Crash severity modeling in transportation systems
… suitable countermeasures. In order to provide insights on the mechanism and behavior of the crash severity injury, a variety of statistical approaches have been utilized to model the relationship between crash severity and potential risk factors. Many of the traditional approaches for analyzing …

Adequacy of minimum passing sight distances for completing or aborting the passing maneuver
… on the adequacy of an acceptable gap and sight distance. This report presents an investigation of the adequacy of the current "Manual on Uniform Traffic Control Devices" (MUTCD) for marking on two-lane, two-way roads. It examines the existing criteria, problems associated with it and its …

Assessment of the Effects of Road Geometry on Irish Accident Rates and Driving Behaviour
… the road based on visible geometry or available sight distance. For example, drivers fixate on areas at the road bend while negotiating sharp bends and fixate further on or above the road surface when traversing straight segments.

Safety Issues Of Red-light Running And Unprotected Left-turn At Signalized Intersections
… Thirdly, geometric models to compute sight distances of unprotected left-turns were developed for different signalized intersection configurations including a straight approach leading to a straight one, a straight approach leading to a curved one, and a curved approach leading to a …

Accounting for Risk and Level of Service in the Design of Passing Sight Distances
… of various highway geometric elements. Passing sight distance (PSD) is an example of a geometric element designed with no risk measures. PSD is provided to ensure the safety of passing maneuvers on two-lane roads. Many variables decide the minimum length required for a safe passing maneuver. …
