Karst Sinkhole Detecting And Mapping Using Airborne Lidar, Su Zhang, Shirley Baros, Susan Bogus
Karst Sinkhole Detecting And Mapping Using Airborne Lidar, Su Zhang, Shirley Baros, Susan Bogus
Data
Corresponding data set for Tran-SET Project No. 18GTUNM01. Abstract of the final report is stated below for reference:
"The focus of this study is to detect sinkhole hazards using airborne light detection and ranging (LiDAR) data. The premise is sinkholes, particularly those close to transportation infrastructure assets, could cause substantial damages to infrastructure assets, and therefore, being able to accurately and rapidly detect them is essential. However, it is expensive, time-consuming, labor-intensive, and unsafe to survey sinkholes using conventional ground observation methods. This research project was focused on developing accurate and rapid airborne LiDAR-based sinkhole detection and mapping methods, and …

Systematic Approach To Identifying Deeply Buried Archeological Deposits, Anthony L. Layzell, Rolfe D. Mandel, Courtney L. Ziska, John R. Bozell
Systematic Approach To Identifying Deeply Buried Archeological Deposits, Anthony L. Layzell, Rolfe D. Mandel, Courtney L. Ziska, John R. Bozell
Nebraska Department of Transportation: Research Reports
This project is designed to assist cultural resource specialists involved in Nebraska Department of Transportation (NDOT) and the Federal Highway Administration (FHWA) project planning and development. The goal was to develop Geographic Information System (GIS) data layers that spatially delineate different landform-sediment assemblages (LSAs) and depict the associated geologic potential for buried cultural deposits in select watersheds in Nebraska. The Nebraska Buried Sites GIS resource will allow planners and cultural resource specialists to determine whether future project areas are likely to be free of deeply buried sites or whether subsurface exploration is necessary.
Land Suitability Analysis For Emergency Medical Services Posts Along State Highways: A Case Study Of California, Ernest Tufuor, Laurence Rilett, Yunwoo Nam, Antonio Hurtado Beltran
Land Suitability Analysis For Emergency Medical Services Posts Along State Highways: A Case Study Of California, Ernest Tufuor, Laurence Rilett, Yunwoo Nam, Antonio Hurtado Beltran
Department of Civil and Environmental Engineering: Faculty Publications
The response time of Emergency Medical Services (EMS) to road accidents can be the difference between life and death. The California strategic highway safety plan highlight the need to improve the response time and recognizes that: 37% and 8% of the fatal crashes are 30 or more miles away from a trauma center in rural and urban areas respectively.
The paper seeks to: (1) demonstrate the viability of using spatial multi-criteria analysis in road safety management, and (2) provide a good scientific justification in selecting optimal counties for EMS posts. The goal is to propose areas that are close to …
Analysis Of Traffic Collisions In Dublin Using Gis Based System, Jagteshwar Singh, Niamh O' Reilly
Analysis Of Traffic Collisions In Dublin Using Gis Based System, Jagteshwar Singh, Niamh O' Reilly
Conference papers
This study aims to analyse traffic collisions in the Greater Dublin Region between the period 2006-2012, using GIS to identify hotspots and examine the relationship between collisions and a range of contributory factors including vehicular speeds, traffic volume, road curvature, road category and distance from intersection that could enable prediction of traffic collisions. To this end, Road Safety Authority (RSA) collision data for Dublin Region geocoded as point events, road profiles, traffic flow characteristics on which these occur are spatially merged using ArcGIS and FME software to establish if a significant relationship exists between collision frequencies on road links and …
Snow And Ice Removal Route Optimization In Kentucky, Benjamin L. Blandford, Erin Lammers-Staats, Eric R. Green
Snow And Ice Removal Route Optimization In Kentucky, Benjamin L. Blandford, Erin Lammers-Staats, Eric R. Green
Kentucky Transportation Center Research Report
Each year the Kentucky Transportation Cabinet (KYTC) spends $40-$80 million removing snow and ice from the state’s roadways. Snow and ice removal are accomplished through a system of snow and ice removal routes that are designed to account for location and the attributes of trucks, facilities, materials, and roadways. To identify strategies that will improve and optimize KYTC’s snow and ice removal operations, Kentucky Transportation Center (KTC) researchers used ArcGIS and its Network Analyst extension to study the performance of the Cabinet’s current routing procedures. Building from this investigation, researchers developed optimized snowplow routings for four counties located in KYTC …
An Evaluation Of The Safety Of The Cycling In Dublin City For Dit Students, Niamh O' Reilly
An Evaluation Of The Safety Of The Cycling In Dublin City For Dit Students, Niamh O' Reilly
Articles
Cycling as a mode of transport offers many benefits including a cheap, cost effective, healthy, fast, mainly congestion free and environmentally friendly means of getting to and from places of employment and education. Given the central location of Technological University Dublin campus buildings this would seem an ideal option for its third level students, but on the contrary, a DIT online travel survey conducted in March 2014 found that only 7% of students chose cycling as their primary mode of transport. Concerns about cyclist safety were a major factor cited by students who chose alternative modes of transport. Based on …
A Multi-Criteria Gis-Based Route Selection Tool For Hazardous Material Transport: Consideration Of Environmental Consequence, Traffic Congestions And Costs, Bahareh Inanloo
FIU Electronic Theses and Dissertations
Hazardous materials are substances that, if not regulated, can pose a threat to human populations and their environmental health, safety or property when transported in commerce. About 1.5 million tons of hazardous material shipments are transported by truck in the US annually, with a steady increase of approximately 5% per year.
The objective of this study was to develop a routing tool for hazardous material transport in order to facilitate reduced environmental impacts and less transportation difficulties, yet would also find paths that were still compelling for the shipping carriers as a matter of trucking cost. The study started with …
Integrated Freight Network Model: A Gis-Based Platform For Transportation Analyses, Ted H. Grossardt, John Ripy, Benjamin L. Blandford, Michael Shouse
Integrated Freight Network Model: A Gis-Based Platform For Transportation Analyses, Ted H. Grossardt, John Ripy, Benjamin L. Blandford, Michael Shouse
Kentucky Transportation Center Research Report
The models currently used to examine the behavior transportation systems are usually modespecific. That is, they focus on a single mode (i.e. railways, highways, or waterways). The lack of integration limits the usefulness of models to analyze the intermodal movement of freight. This project developed a GIS-based model of the three primary surface modes as well as intermodal connections. The resulting Integrated Freight Network Model (IFNM) accommodates highly detailed about shipping costs, transfer costs, traffic volumes (including non-freight auto traffic), and network interconnectivity properties. As a proof of concept, the research team conducted an exploratory analysis that asked what the …

The study reviewed the current practices of data integration by other organizations that face the similar challenges as KyTC. In addition, a review was conducted of the …
Development Of A Traffic Sign Inventory System (Sign Click), Eric R. Green
Development Of A Traffic Sign Inventory System (Sign Click), Eric R. Green
Kentucky Transportation Center Research Report
A system is not currently in place to inventory traffic signs in Kentucky. A sign inventory database would be beneficial for those responsible for maintenance and management of signs. The overall safety provided the driving public could benefit from an efficient inventory system that increases an agency’s knowledge of existing signs. In addition, a comprehensive inventory and mechanisms for updating the inventory could reduce the potential for liability associated with outdated, inappropriately placed, or missing signs. Software is available for this kind of inventory; however it can be expensive and would lack the specific features that could be developed in-house. …
