Risk evaluation of multiple passing maneuvers on two-lane rural highways in Iran.

The passing maneuver (PM) on two-lane rural highways is a very complicated driving task because it is associated with the risk of a head-on collision. It can be more risky for multiple PMs where a single vehicle passes at least two other ones. Using the time-to-collision (TTC) indicator, this paper addressed the risk of multiple PMs and developed a logistic regression model to predict the occurrence probability of a serious head-on conflict defined with a TTC of <3 sec-threshold.

A model to identify high crash road segments with the dynamic segmentation method.

Currently, high social and economic costs in addition to physical and mental consequences put road safety among most important issues. This paper aims at presenting a novel approach, capable of identifying the location as well as the length of high crash road segments. It focuses on the location of accidents occurred along the road and their effective regions.
