Application of Proximity Sensors to In-vehicle Data Acquisition Systems
(National Surface Transportation Safety Center for Excellence, 2018-05-02)
Naturalistic driving studies rely on human data reductionists to manually review and annotate driving behaviors. This work is time-consuming, and algorithms that could scan and categorize video data could make the data ...
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, ...
Using Functional Classification to Enhance Naturalistic Driving Data Crash/Near Crash Algorithms
(2015-01-20)
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 ...
Common Data Elements between the Large Truck Crash Causation Study Investigations and Commercially Available Onboard Monitoring Systems
(2015-01-28)
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 ...
Variability in Crash/Near-Crash Risk Among Novice Drivers
(2014-08-25)
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 ...
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 ...
Integrating the Adaptive Lighting Database with SHRP 2 Naturalistic Driving Data
(National Surface Transportation Safety Center for Excellence, 2015-09-16)
This report details efforts to integrate the Adaptive Lighting Database (ALD) with the Second Strategic Highway Research Program (SHRP 2) Naturalistic Driving Study (NDS) and the Roadway Information Database. The ALD ...
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 ...
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 ...
Time Series Analysis of Driver Behavior on Curves
(2014-08-25)
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 ...
