Project Summary
The Yakama Nation Department of Natural Resources (DNR) Engineering collaborated with the Smart Transportation Application & Research Laboratory (STAR Lab) at the University of Washington to develop a comprehensive roadway safety data visualization and evaluation platform. With the U.S. Department of Transportation’s Safety Data Initiative (SDI) fund, this tool will support information for the Yakama Nation government for their decision-making. The safety datasets provided in this tool consist of collision records (collision, vehicle, occupant, pedestrian) and roadway characteristics (roadlog, curve and grade, ramp, traffic information, special-use lane, etc.). The multi-source database supported data collection, quality control, integration, database management, visualization, and analytical results. The safety tools can be utilized for analytical and visualization functions such as crash data visualization, hotspot identification, and network screening. Examples of available safety data include crash type, frequency, severity, and risk estimate, and safety data download.
