A Study On Effect Of Information From Navigation System On Driving Behavior, Mio Suzuki, Shota Moriya

Kentucky Transportation Center Presentations

In recent years, navigation services using smartphone applications have become common, and while the number of users is increasing, accidents and violations have begun to occur due to drivers being so focused on obtaining information that they cannot see their surroundings or the information itself is incorrect. Therefore, this study focuses on the fact that stress on drivers caused by such guidance can also be a cause of accidents, and aims to understand the understandability of information and driving behavior of navigation systems and stress by using a driving simulator. From the questionnaire survey by the users, it was found …

An Exploratory Analysis Of Fatal Vehicle Crashes In Urban And Rural Kansas In Relation To Identified Golder Hour Gaps In Hospital Coverage, Mason W. Lipford, Grace N. Whisler Lipford, Gregory L. Newmark, Eric J. Fitzsimmons

Kentucky Transportation Center Presentations

The state of Kansas is a relatively rural state with a majority of highway/interstate miles through farmland and low populated areas. These rural areas can be hot spots for crashes to occur and the lack of hospitals and emergency response nearby can make these types of crashes turn deadly. Few studies have been done on this topic especially for the state of Kansas. As the Department of Transportation is pushing to the “Drive to Zero” goal, pinpointing the harmful factors to indicate where improvements are needed to reduce the number, and severity of crashes is an important first step. Using …

Analyses And Reconstructions Of Crash Scenarios For Class 8, Long-Haul Trucks, Monish Dev Sudhakhar, Rohan Khaire, Jeffrey Wishart, Yan Chen

Kentucky Transportation Center Presentations

Knowledge and analysis of crash scenarios from naturalistic driving data can provide insight into the causes of crashes and thus motivate or benefit the future design of automated driving systems (ADSs). The circumstances commonly resulting in crashes for human-driven, light-duty vehicles were previously compiled into the 37 pre-crash scenarios by NHTSA [1]. However, crash analyses and reconstructions for Class 8 long-haul trucks have not yet been explored in the literature. The Crash Investigation Sampling System (CISS) database has been used as the crash data source for compiling a dataset containing details on a nationally representative sample of thousands of heavy-duty …

Geodatabase And Automation Code Used For Past And Real-Time Dynamic Landslide Hazard Maps In Eastern Kentucky, Nathaniel O'Leary, L. Sebastian Bryson, Jason M. Dortch

Earth and Environmental Sciences Research Data

We developed spatiotemporal landslide hazard maps (LHMs) using soil, hydrologic, and geomorphic parameters from the subaerial infinite slope factor of safety (FS) equation under unsaturated conditions. Soil properties were sourced from the NRCS WSS, while geomorphic variables were derived from a 1.5 m LiDAR-based DEM and ArcGIS Online. Soil moisture from Hydrus-1D, driven by precipitation and evapotranspiration (ET) data from Irrigation Manager, introduced temporal variability. Validation against known landslide sites demonstrated FS accuracy both spatially and temporally, despite some false positives. To reduce false positives and enhance slope stability representation, novel depth-to-bedrock (DTB) and soil root cohesion maps were incorporated …

The significance of crowdsourced geospatial data in the realm of urban sciences is now widely acknowledged. A diverse array of novel data sources has been increasingly gaining prominence. These include, but are not limited to, social media platforms, street …

A Multi-Life Cycle Assessment Of External Wall Insulation Strategies In An Irish Domestic Retrofit, Sara Carrigan, Patrick Daly, Alberta Congeduti

Articles

European Union (EU) policy and initiatives are driving both building renovation and the uptake of low-embodied carbon and circular design in the construction sector. The European Performance of Buildings Directive (EPBD) recast (2021) introduces global warming potential (GWP) methodology, and the future state will likely be embodied carbon targets for which life cycle assessment (LCA) of buildings will be required. External wall insulation (EWI) will have an important role to play in meeting targets. In this context, this paper compares the carbon emission payoff of three alternative EWI strategies that address conventional, low-carbon and circular solutions to EWI respectively, in …

Classification Of Sow Postures Using Convolutional Neural Network And Depth Images, Md Towfiqur Rahman, Tami M. Brown-Brandl, Gary A. Rohrer, Sudhendu R. Sharma, Yeyin Shi

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The United States swine industry reports an average preweaning mortality of approximately 16% where approximately 6% of them are attributed to piglets overlayed by sows. Detecting postural transitions and estimating sows’ time budgets for different postures are valuable information for breeders and engineering design of farrowing facilities to eventually reduce piglet death. Computer vision tools can help monitor changes in animal posture accurately and efficiently. To create a more robust system and eliminate varying lighting issues within a day including daytime/ nighttime differences, there is an advantage to using depth cameras over digital cameras. In this study, a computer vision …

Analysis Of Delta In-Out For Irish Natural Gas Distribution Network, Utkarsha Chavan, Anthony Reynolds, Michael Carr, L. Walsh

Articles

This article investigates the issue of Unaccounted for Gas (UAG) in the natural gas distribution network of Ireland, focusing on the DeltaIO (i.e. the difference between the gas entering and leaving the network). The study applies the DeltaIO methodology developed for Italian distribution networks to Gas Networks Ireland (GNI), the sole Distribution System Operator (DSO) in Ireland. The analysis covers the period from 2013 to 2019 and provides insights into the magnitude and trends of UAG in the Irish context. The results show that GNI's DeltaIO ranges from 0.93% to 1.57%, with an average of 1.15%. Comparisons with large Italian …

Unintended Consequences: Changes In Driver Behavior Associated With The Adoption Of Advanced Driver Assistance Systems, Nischal Gupta, Peter T. Savolainen

Kentucky Transportation Center Presentations

Advanced driver assistance systems (ADAS) are a disruptive precursor to fully autonomous vehicles (AVs), which will have far-reaching impacts on the nature of travel. With various ADAS features becoming increasingly common in vehicles, some unintended changes in driving behavior are expected including engaging in more risk-taking behavior while driving. To that end, the present study utilizes survey-based data of 1,000 Michigan adults and investigates the likelihood of drivers engaging in three different driving behaviors- cell phone use, consumption of alcohol, and tailgating when driving a vehicle with collision alert systems by means of multivariate ordered probit regression analysis. Results showed …

A 3-Step, Open-Data, Ride-Hailing Ridership Model With Pricing Applications, Richard A. Mucci

Theses and Dissertations--Civil Engineering

Researchers and practitioners studied the effects ride-hailing had in cities before the covid-19 pandemic. Previous research found ride-hailing to produce negative externalities, such as reducing transit ridership and increasing congestion in various cities. Since the pandemic, ride-hailing ridership has nearly recovered to pre-pandemic levels in Chicago. Ride-hailing ridership has grown steadily since the pandemic while a rider’s willingness to share their trip stagnated. Ride-hailing ridership nearly recovering to pre-covid levels in Chicago suggests that transportation planners, and policy makers, will need to continue assessing the impacts ride-hailing trips have in their cities.

Pickup and drop off locations in the Chicago …

Identifying The Job Characteristics Affecting Construction Firm Employee Turnover Intention, Seog Jae Choi

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Researchers have proved that employees who have the intention to quit the organization, called turnover intention, have decreased productivity and may not fulfill their duties properly. The turnover intention has a negative relationship with the quality of core job characteristics of the organization. As the construction industry has distinctive characteristics compared to other industries, the job characteristics that influence turnover intention need to be explored separately. This study identifies job characteristics of the construction industry that can affect turnover intention. Through the literature review, autonomy, task identity, required skill variety, task significance, justification in assigning work location, and job security …
