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 ...
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 ...
Roadway Epochs: Documentation and User Manual
(National Surface Transportation Safety Center for Excellence, 2015-08-24)
This report describes the contents of the Roadway Epochs Database, which is a collection of tables providing indices for users to access vehicle data from the 100-Car and Second Strategic Highway Research Program (SHRP 2) ...
Identification of Cognitive Load in Naturalistic Driving
(National Surface Transportation Safety Center for Excellence, 2015-07-28)
Over the last decade, naturalistic driving studies have provided significant insight into issues pertaining to the roles of distraction, inattention, and drowsiness in crash risk. New techniques have been developed for ...
Evaluating the Influence of Crashes on Driving Behavior using Naturalistic Driving Study Data
(National Surface Transportation Safety Center for Excellence, 2015-07-16)
It is hypothesized that intense events such as crashes could influence driver behavior and driving risk. This study evaluated the influences of crash events on driver behavior and driving risk using data from the 100-Car ...
