Gridlock Hackathon - Crowdsourced Innovation

What was the Gridlock Hackathon?

The Gridlock Hackathon was a one-of-a-kind hackathon to crowd-source innovative, implementable solutions from the tech community and concerned citizens to help ease Bengaluru’s traffic problem. Bengaluru, dubbed India’s Silicon Valley or India’s Startup Capital, is world-renowned for being a hub of innovation, cutting-edge research, and top tech talent. But the city also carries the tag of being India’s third-most populous urban agglomeration, having enjoyed for decades a preferred status among students, job-seekers and global companies. The population influx, combined with rising aspirations and inadequate infrastructure, has caused Bengaluru to burst at the seams, giving rise to a perennial problem: Traffic Gridlock.

Flipkart, as an innovative technology company born in Bengaluru, firmly believes that all new innovation should benefit society at large. Flipkart decided to bring together the developer community in the city and concerned citizen to collectively find workable solutions to Bengaluru’s traffic woes.

During the ‘Month of Innovation’ in June, part of Flipkart’s 10th anniversary celebrations, Flipkart invited these aspiring problem solvers to a ‘Gridlock Hackathon’ — a hackathon that crowd-sourced innovative, implementable ideas to help ease the city’s traffic situation.

The contest ran from June 7 to July 8. The Gridlock Hackathon invited technology-centric solutions, as well as those that partially leveraged technology through out-of-the-box thinking.

Gridlock Hackathon – Participation process

Interested participants submitted proposals that address macro problems like overall traffic in Bengaluru or traffic snares in specific areas (example: Silk Board Junction, KR Puram Junction, etc.). Submissions included a mix of entirely technology-centric solutions as well as ones that partially leveraged technology in relevant and smart way, to address problems related to Bangalore traffic.
