Identifying Distraction: Kinematic Detection of Off-Road Eye Glances
(National Surface Transportation Safety Center for Excellence, 2015-10-08)
Visual attention is a key component of the driving task. Identifying times when the driver is not looking toward the forward views has been shown to be a successful indicator of distracted driving (Olson, Hanowski, Hickman, ...
A Fair Division Approach to Performance-based Cross-Asset Resource Allocation
Resource allocation mechanisms have become a major issue for transportation agencies in the United States and around the world. In order to meet budgetary restrictions resulting from reductions in funding, transportation ...
Long-Term Pavement Performance Automated Faulting Measurement
This study focused on identifying transverse joint locations on jointed plain concrete pavements (JPCP) using an automated joint detection algorithm and computing faulting at these locations using Long-Term Pavement ...
The Use of Measured Pavement Performance Indicators and Traffic in Determining Optimum Maintenance Actions for a toll road in South Africa and Comparison with HDM-4 Predictions
The Bela-Bela/Polokwane toll road on National Route 1 was the first Build, Operate and Transfer (BOT) type contract in South Africa. Extensive data on the pavement performance and traffic loading was collected as part of ...
Luminance metrics for roadway lighting
(Virginia Tech. Virginia Tech Transportation Institute, 2011-03-25)
The focus of the current study is the comparison of multiple contrast metrics... The images of pedestrians from a previous nighttime research study were used for analysis. The pedestrians were clothed in both denim and ...
Prequalification Criteria for Pavement Inspectors
The Orange County Transportation Authority (OCTA) conducts periodic pre-qualification studies to evaluate the proficiency of pavement inspectors in performing pavement distress surveys per ASTM Standard D6433. The results ...
Using Naturalistic Driving Data to Examine Age and Gender Differences on Seat Belt Use
Teens and young drivers are often reported as one driver group that has significantly lower seatbelt use rates than other age groups. Objective This study was designed to address the questions of whether and how seatbelt-use ...
Identifying Waveband Roughness in Highway Pavements Using Power Spectral Density Analysis
The international roughness index and the ride number are the most common road profile indices used throughout the world today, which are both based on the response of a simulated passenger car travelling at 80 km per hour. ...
