Hyperspectral Imaging Utility for Transportation Systems
(2015)
The global transportation system is massive, open, and dynamic. Existing performance and condition assessments of the
complex interacting networks of roadways, bridges, railroads, pipelines, waterways, airways, and ...
Rolling-Stock Automatic In-Situ Line Deterioration and Operating Condition Sensing
(2013)
Track and equipment failures dominate railroad accident causes. Railroads must visually
inspect most tracks in service as often as twice weekly to comply with the Federal Track Safety Standards.
They augment visual ...
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 ...
Strategic Global Logistics Management for Sourcing Road Oil in the U.S.
(2017)
The demand for asphalt and road oil heavily leverages local supply because the product is a hot binder of aggregates that form the final mix needed to pave roads. This paper discusses the supply chain characteristics of ...
Inertial Sensor Sample Rate Selection for Ride Quality Measures
(2014)
The Road Impact Factor is a measure of ride-quality. It is derived from the average inertial
response of vehicles to road roughness. Unlike the International Roughness Index, the most
common measure, the road impact ...
Campus Parking Supply Impacts on Transportation Mode-Choice
(2014)
Parking demand is a significant land-use problem in campus planning. The parking
policies of universities and large corporations with facilities located in small urban areas
shape the character of their campuses. These ...
Accuracy Enhancement of Roadway Anomaly Localization Using Connected Vehicles
(2016)
The timely identification and localization of roadway anomalies that pose hazards to
the traveling public is currently a critical but very expensive task. Hence,
transportation agencies are evaluating emerging alternatives ...
Vibration Energy Harvesting for Disaster Asset Monitoring Using Active RFID Tags
(2010)
This paper highlights the importance of energy
harvesting in high-value asset monitoring applications involving
use of active RFID tags. The paper begins by highlighting
advantages of active tags including improved range ...
Sourcing Strategy for Asphalt Production Feedstock Considering Multimodal Transport Options
(2016)
This paper examines the logistics and distribution channels for importing heavy crude oil, which
is a source of bitumen. The study conducts a sensitivity analysis to assess the suitability of
existing or new distillery ...
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 ...
