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 ... -
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 ... -
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 ... -
Error Sensitivity of the Connected Vehicle Approach to Pavement Performance Evaluations
(2016)The international roughness index is the prevalent indicator used to assess and forecast road maintenance needs. The fixed parameters of its simulation model provide the advantage of requiring relatively few traversals ... -
Use of Connected Vehicles to Characterize Ride Quality
(2016)The United States rely on the performance of more than four million miles of roadways to sustain its economic growth and to support the dynamic mobility needs of its growing population. The funding gap to build and ... -
Resolution Agile Remote Sensing for Detection of Hazardous Material Spills
(2016)Traffic carrying flammable, corrosive, poisonous, and radioactive materials continues to increase in proportion with the growth in their production and consumption. The sustained risk of accidental releases of such ... -
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 ... -
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 ... -
Wavelength Sensitivity of a Connected Vehicle Method of Ride Quality Characterizations
(2017)Researchers previously demonstrated that a roughness index called the road impact factor (RIF) is directly proportional to the international roughness index (IRI) when measured under identical conditions. A RIF-transform ... -
Characterizing Pavement Roughness at Non-Uniform Speeds Using Connected Vehicles
(2017)Methods of pavement roughness characterizations using connected vehicles are poised to scale beyond the frequency, span, and affordability of existing methods that require specially instrumented vehicles and skilled ...
