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 ...
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 ...
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 ...
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 ...
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. ...
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 ...
