Allston-Brighton residents file the most complaints about graffiti, adding a bike lane on Blue Hill Avenue would be the best way to cut down on accidents, and Hub residents find trash problems more irritating than slow snow removal.
Those are some of the revelations from Boston's latest HubHack hackathon, which asked techies to dig into a haystack of data and come up with needles.
"We want to deliver services in a whole different manner as we move forward," Mayor Martin J. Walsh said. "This is an exciting time in the city of Boston, we're doing an awful lot around social media and hackathons ... things that the city has never seen before."
About 70 people in 17 teams worked with everything from traffic and accident data from GPS app Waze to census data to Boston's crime information, in order to highlight trends and uncover insights that could be useful to the city. Seven finalists unveiled their analyses yesterday at Faneuil Hall. Some things they found include:
• Blue Hill Avenue has the highest collision rate for cyclists, so adding a bike lane there would give the city the most bang for its buck.
• Commonwealth Avenue, widely considered the most dangerous for cyclists, has a relatively low collision rate based on how many people ride down that street.
• The day of the week with the most crime is Friday, followed by Saturday and Thursday.
• Issues with trash pickup and sanitation make residents angrier than snow removal problems, according to a language analysis of Citizens Connect complaints.
• Beacon Hill ranks 14th in total Citizens Connect complaints, but ranks second for complaints about street lights. South Boston leads in complaints about trees, and Allston-Brighton leads in complaints about graffiti.
• A whopping 43.3 percent of the residents in the college-packed Fenway/Kenmore area are between 15- and 20-years-old.
• Most neighborhoods are relatively split in terms of gender, except East Boston, which is 57 percent male.
"It's an exciting opportunity for us, for operational purposes, to help us better understand the city," said Jascha Franklin-Hodge, the Hub's chief information officer, adding the data visualizations could be used to improve city services. "The work that's being done around public safety and bike lanes may inform some of our priorities and our decision-making."
That project, which compared accident rates on streets with and without bike lanes, won first prize.
The hackathon marked the second time the city has opened up some of its information to outsiders. Last year, a hackathon focused on improving the city permitting system and three of the apps built then have been implemented.
