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