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 ... -
Mining Connected Vehicle Data for Beneficial Patterns in Dubai Taxi Operations
(2018)On-demand shared mobility services such as Uber and micro-transit are steadily penetrating the worldwide market for traditional dispatched taxi services. Hence, taxi companies are seeking ways to compete. This study mined ... -
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 ... -
A Participatory Sensing Approach to Characterize Ride Quality
(2014)Rough roads increase vehicle operation and road maintenance costs. Consequently, transportation agencies spend a significant portion of their budgets on ride-quality characterization to forecast maintenance needs. The ... -
Pavement Performance Evaluations Using Connected Vehicles
(2016)The ability of any nation to support economic growth and commerce relies on their capacity to preserve and to sustain the performance of pavement assets. The ever-widening funding gap to maintain pavements challenges the ... -
Performance of Hyperspectral Imaging with Drone Swarms
(2018)The ongoing proliferation and diversification of remote sensing platforms offers greater flexibility to select from a range of hyperspectral imagers as payloads. The emergence of low-cost unmanned aircraft systems (drones) ... -
Perspectives on Securing the Multimodal Transportation System
(2022)The vast, open, and interconnected characteristics of the transportation system make it a prime target for terrorists and hackers. However, there are no standard measures of transport system vulnerability to physical or ... -
Perspectives on Using Connected Vehicles for Transportation Infrastructure Condition Monitoring
(2022)The condition of surface transportation infrastructure directly affects the economic health of a nation. However, it is difficult to justify the large sums of money needed to extend current methods to monitor all the ... -
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. ... -
Precision Bounds of Pavement Deterioration Forecasts from Connected Vehicles
(2014)Transportation agencies rely on models to predict when pavements will deteriorate to a condition or ride-index threshold that triggers maintenance actions. The accuracy and precision of such forecasts are directly proportional ... -
Precision Bounds of Pavement Distress Localization with Connected Vehicle Sensors
(2014)Continuous, network-wide monitoring of pavement performance will significantly reduce risks and provide an adequate volume of timely data to enable accurate maintenance forecasting. Unfortunately, transportation agencies ... -
Precision Enhancement of Pavement Roughness Localization with Connected Vehicles
(2016)Transportation agencies rely on the accurate localization and reporting of roadway anomalies that could pose serious hazards to the traveling public. However, the cost and technical limitations of present methods ... -
Predicting Advanced Air Mobility Adoption by Machine Learning
(2023)Advanced air mobility (AAM) is a sustainable aviation initiative to deliver cargo and passengers in urban and regional locations by electrified drones. The widespread expectation is that AAM adoption worldwide will help ... -
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 ... -
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 ... -
Ranking Risk Factors in Financial Losses From Railroad Incidents: A Machine Learning Approach
(2023)The reported financial losses from railroad accidents since 2009 have been more than US$4.11 billion dollars. This considerable loss is a major concern for the industry, society, and the government. Therefore, identifying ... -
Rapid Hyperspectral Image Classification to Enable Autonomous Search Systems
(2016)The emergence of lightweight full-frame hyperspectral cameras is destined to enable autonomous search vehicles in the air, on the ground, and in water. Self-contained and long-endurance systems will yield important new ... -
Reducing Risks by Transporting Dangerous Cargo in Drones
(2022)The transportation of dangerous goods by truck or railway multiplies the risk of harm to people and the environment when accidents occur. Many manufacturers are developing autonomous drones that can fly heavy cargo and ... -
Relating Subjective Ride Quality Ratings to Objective Measures
(2022)Agencies have long used subjective roughness ratings from panels of users to inform policy development on road maintenance strategies. The commoditization of electronics motivated the development of more objective, automated, ... -
