Back in 2007 we covered Hitchsters, the New York site that combines social networking with ride-matching to help airport travellers share taxi rides and split the expense. Now, along very similar lines comes Taxi2, a beta project from Virgin Atlantic that's currently being tested in New York and London.

Touting the financial and environmental motivations for sharing a cab, Taxi2 is a free service for passengers of any airline. Users simply log on to the Taxi2 site and input their flight and destination details. From there, the system matches them with suitable cab-sharing companions and provides a protected way to contact them, allowing the travellers to decide whether to agree to the match. The system offers a way for female travellers to be matched only with other female travellers; it also protects all personal details. Once travellers agree on a match, Taxi2 even provides a printable and foldable sign to help them find each other at the airport. A mobile version of the technology is coming soon.

Much the way carpooling makes sense as a way to reduce the cost and impact of commuting to work, so cab-sharing seems like a no-brainer for all the many travellers heading in the same direction. One to emulate at a heavily frequented airport near you...?

P.S. Hitchsters is either temporarily offline, or permanently out of business. We'd love to know what happened to the company. If you have any information, please leave a comment. Thanks!

Aha Mobile is an iPhone app that offers drivers location-based information and entertainment. A personally tailored audio stream not only provides up-to-the-minute traffic info, but also features "shouts"—15 second snippets recorded through the application by other drivers in the area. The idea is that drivers can help each other out by sharing reports on road conditions, extending the real-time connectivity that people have on Facebook or Twitter. Furthering the social element, drivers can belt out tunes in the Caraoke Room, or vent their road rage in the Bad Driver Shout Room.

Aha Mobile's on-screen information is designed to be easily navigable and digestible at a glance; although for safety reasons, people should of course keep their hands off their iPhones while driving. Roadside services can be located with the help of Yelp and SitOrSquat by answering simple on-screen questions: "Hungry?" "Need coffee?" "Need a bathroom?" Drivers can also get alerts when they're approaching red lights or speed cameras.

Aha Mobile's service is available across the US, with special emphasis on the most heavily trafficked urban areas. One to bring to highways and byways in other parts of the world?

The world of iPhone apps is increasingly crowded. And while there are several that help users to find convenient meeting points, MeetMe is the first one to integrate both Google Maps and Yelp reviews.

In order to find an appropriate meeting location, users input Point A and Point B, and the type of venue they'd like to meet at. For instance, users can pinpoint the best sushi restaurant halfway between Boston and Philadelphia, or a romantic hotel between York and Manchester. The USD 1.99 app then provides a list of suitable locations complete with Yelp recommendations. Once a location is selected, MeetMe emails both parties a map complete with driving directions. If users prefer to meet closer to one point or the other, the distances can be adjusted. MeetMe points out that the app can also help plan road trip stopping points. MeetMe works worldwide and, according to reviews, has fewer accuracy problems than most mapping apps. It's also ad-free, so users can be sure the recommendations they're receiving aren't promos in disguise.

In theory, the app could help cut down on miles traveled because both parties will be encouraged to drive the shortest possible distance, instead of relying on meeting points that are familiar to both, but might not be most efficient. Mobile applications like MeetMe aren't just convenient tools for consumers—if widely adopted, smart navigation can reduce miles travelled and hours spent on the road. It can also help prevent congestion by feeding commuters real-time and predictive road data about potential traffic jams. As our everyday tools become ever more sophisticated at navigating cities, opportunities abound for entrepreneurs than can help us unlock location-based data in useful and intuitive ways.

As the number of people who are twittering continues to rise, more and more businesses are adding to their existing methods of communicating with (potential) customers. An innovative example was recently introduced by London's eco-taxi service greentomatocars. The company, which we covered when they launched back in 2006, claims to be the first private hire service in the UK to take bookings via Twitter. Users simply send a direct message to @greentomatocars with the booking details, receive a tweet back with a unique booking reference, and wait for a Prius to pull up. Besides using Twitter for bookings, greentomatocars also hopes to encourage debate about environmental issues.

Although Twitter hasn't released hard data on how many active users it has, the service seems to be having a profound effect on business-to-customer communication, enabling companies to engage in an immediate, ongoing and intimate conversation with customers and potential customers, creating a better mutual understanding and forging brand loyalty.

There's been plenty of lip service paid to electric vehicles in recent years, but the fact remains that in many communities, they're still more frequently discussed than actually seen. Not so in several U.S. neighbourhoods, however, where golf carts and other diminutive electric vehicles are part of the very fabric of community life.

With many of the same gas-free benefits offered by larger electric vehicles—but considerably lower price tags—neighbourhood electric vehicles, or NEVs, are the transportation of choice for residents of several large retirement communities, an article on Wired.com recently reported. Golf carts are a common sight on the streets and specially designed paths of The Villages community in Florida, for example—and not just the ordinary, plain-vanilla variety. In fact, many of the community's 77,000 retired residents "pimp their rides" to look like fire trucks, 1930s roadsters and stretch limos, Wired reported, spending as much as USD 20,000 in the process of swapping in bigger tires or hacking engines to surpass the traditional golf cart's maximum speed of about 20 mph. Similar sights are apparently seen in other communities around the country, including the retirement mecca of Sun City, Arizona, and the all-ages suburb of Peachtree City, Georgia. Accessories are sold by companies like GoNEV.

Driver's licenses are not typically required for most golf carts, but full-fledged NEVs—which are street-legal in most states—require insurance and registration, Wired reported. Either way, such vehicles offer not only eco-benefits and credentials, but apparently also those of the more neighbourly kind: "If your neighbour is in his yard, you can't drive by in your golf cart without waving and saying hello," Gary Lester, VP of community relations for The Villages, told Wired. Chrysler's Global Electric Motorcars is one major maker of NEVs, selling its vehicles for as low as USD 3,644 with tax credits.

Lower prices, fewer emissions and social benefits on top of an eco-iconic appearance and government tax incentives? Legal and insurance issues notwithstanding, sounds like a potential winner to us. Who will put golf carts at the forefront of *your* community's next planning venture...?
