Railroad Track Condition Monitoring Using Inertial Sensors and Digital Signal Processing: A Review
(2018)Inertial sensors such as accelerometers and gyroscopes have been widely used since the early 1990s to monitor the condition of transportation assets. Recent improvements in their performance, a reduction in cost, and sensor ... -
Road Profile Reconstruction Using Connected Vehicle Responses and Wavelet Analysis
(2018)Practitioners analyze the elevation profile of a roadway to detect localized defects and to produce the international roughness index. The prevailing method of measuring road profiles uses a specially instrumented vehicle ... -
Signal Filter Cut-off Frequency Determination to Enhance the Accuracy of Rail Track Irregularity Detection and Localization
(2019)A continuous condition monitoring system to detect and localize railroad track irregularities is achievable with inertial sensors onboard revenue service trains. However, the inaccurate geospatial position estimates of GPS ... -
Enhancement of Signals from Connected Vehicles to Detect Roadway and Railway Anomalies
(2019)Frequent network-wide monitoring of the condition of roadways and railways prevent fatalities, injuries, and financial losses. Even so, agencies cannot afford to inspect vast transportation networks using present methods. ... -
Road Roughness Evaluation Using In-Pavement Strain Sensors
(2015)The international roughness index (IRI) is a characterization of road roughness or ride quality that transportation agencies most often report. The prevalent method of acquiring IRI data requires instrumented vehicles and ... -
Accuracy Enhancement of Anomaly Localization with Participatory Sensing Vehicles
(2020)Transportation agencies cannot afford to scale existing methods of roadway and railway condition monitoring to more frequently detect, localize, and fix anomalies throughout networks. Consequently, anomalies such as potholes ... -
Policy Implications of Truck Platooning and Electrification
(2020)Trucks in North America account for more than 23% of the transportation sector’s greenhouse gas emissions. Truck platooning and truck electrification are potential technologies for reducing emissions and operating cost. ... -
A Fuzzy Delphi Analytic Hierarchy Model to Rank Factors Influencing Public Transit Mode Choice: A Case Study
(2020)This study applied a decision-based model with uncertainty to identify factors in mode choice and to rank their influence in attracting riders to available public transit modes in the city of Tehran. The model integrates ... -
Closed Form Models to Assess Railroad Technology Investments
(2020)Class I railroads in North America collectively invested $11.2 billion to comply with a federal mandate to deploy positive train control. This amount dwarfs the potential savings from accidents the technology could prevent. ... -
A Cognitive Framework to Plan for the Future of Transportation
(2020)Automated, connected, electrified, and shared mobility will be cornerstones of the transportation future. Research to quantify the potential benefits and drawbacks of practice, and to identify barriers to adoption is the ... -
Weigh-In-Motion System in Flexible Pavements Using Fiber Bragg Grating Sensors Part A: Concept
(2019)Weight data of vehicles play an important role in traffic planning, weight enforcement, and pavement condition assessment. In this paper, a weigh-in-motion (WIM) system that functions at both low-speeds and high-speeds in ... -
Calibration of Smartphone Sensors to Evaluate the Ride Quality of Paved and Unpaved Roads
(2020)Transportation agencies report that millions of crashes are caused by poor road conditions every year, which makes the localization of roadway anomalies extremely important. Common methods of road condition evaluation ... -
Review of Usage of Real-World Connected Vehicle Data
(2020)GPS loggers and cameras aboard connected vehicles can produce vast amounts of data. Analysts can mine such data to decipher patterns in vehicle trajectories and driver–vehicle interactions. Ability to process such large-scale ... -
Model Contrast of Autonomous Vehicle Impacts on Traffic
(2020)The adoption of connected and autonomous vehicles (CAVs) is in its infancy. Therefore, very little is known about their potential impacts on traffic. Meanwhile, researchers and market analysts predict a wide range of ... -

(North Dakota State University. Libraries, 9/10/2020)This event was hosted by NDSU Libraries. The presentation was pre-recorded and then shared on NDSU Libraries’ Facebook page. -
ITS Technology Usage and Feasibility in Small Urban and Rural Transit
(North Dakota State University, 2020-04)Intelligent transportation system (ITS) applications have been widely applied to the highway system, and are being used by an increasing number of small urban and rural transit systems throughout the United States. The ... -
2015 NDSU Bean Breeding Program Genotyping Snapshot
The dataset consists of genotyping and common bacterial blight phenotyping information from genotypes within the NDSU Dry Bean Breeding Program. The Middle American data set consists of 713 genotypes and the Andean dataset ... -
Agricultural and Biosystems Engineering Capstone Course Evolution at North Dakota State University
(American Society of Agricultural and Biological EngineersAmerican Society of Agricultural EngineersNorth Dakota State University, 2005)The approach to the department's capstone design course has changed considerably since the 1960s. The general evolution of the course has proceeded from extended laboratory exercises to individuals working on self-defined ... -
