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 ... -
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 ... -
A Connected Vehicle Approach for Pavement Roughness Evaluation
(2014)Connected vehicles present an opportunity to monitor pavement condition continuously by analyzing data from vehicle-integrated position sensors and accelerometers. The current practice of characterizing and reporting ... -
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 ... -
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 ... -
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 ... -
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 ...
