    It's become a given that ride services like Uber et al are disrupting city mobility, but for all the digital ink spilled over that trend, we don't have much data on what exactly the disruption looks like. (That is, other than the occasionally questionable data the services supply themselves.) So it's important for outside observers to pull the veil back a bit, and a research team at UC-Berkeley led by Lisa Rayle has done just that with a new working paper on "ridesourcing" services, as they're calling Uber, Lyft, Sidecar, and friends.

  • Michael Cassidy, a professor at UC Berkeley's Civil and Environmental Engineering department, has studied the phenomenon on Bay Area highways by carefully measuring freeway traffic with sensors and cameras..."Of all the maneuvers, it's probably the most disruptive to traffic," he said of the shenanigan.

  • If "Goldilocks and the Three Bears" were written today, bike-share stations would play the role of the porridge. A station that's too full is a bad thing, because that means riders can't return a bike there. A station that's too empty is also a bad thing, because that means potential riders can't rent from there. To keep members happy, you need to get the number of bikes at a station just right.
