Optimal sensor placement for measuring operating speeds through curves on rural two-lane highways

Creator:: Mecham, Megan E.
Abstract:: Operating speed is one of the best performance measures that can tell transportation agencies how well or how poorly the transportation system is functioning. Fluctuating operating speeds often mean there is a design flaw or something about the physical road design that violates drivers' expectations. A primary example of this...

Safety performance of curve advisory speed signs

Creator:: Avelar Moran, Raúl Eduardo
Abstract:: Posting advisory speed signs at sharp horizontal curve sites is a practice well established in the United States. The purpose of these signs is to provide the driving public with a safe speed to negotiate such curves; however, the link between these signs and safety has not yet been clearly...

A Review of Current State Department of Transportation Practice for Promoting and Documenting the Safety of Field Employees

Creator:: Barlow, Zachary Wesley
Abstract:: State Departments of Transportation (DOTs) are the primary owners of roadway infrastructure in the United States. Many of the employees of state DOTs work on roadway work sites, putting them at disproportionately higher risks of injury or fatality. A review of the literature determined that a combination of policies, standards,...

Driving simulation : a mechanism for understanding driver response to mobile barriers in work zones

Creator:: Swake, Joshua
Abstract:: Highway construction projects require temporary changes in roadway characteristics, such as the number of operational lanes, lane path, lane width, shoulder width, and posted speed limit. These modifications which are often temporary in nature have the potential to impact driving performance. Many research efforts have focused on developing standards to...

Data assessment in Oregon for SafetyAnalyst based on Highway Safety Manual Part B

Creator:: Li, Meng
Abstract:: The author of the Highway Safety Manual (HSM) Part B developed a predictive method for safety management. A software tool for highway safety system analysis called the SafetyAnalyst is developed basing on HSM Part B. The author describes an effort to evaluate the feasibility of SafetyAnalyst in Oregon. Seven sample...

Pedestrian safety at signalized intersections operating the flashing yellow arrow

Creator:: Tuss, Halston
Abstract:: At signalized intersections, pedestrians are considered to be amongst the most vulnerable. When in the crosswalk at intersections without protected left-turn phasing, pedestrians are particularly at risk from left-turning vehicles. Until recently, a wide variety of indications were in use across the US to indicate a permissive left-turn condition to...

The Evaluation of Engineering Treatments for Right-Hook Crashes at Signalized Intersections with Bicycle Traffic

Creator:: Warner, Jennifer Lynn
Abstract:: A right-hook crash is a bicycle-motor vehicle crash between a right-turning motor vehicle and an adjacent through-moving bicycle. This study focuses on right-hook crashes that occur during the latter stage of the circular green indication at signalized intersections with shared right-turn and through lanes. The overall objective was to evaluate...

Safety and efficiency benefits of traffic signal countdown timers : a driving simulator study

Creator:: Islam, Mohammad Rabiul
Abstract:: Traffic signal countdown timers (TSCT) are innovative, practical and cost effective technologies with the potential to improve efficiency and safety at signalized intersections. The purpose of these devices is to assist motorists in decision making at signalized intersections with real time signal change information. While successful implementation of these devices...

Using the predictive method in the 2010 Highway Safety Manual to identify hazardous intersections in Corvallis, OR

Creator:: Zhou, Yanfen
Abstract:: An intersection, due to its vehicle and pedestrian conflict movements, experiences complex traffic situations that might contribute to crashes. In the city of Corvallis, OR, historically more than 80% of the total crashes have occurred within an intersection or have been designated as intersection-related. It is important to develop a...
