The Gouda, The Bad, And The Ugly: Prioritizing Intersections For Pedestrian Safety In Tillamook, Or With Different Risk Estimation Methods, Kelly M. White
The Gouda, The Bad, And The Ugly: Prioritizing Intersections For Pedestrian Safety In Tillamook, Or With Different Risk Estimation Methods, Kelly M. White
Civil and Environmental Engineering Master's Project Reports
The following report explores five different pedestrian risk estimation methods at urban intersections. Six study intersections in Tillamook, Oregon were chosen as a case study to analyze each risk estimation method and apply the values to a project prioritization process. Ultimately, risk factors of both exposure and infrastructure contribute to the highest amount of risk for pedestrians. The Oregon Department of Transportation's State Planning and Research Report 779 was identified as the most comprehensive risk estimation method.

Exploring High-Resolution Data Obtained From Asc/3 Controller Of Intersection Se Division St & Se 122nd Ave, Portland, Oregon, Naowar Al-Abbas
Civil and Environmental Engineering Master's Project Reports
High-resolution data obtained from ASC/3 controllers can be used to create a variety of performance measures, helping engineers and professionals in monitoring intersection performance, identifying issues, and making proper improvements. These measures concern the intersection quality of the progression, capacity, and non-vehicular operations (e.g. pedestrian crossings). In this report, we explored high-resolution data obtained from the intersection of SE Division Street and 122nd Avenue. This intersection had some safety concerns as it is considered one of most dangerous intersections in Portland, Oregon. Thus, the first variable we examined from the data was pedestrian wait time when a cross request is …

Over the last decade, the transportation agencies in Oregon have systematically enhanced many pedestrian crossings at mid-block locations with Rectangular Rapid Flashing Beacons (RRFBs), Flashing Yellow Beacons (Flash), and high visibility crosswalk markings (Hi-Vis). Enhancements often included the installation of refuge medians. This study explored the safety performance of these enhanced crossings, categorized by enhancement type. Data were collected on 191 crossings that included installation year, geometric features, surrounding land use, traffic volumes, and the number of crashes. Because pedestrian volume at the locations was unavailable, a pedestrian activity level variable was developed. Target crashes for analysis were identified as …

Over the last decade, the Oregon DOT and other agencies have systematically implemented many pedestrian crossing enhancements (PCEs) across the state. This study explored the safety performance of these enhanced crossing in Oregon. Detailed data were collected on 191 crossings. Supplemental data items included crossing location information, route characteristics, surrounding land use and crossing enhancement descriptions. Pedestrian volume at the crossing locations was a highly desirable but unavailable data element. To characterize pedestrian activity, a method was developed to estimate ranges for pedestrian crosswalk activity levels based on the land use classification at the census block level and the presence …
