessary services that were disrupted by the pandemic. Ridership demand decreased dramatically due to lockdown, many people working from home, and people...
The current pandemic has affected the lives of all Americans. Rural communities are particularly vulnerable because of a lack of mobility services and the great distances individuals must travel for healthcare and other needs. Nearly five million veterans live in rural communities, representing 57% of...
Federal Motor Carrier Safety Administration (FMCSA) provides grant funding to states wishing to deploy projects which fit within the scope of the Innovative Technology Deployment (ITD) program. FMCSA recognizes two levels of ITD deployment. Core ITD requires states to implement a basic set of capabilities...
The Rural Transit Fact Book serves as a national resource for statistics and information on rural transit in America. This publication includes rural demographic and travel behavior data as well as financial and operating statistics for agencies receiving section 5311 funding. In addition to national-level...
This report presents a comparative experimental study on the axial behavior of concrete subjected to alkali-silica reaction (ASR) with and without confinement by carbon-fiber reinforced polymer (CFRP) sheets. A total of 120 cylinders are cast using two types of coarse aggregates to represent variable...
Autonomous Vehicles (AVs) have the potential to offer benefits and flexibility in travel, which can lead to significant reductions in the generalized travel cost and possibly, more demand. The combination of the AV technology with Mobility as a Service (MaaS) creates a new disruptive transportation mode...
