Matching GPS Records to Digital Map Data: Algorithm Overview and Application
(National Surface Transportation Safety Center for Excellence, 2015-03-03)
Records of latitude and longitude pairs describing an approximate path of travel are logged by many types of Global Positioning System (GPS)-enabled devices. These logs of latitude/longitude (lat/lon) pairs specify geographic ...
Using Functional Classification to Enhance Naturalistic Driving Data Crash/Near Crash Algorithms
A persistent challenge in using naturalistic driving data is identifying events of interest from a large data set in a cost-effective manner. A common approach to this problem is to develop kinematic thresholds against ...
Time Series Analysis of Driver Behavior on Curves
Over half of motor vehicle fatalities are roadway departures, with rural horizontal curves being of particular interest because they make up only a small share of the system mileage but have a crash rate that is significantly ...
Evaluation of Older Driver Fitness-to-Drive Metrics and Driving Risk Using Naturalistic Driving Study Data
(National Surface Transportation Safety Center for Excellence, 2015-07-28)
In this study, we evaluated the relationship between older drivers’ fitness assessment profiles and their driving risk, represented primarily by crash and near-crash (CNC) rate, and secondarily by high g-force (HGF) event ...
Naturalistic Driving Study: Technical Coordination and Quality Control (SHRP 2 Report S2-S06-RW-1)
(Transportation Research Board, 2015)
Researcher Dictionary for Safety Critical Event Video Reduction Data
(Virginia Tech. Virginia Tech Transportation Institute, 2015-10-06)
This data dictionary describes the video reduction variables available in the Second Strategic Highway Research Program (SHRP 2) Naturalistic Driving Study data set for use by the research community. The data dictionary ...
Drivers' Visual Behavior When Using Hand-Held and Hands-Free Cell Phones
This study investigated driver distraction and how the use of handheld (HH), portable hands-free (PHF), and integrated hands-free (IHF) cell phones affected the visual behavior of motor vehicle drivers. Method A naturalistic ...
Variability in Crash/Near-Crash Risk Among Novice Drivers
Using video monitoring technologies, we investigated teenage driving risk variation during the first 18 months of independent driving. Driving data were collected on 42 teenagers whose vehicles were instrumented with ...
Constructing a Distracted Driving Dataset
Distracted driving has become a topic of critical importance to driving safety research over the past several decades. Naturalistic driving data offer a unique opportunity to study how drivers engage with secondary tasks ...
Common Data Elements between the Large Truck Crash Causation Study Investigations and Commercially Available Onboard Monitoring Systems
At the heart of traffic safety is the identification of factors that lead to crashes. With this knowledge, interventions can be developed to mitigate or prevent these factors from occurring in the future. Post hoc ...
