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 ...
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 ...
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 ...
Context Sensitive Solution: A Case Study of Northwest Highway White Rock Lake, Dallas in Texas
(2015)
Loop 12 is the first ring around the city of Dallas. The project is a three-quarter mile section of Loop 12 on Northwest Highway. The project section of Northwest Highway is a set of six bridges that cross a 100-year ...
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 ...
Hyperspectral Range Imaging for Transportation Systems Evaluation
(2016)
Transportation agencies expend significant resources to inspect critical infrastructure such as roadways, railways, and
pipelines. Regular inspections identify important defects and generate data to forecast maintenance ...
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 ...
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 ...
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 ...
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 ...
