Filter by Keyword195 report(s) found with age in the keywords field Stormwater runoff generated in urban areas can increase the risks of flooding and contaminate surface waters. Various contaminants carried by stormwater runoff can negatively affect the water quality of receiving water bodies. Many of the conventional stormwater best management practices are designed... 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... 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... 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... 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... Over the last two decades many researchers have focused on providing new ideas and frameworks that can help improve conventional bridge inspection practices; however, little guidance is provided for implementing these new ideas in practice. This, along with resistance to change and complexity of the... Older adults, people with disabilities, individuals in low-income households, and those living in rural areas can face significant mobility challenges. This study examines travel behavior and mobility of these transportation-disadvantaged groups, including trip rates, miles driven, mode shares, and other... Gravel road safety is a crucial area of road safety since gravel roads represent a substantial proportion of the entire nation's roadway network. Also, gravel roads pose inherent hazards that are otherwise absent in paved roads. Nonetheless, research related to assessing road conditions for county gravel... The ultimate objective of this project was to determine the structural performance of the dynamic message sign (DMS) bonded with chemical adhesive in terms of ultimate strength and fatigue strength. To achieve this objective, this project first investigated the effects of various parameters (i.e., conditioning... This study examines public opinion toward transit during the COVID-19 pandemic, changes in rider behavior, and responses by transit agencies. This was accomplished through two surveys. First, a survey of transit riders and the public was conducted to examine response to the pandemic. It focused on the... |
