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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
