Safety At Intersections In Oregon: A Preliminary Update Of Statewide Intersection Crash Rates, Daniel R. Hazel
Safety At Intersections In Oregon: A Preliminary Update Of Statewide Intersection Crash Rates, Daniel R. Hazel
Civil and Environmental Engineering Master's Project Reports
This research aims to provide a preliminary update to statewide intersection crash rates for the state of Oregon using 2008-2013 crash data and a statewide sample of 129 intersections where two (or more) state-owned facilities intersect. Using intersections where state-owned facilities represent both the major and minor legs of the intersection allows for the maintenance of up-to-date intersection crash rates by eliminating time-intensive traffic volume data collection. Due to the frequency and severity of crashes at intersections, development of easily obtained intersection crash rates is important to assess trends and effectiveness of safety countermeasures employed at these locations in the …

Geospatial Analysis Of Rural Motor Vehicle Traffic Crashes In Oregon, Saad Nayef Almutairi
Civil and Environmental Engineering Master's Project Reports
This research examines the spatial extent of crashes in and around city boundaries in the state of Oregon in the U.S.A. For this study, a summary of fatalities data for the year 2006 obtained from NHTSA's report (2009), crash data for the year 2012, and city boundaries were obtained from ODOT "Oregon Department of Transportation" FTP: www.odot.state.or.us. In order to differentiate between the urban and rural crashes, city boundaries were used to find the numbers of urban and rural crashes. Outside areas of this urban-rural boundary were divided into further boundaries of 2.5 miles. An intersection tool in ArcMap …
