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 ... -
Forecasting the Effects of Autonomous Vehicles on Land Use
(2020)The widespread availability of connected and autonomous vehicles (CAVs) will likely affect social change in terms of how people travel. Traditional methods of travel demand and land use modeling require vast amounts of ... -
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 ... -
Attack Risk Modelling for the San Diego Maritime Facilities
(2020)California is the largest economy among states in the US. More than 40% of the nation's containerized cargo flows through the marine ports of California. Cruise ships also call on four of California's largest ports, with ... -
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 ... -
Literature Review of Socioeconomic and Environmental Impacts of High-Speed Rail in the World
(2021)Countries considering high-speed rail (HSR) developments face enormous challenges because of their high deployment cost, environmental obstacles, political opposition, and their potentially adverse effects on society. ... -
Effects of smartphone sensor variability in road roughness evaluation
(2021)Accelerometers embedded in smartphones have become an alternative means of measuring the roughness of roads. However, the differences in their sensitivity and sampling rates between smartphones could produce measurement ... -
Railroad Accident Analysis Using Extreme Gradient Boosting
(2021)Railroads are critical to the economic health of a nation. Unfortunately, railroads lose hundreds of millions of dollars from accidents each year. Trends reveal that derailments consistently account for more than 70% of ... -
Budgeting the Adoption of Sensors on Connected Trains
(2021)Railroads can save millions of dollars by deploying multi-sensor track scanners on connected trains to detect track and roadbed problems that could cause accidents. However, uncertainties about performance and return-on-investment ... -
Micromobility Station Placement Optimization for a Rural Setting
(2021)Micromobility is an evolving form of transportation modality that uses small human- or electric-powered vehicles to move people short distances. Planners expected that bike sharing, the first form of micromobility, would ... -
Extending Micromobility Deployments: A Concept and Local Case Study
(Springer, 2021)Micromobility is a recent phenomenon that refers to the use of small human- or electric-powered vehicles such as scooters and bikes to travel short distances, and sometimes to connect with other modes of transportation ... -
Applying Unsupervised Machine Learning to Counterterrorism
(2022)To advance the agenda in counterterrorism, this work demonstrates how analysts can combine unsupervised machine learning, exploratory data analysis, and statistical tests to discover features associated with different ... -
Characterizing Ride Quality With a Composite Roughness Index
(2022)There are many important applications that require ride quality characterization. However, the only international standard that specifies a roughness index is not suitable for applications beyond assessing the ride quality ... -
Detecting Sources of Ride Roughness by Ensemble Connected Vehicle Signals
(2022)It is expensive and impractical to scale existing methods of road condition monitoring for more frequent and network-wide coverage. Consequently, defects that increase ride roughness or can cause accidents will go undetected. ... -
An Application of Natural Language Processing to Classify What Terrorists Say They Want
(2022)Knowing what perpetrators want can inform strategies to achieve safe, secure, and sustainable societies. To help advance the body of knowledge in counterterrorism, this research applied natural language processing and ... -
Using Artificial Intelligence to Derive a Public Transit Risk Index
(2022)A terrorist attack on the public transportation system of a city can cripple its economy. Uninformed investments in countermeasures may result in a waste of resources if the risk is negligible. However, risks are difficult ... -
Technology Developments and Impacts of Connected and Autonomous Vehicles: An Overview
(2022)The scientific advancements in the vehicle and infrastructure automation industry are progressively improving nowadays to provide benefits for the end-users in terms of traffic congestion reduction, safety enhancements, ... -
Exploratory Spatial Data Analysis of Traffic Forecasting: A Case Study
(2022)Transportation planning has historically relied on statistical models to analyze travel patterns across space and time. Recently, an urgency has developed in the United States to address outdated policies and approaches ... -
Remediation Ranking of High Crash Fatality Locations Involving Older Drivers in Florida's Rural Counties
(2022)In 2019, Florida's aging road users (65 years or older) accounted for 20% of the population but 37% of all crashes. Florida Department of Transportation has identified aging road users as one of the areas that requires ... -
Vehicle Axle Detection from Under-Sampled Signal through Compressed-Sensing-Based Signal Recovery
(2022)In traffic data collection, sampling design should satisfy the requirements of identifying prominent pulses corresponding to vehicle axle passage. Insufficient measurement leads to signal distortion and attenuation, reducing ...
