The Los Angeles Department of Transportation needed a way to improve traffic, so it open sourced it.
“Cities increasingly see the value in open source as a way to save money, avoid vendor lock-in, and get access to the most capable, tested, and widely-supported technology solutions. Most cities aren’t looking to eliminate vendor relationships, but rather to make sure they’re getting the best value for the taxpayer money they spend on technology.”
This is true Smart City thinking.
