Perception-reaction time (PRT) and deceleration rate are two key components in geometric design of highways and streets. Combined with a design speed, they determine the minimum required stopping sight distance (SSD). Current American Association of Highway Transportation Officials (AASHTO) SSD guidance is based on 90th percentile PRT and 10th percentile deceleration rate values from experiments completed in the mid-1990s. These experiments lacked real-world distractions, and so forth. Thus… 
Investigation of driver behavior during crash and near-crash events using naturalistic driving data
Various studies demonstrated that the human factors, driver performance, and the interactions among humans and other elements in the transportation systems significantly contributed to the traffic
IIN OUR INCREASINGLY LITIGIOUS SOCIETY, it seems to be increasingly the case that, in the event of an incident, the argument is made in a court of law that noncompliance with laws, rules or
Investigating the impact of correlation on system multimode reliability-based analysis of highway geometric design
Results show that ignoring the correlations between input-variables can lead to inaccurate estimation of the noncompliance probability for both the individual modes and the series-system reliability.
New models for dynamic choice contexts: further steps towards bridging choice modelling with mathematical psychology
It is demonstrated that analytical and simulated versions of DFT as well as quantum models provide a better account of behaviour than models based on more traditional methods.

It is proved that head pose can be used to detect drivers’ distraction using a convolutional neural network, and can beused for the development of advanced driver assistance systems.
Ocular Influence of Nano-Modified Fullerene Light, 2: Time Correlation of the Choice and Simple Sensorimotor Reactions That Determine Blinding Compensation of the Driver
A decrease in correlation of the latent periods of a simple sensorimotor reaction and the CR when using light modified by fullerene is revealed, which indicates an improvement in the rate of inter-hemispheric information processes and improved in the quality and effectiveness of decisions made.

Evaluation of Driver Behavior at Signalized Intersections
Time-lapse photography was used to study driver behavior associated with the traffic signal change interval at a total of six intersections in the Phoenix and Tucson metropolitan areas. In addition,
Driver Braking Performance to Surprise and Expected Events
Meta-analyses have shown that the driver braking characteristics reported in the literature often vary due to differences in study methodologies (Green, 2000; Muttart, 2005; Summala, 2000). This
"How Long Does It Take to Stop?" Methodological Analysis of Driver Perception-Brake Times
The most important variable is driver expectation, which affects RTs by a factor of 2.5, and these times are modulated somewhat by other factors, including driver age and gender, cognitive load, and urgency.
Quantile regression provides a fuller analysis of speed data.

Safety Impacts of Design Exceptions on Nonfreeway Segments
Safety (in terms of expected crash frequency and severity) was compared on road segments where design exceptions had been approved and constructed and on similar road segments where no design
