Written by is an crowdsourced map database of intersections that are potentially hazardous and annoying.  Our mission is to identify hazardous intersections for pedestrians, cyclists and drivers to raise the level of awareness of problematic intersections to driver and city officials to to improve safety. We seek to use media sources, DOT's, law firms, city, state, country and federal agencies to identify intersections with the following characteristics: high rates of accidents & fatalities (vehicles, bikes, pedestrians, motorcycles, trains) & dangerous railroad crossings.    
We started the to solve the problem of city, state, county & federal agencies lack transparency and consistency with information flow of accidents and fatalities. Since we launched the crowdsourced database in 2015, we have identified over 10,000+ intersections that are potentially hazardous to drivers and pedestrians. We also track what cities, states, counties and federal agencies are doing to improve these dangerous intersections by label these intersections in the database as "improved".  See list of reason why intersections are dangerous by design.

Hey Jeff Cohn , I'm Jasmine one of this year's online facilitators for the challenge. Thanks so much for sharing your idea! It sounds really beneficial for larger cities like Indianapolis. Does your website offer real time updates or does it only measure an intersection's potential to be hazardous?

Also there's another proposal that this idea would sync really well with. You should check out Smart City Technology for Individuals with Disabilities
