Google launched a public beta version of Google Transit for the Los Angeles metro area this weekend, after a long, hard wait. The partnership will be officially announced soon, following an initial testing period. In March, an anonymous source told LAist that Metro had a beta version ready to go and only needed to sign off on a public launch, which it was hesitant to do. In June, Metro released transit data sets for developers, setting off speculation that Google Transit for LA Metro would go live within the month. Et voila! There are still some kinks to be worked out, as reported by Militant Angeleno, who broke the story this morning, but here we are, catching up with Flagstaff and Fresno.
