A Bay Area Experiment in Electric Bike Sharing

In this post for The New York Times Green blog, I reported on a federally financed electric bike share program quietly coming together in the San Francisco Bay Area.

Rather than zigging and zagging to avoid steep inclines, e-bike users will be able to pedal up and over with help from an electric motor. For those hauling cargo, electric bicycle trailers will be available for hourly rentals, too.

City CarShare, a local nonprofit car sharing provider, is heading up the project, while the Transportation Sustainability Research Center at the University of California, Berkeley is responsible for assessing the impact and lessons learned.

City CarShare chief executive Rick Hutchinson told me about the nuts and bolts of the project, and the grand vision, too. “People will go to our site, pull down a list, and see maybe four cars and some electric bikes available for their errand or shopping trip or doctor’s appointment” The bikes will be cheaper than the cars. Seeing these options side by side, Mr. Hutchinson said, people who may not have considered biking before may ask themselves, “Could I do this on a bike?”

Green Moves: Medellin Cable Cars, San Francisco Parking Reform

Two cities renowned for the cable cars that traverse their hilly terrains—San Francisco, California, and Medellin, Colombia—captured this year’s Sustainable Transport Award from the Institute for Transportation and Development Policy (ITDP).

Reporting on the award for National Geographic Digital Media, I learned that Medellin’s system is one of very few aerial cable car systems used for mass transit, and the first of its kind in Latin America. Operating since 2006, it provides a crucial link to city life and work for residents of poor barrios high above the city center in the Aburra Valley.

San Francisco, meanwhile, made its mark in 2011 in parking reform, according to ITDP. The city not only introduced pricing schemes that vary based on time of day and real-time availability, but also traded some parking spots for public space, or “parklets,” as part of its “Pavement to Parks” program.

Review Roundup: Car-Sharing Services

It’s never been easier to be carless in the city. Not because of a boom in public transit, but because of car-sharing services, which make owning a vehicle akin to paying for a nanny instead of hiring the occasional babysitter.

So begins my review of four car-sharing services for Wired Magazine (October 2011). I tested Zipcar and the non-profit City CarShare, plus two P2P services, RelayRides and Getaround, on the streets of San Francisco. I checked out their insurance policies, mobile apps, application processes, websites, prices, availability, and more. For the full rundown and scores, head on over to Wired.

RelayRides Gets a Lift from G.M.’s OnStar

General Motors and RelayRides, a peer-to-peer car-sharing service that allows private car owners to rent their vehicles, announced a partnership and possible investment this week. Under an exclusive two-year agreement, RelayRides users will be able to unlock G.M. vehicles that are registered with the car-sharing service and subscribed to OnStar, the automaker’s communication service, with a mobile phone app. In this post for The New York Times Wheels blog, I explain the deal and why some people see the growing amount of computing power in cars as a “natural fit” for car sharing.

Smarter Trucking Saves Fuel Over the Long Haul

In my latest story for National Geographic Digital Media, I report how trucking companies are looking to boost fuel economy by improving driver behavior, and using on-board technology to monitor and control what goes on behind the wheel.

Just over 33 years ago, 33 truckers competed for three days in a fuel economy contest dubbed the “Double Nickel Challenge.” Named after radio slang for the 55 miles per hour speed limit then in force in the United States, the goal was simple: to test the claim, common among truckers at the time, that big rigs got better mileage at higher speeds.

Long-haul truckers from all over the United States gathered in East Liberty, Ohio, to watch as drivers navigated laps around a track-first at 55 mph, and then at any speed of their choosing. With a few exceptions, they burned less fuel in the first, speed-limited, trial.

More than three decades later, the double-nickel U.S. speed limit-enacted in the wake of the 1973 Arab oil embargo-has faded into history on most highways. But so has credibility for the claim that higher truck speeds beget better fuel economy.

Trading Oil for Natural Gas in the Truck Lane

Why would a company buy thousands of trucks and vans fresh off the assembly line and install a bulky and expensive new fuel system? As I report in my latest piece for National Geographic, it comes down to the bottom line.

In a time when natural gas is relatively cheap, but manufacturers build mostly gasoline and diesel models, companies like AT&T and Verizon have calculated it’s worth the expense to convert some gasoline vehicles to burn compressed natural gas. Read the full article here.

To Curb Driving, Cities Cut Down on Car Parking

Bit by bit, for the past 40 years, the city of Copenhagen has done something revolutionary: The Danish capital has reduced its parking supply. Cutting the total number of parking spaces by a small percentage each year stands in stark contrast to the more common pattern of cities adding more and more parking to accommodate private cars.

Bike-Share Schemes Shift Into High Gear

Around the world, cycle-hire operators are rolling out bicycles that were tucked away for the cold and rainy months. Hundreds of new bikes and docking stations will join existing fleets, while many more cities, from Kailua to Tel Aviv to the Big Apple are joining the bike-sharing wave for the first time.

Driving the Limit: Wealthy Nations Maxed Out on Travel?

Fewer cars are projected be on the road this summer in the United States, partly because of higher gas prices — but the leveling off of road travel in several countries goes beyond yearly fluctuations. Researchers now think the world’s most developed nations might have put the brakes on travel. Or, at least, on personal travel fueled by petroleum.

In the United States, Germany, Japan, and other countries that rank among the world’s wealthiest, there are signs that driving has reached a kind of saturation point, as I’ve reported in this article for National Geographic News.

Car Sharing Startups Bask in Zipcar’s I.P.O. Glow

Zipcar, the car-sharing provider, raised $174.3 million in an initial public offering Thursday morning, marking a first for a segment once dominated by nonprofits and local community organizations. In this piece for The New York Times Wheels blog, I report how the strong showing could be a boon for new companies aiming to make money through alternatives to vehicle ownership. Continue reading
