In order to fully understand the research progress of human factors and traffic safety in curve
driving, from the perspective of driver-vehicle-road-environment dynamic traffic system, this …

Speed and speed variation are closely associated with traffic safety. There is, however, a
dearth of research on this subject for the case of urban arterials in general, and in the …

Vehicle operating speed is a crucial factor for road safety, as it strictly affects occurrence and
severity of crashes. Usually, 85th percentile of the operating speed distributions (ie, V 85) in …

Analyzing speed mean and variance is vital to safety management in urban roadway
networks. However, modeling speed mean and variance on structured roads could be …

Inappropriate speeds are key factors that may affect the occurrence and the severity of road
crashes. Although rural roads are influenced by more severe crashes than urban roads …

Researchers have studied two-lane rural highways to predict the operating speed on
horizontal curves and correlated it with safety. However, the driving characteristics of four …

In this study, the 85th and 98th percentile speed prediction models of car, light, and heavy
commercial vehicles for four-lane divided horizontal curves in rural highways were …

Poor coordination between geometric elements of horizontal curves can lead to unsafe
speed. This study evaluated the effect of horizontal curve geometry on vehicle speed …

Vehicle operating speed measured on roadways is a critical component for a host of
analysis in the transportation field including transportation safety, traffic flow modeling …

The available sight distance (ASD) is the maximum length of the roadway ahead visible to
the driver. It is a fundamental factor in road geometry principles and is used by road …
