TL;DR: The results show that crash causation has shifted dramatically in recent years, with driver-related factors present in almost 90% of crashes, and definitively show that distraction is detrimental to driver safety, with handheld electronic devices having high use rates and risk.

TL;DR: The risk of a crash or near-crash among novice drivers increased with the performance of many secondary tasks, including texting and dialing cell phones, and among experienced drivers, the prevalence of high-risk attention to secondary tasks increased over time.

TL;DR: In this paper, the authors present a new, comprehensive, system-wide approach to identify critical links and evaluate network performance, which considers network flows, link capacity and network topology.

TL;DR: In this article, the authors evaluated the use of near crashes as a surrogate measure for assessment of the safety impact of driver behaviors and other risk factors, and concluded that using near crash as a crash surrogate provides definite benefit when naturalistic studies are not large enough to generate sufficient numbers of crashes for statistical analysis.

TL;DR: In this paper, several Bayesian models were developed to model the crash data from 170 signalized intersections in the state of Florida and the safety impacts of risk factors such as geometric design features, traffic control, and traffic flow characteristics were evaluated.
