Spatial Analysis of Bicycle Count Data
(2017)Every year since 2010, volunteers from more than 50 communities have helped the Washington State Department of Transportation (WSDOT) collect bicycle count data. This project created the AADB Estimation website that ... -
SSI-Bridge 2: Soil-Bridge Interaction During Long-Duration Earthquake Motions
(2015)Subduction zone earthquakes are characterized by their large magnitudes, which produce many cycles of strong ground shaking, and thus, long-duration earthquake motions. The Pacific Northwest is prone to subduction zone ... -
SSI-Bridge: Soil-Bridge Interaction During Long-Duration Earthquake Motions
(2014)The seismic response of a complete soil-bridge system during shallow, crustal and subduction zone earthquakes is the topic of this report. Specifically, the effects of earthquake duration on the seismic performance of ... -
Streamlining the Crash Reporting Process in the Pacific Northwest
(2018)Over five million traffic crashes are reported annually in the United States, and the documentation process for every single crash begins at the scene of the incident with information gathered by a member of the law ... -
Taming and Tapping the Bikeshare Explosion: A Review of shared micro-mobility laws
(2020)This project analyzed the various laws pertaining to shared micro-mobility systems, such as bike-share and scooter-share. In order to examine the relevant laws in all 50 states, the research team developed a list of questions ... -
Testing of Cavity Attenuation Phase Shift Technology For Siting Near-road NO2 Monitors
(2015)Recent research has identified the public health importance of air pollution exposures near busy roadways. As a result, the Environmental Protection Agency (EPA) significantly revised its Nitric oxide (NO2) air quality ... -
Torsional Safety of Highway Traffic Signal and Signage Support
(2017)Deep foundations may need to resist torsional loads resulting from wind loading on traffic sign and signal pole structures, or seismic loading on curved or skewed bridges. Although methods for designing deep foundations ... -
Transportation Corridor Resiliency in the Face of a Changing Climate
(2018)The effects of a changing climate on transportation corridor slopes are poorly understood, but several recent studies have suggested that landslide activity, especially rockfall, is likely to increase as a consequence of ... -
Understanding Freight Behavior in the Pacific Northwest: An Evaluation and Application of EROAD Data to Freight Demand and Forecast Modeling
(2020)The overall objective of this work was to utilize a previously unused private data source to analyze freight movements in the Pacific Northwest. This objective was achieved through the use of private data acquired as part ... -
UNDERSTANDING FREIGHT BEHAVIOR IN THE PACIFIC NORTHWEST: AN EVALUATION AND APPLICATION OF EROAD DATA TO FREIGHT DEMAND AND FORECAST MODELING
(2020-01)The overall objective of this work was to utilize a previously unused private data source to analyze freight movements in the Pacific Northwest. This objective was achieved through the use of private data acquired as part ... -
Understanding Truck Parking Behavior and Choice of Commercial Motor Vehicle Operators: Impacts on Roadway Safety
(2018)It is nationally recognized that commercial motor vehicle (CMV) operators often cannot find adequate and safe parking for rest purposes. This is especially true for the Pacific Northwest, where high-use corridor rest areas ... -
Unmanned Aircraft System Assessment of Landslide Safety for Transportation Corridors
(2016)An assessment of unmanned aircraft systems (UAS) concluded that current, off-the-shelf UAS aircraft and cameras can be effective for creating the digital surface models used to evaluate rock-slope stability and landslide ... -
The Use of Synthetic Blended Fibers to Reduce Cracking Risk in High Performance Concrete
(2014)Transportation departments have observed varying degrees of cracking in their concrete structures. Cracking of high performance reinforced concrete structures, in particular bridge decks, is of paramount concern to Pacific ... -
Washington State School Walk Score
(2020)We used unique data from the 2016 Washington State Student Travel Survey combined with built environment data to first confirm the factors shown to influence children walking to and from school in previous literature. ...
