This study evaluated the approach-level safety performance of left-turn phases at signalized intersections, including permissive, protected-permissive (PPLT), protected indications, and flashing yellow arrow (FYA). Data collection included exact dates of traffic signal changes, high-resolution datasets...

 

Over the last two decades, the use of advanced scientific and data-driven statistical methods has been continuously evolving to reduce the frequency and severity of crashes on our roadways. The American Association of State Highway and Transportation Officials (AASHTO) Highway Safety Manual (HSM) was...

 

Perception-reaction times (PRT) and deceleration rates are critical components in the design of highways and streets. This research has several objectives, including 1) evaluate differences in PRT and deceleration rates between crash and near-crash events, 2) assess the correlation between PRT and deceleration...

 

In an attempt to predict these crashes, North Dakota driver licensing data and crash data were used to develop a sample of 20,392 teen drivers age 14 to 17. Within the first year after being licensed, these drivers sustained 317 crashes that resulted in an injury or death. The resulting logistic regression...

 

North Dakota consistently experiences a relatively high level of crashes and injuries on rural roads, considering lane miles and vehicle miles traveled. Approximately 55% of the state's travel, in vehicle-miles, takes place on rural roads. North Dakota fatal crash reports from 2003 to 2007 show that...

 

Traffic safety is a widespread social concern. Tackling the problem requires understanding the people who are driving. This includes information about driver behavior, but also about perceptions these drivers hold regarding their driving. North Dakota crash data points at a specific group of drivers...

 
Accident Data Availability (Jun 2000, MPC-01-118)

This project investigates alternate forms of dissemination for the accident information. Costs, capabilities, and compatibility are reviewed for integration of the accident database with a GIS format to allow a graphical and spatial interface. The issues being addressed by this research focus on information...

 

This report documents steps counties and townships in North Dakota can take to minimize their tort liability with respect to closing roads, abandoning roads, or designating minimum maintenance roads. This information is intended merely to be a guide, and is not a legal opinion.

 

The primary objective of this research was to establish statistically valid mathematical models that can explain the variations in accidents as a function of geometric variables. Engineers and planners will be able to use these models to examine the sensitivity of accident rates to any of the independent...
