TechCrunch says: Strategic Sharing: Zipcar Leads $13.7M Investment In Campus Car-Sharing Startup Wheelz:

“Well, you have to hand it to the strategy team over at Zipcar. Arguably the largest on-demand car-sharing network, Zipcar went public last year and not long after saw its market cap cross $1 billion. It’s since fallen back, and with collaborative consumption and the market for car-sharing heating up, the big players have to make moves. Zipcar has since forged a partnership with Ford, making it the largest provider of cars for Zipcar’s University program, and, in December, the company took a controlling stake in Spain’s largest car-sharing network, Avancar.
Today finds Zipcar making another strategic move to get its mitts in fellow car-sharing companies, again with a focus on universities, whose students are among the most eager adopters of car-sharing models. What do I mean? The company today announced that it is a lead investor in the $13.7 million Series A financing of Wheelz, a junior, university-focused version of itself.”

“To enable all that, Google introduced a new standard in 2011 called GTFS-realtime. It builds on GTFS, but is a different animal, since it includes new feed types for trip updates, service alerts, and vehicle positions, as well as provisions for constantly refreshing this data throughout the day. In an advisory to agencies, Google puts it this way: “Because GTFS-realtime allows you to present the actual status of your fleet, the feed needs to be updated regularly—preferably whenever new data comes in from your Automatic Vehicle Location system.””
