The City for All hackathon was a big civic hit over the weekend. Nine teams competed for recognition and prizes at City Hall’s Bertha Knight Landes room. The theme of the hackathon was to find solutions for the challenges of aging and accessibility. The winner for Best Overall Innovation was the Pandora for Streets/Smellevation Maps team which addressed several of the eight domains of livability in a single app. The app would also include paths in Seattle that present the best smells, sounds, views, and hills. Users can rank how important each aspect is to improve the algorithms of the app. The winner of Best Accessibility Hack was GoInfo Game which gamified the collection of bus stop information that’s crucial for disabled riders. The Winner of Best Use of Open Data and and Best Data Visualization was SeaSidewalks which developed a visualization of data from SDOT’s recent Citywide sidewalk analysis. The team came up with a mechanism for prioritizing sidewalk issues based on factors like proximity to hospitals and other key facilities.
