Study finds NYC Clean Air Taxi rules successful in cutting pollution

New York City Clean Air Taxi rules are successful in cutting emissions and reducing air pollution, https://www.mailman.columbia.edu/public-health-now/news/clean-air-taxis-cut-pollution-new-york-city-study to a new study by researchers at the Columbia University Mailman School of Public Health and Drexel University. Between 2009 and 2015, the legislation more than doubled the fuel efficiency of the fleet of 13,500 yellow taxis, leading to estimated declines in air pollution emissions. The findings are published in the Journal of Exposure Science & Environmental Epidemiology.

The scientists report that overall fuel efficiency of the medallion taxi fleet climbed from 15.7 to 33.1 mpg, and corresponding estimates of nitric oxide (NO) and total particulate (PMT) exhaust emissions declined by 82% and 49%, respectively. They also found these emission reductions were associated with decreases in concentrations of pollutants in the city’s air.

Introduced in 2006, Clean Air Taxi legislation mandated that at least 9% of new medallions for yellow taxis be set aside for hybrid or compressed natural gas vehicles, and incentivized the purchase of low-emission taxis by extending the allowed period of models classified as “clean air” by the United States Environmental Protection Agency. Clean Air Taxi laws do not regulate the city’s 100,000 for-hire vehicles such as Ubers and Lyfts which are governed by separate laws and regulations.

The past decade has seen steady improvements in the quality of air in New York City, and clean-air taxis appear to be one contributing factor.

The researchers created maps to measure taxi traffic intensity across the city and used inspection and trip data to approximate taxi-related exhaust emissions of two major sources of air pollution: nitric oxide and particulate matter. They then used New York City Community Air Survey data collected at more than 100 monitoring sites across the city to estimate the impact of these changes.

The biggest effect was seen in Manhattan neighborhoods with a high density of yellow taxis—not in low-income and outer borough areas with elevated rates of respiratory illness. The authors say this finding suggests other policies are needed to make meaningful advances in improving respiratory health.

This study provides evidence that air pollution legislation can have real impact. Even though overall, yellow taxis account for a small proportion of vehicular miles traveled on New York City’s streets, in midtown they account for almost half. Similar regulations targeting other vehicles could make an even bigger difference.

Maven Says Uber and Lyft Drivers Love Chevy Bolt

General Motor’s Maven car sharing unit finds that Uber and Lyft drivers love the Chevy Bolt and are putting a lot of miles behind the wheel.

Rachel Bhattacharya, who heads GM’s commercial mobility unit, spoke about it yesterday at a CAR Management Briefing Seminar in Traverse City, Mich.

The Maven fleet brought in 150 Bolts during May, and has 250 more on order.

Bolt rentals have done very well through the Maven Gig program, where ride-hailing and delivery service drivers rent a Maven vehicle for a week at a time. Maven Gig launched in May in San Diego and has expanded to San Francisco.

Drivers pay more for the Chevy Bolt under the program than they would under other Maven rentals; but they end up saving money on fuel costs.

Drivers pay $229 for the weekly rental, which covers insurance, maintenance, and charging. It’s about $40 more than other rentals, but drivers end up saving about $70 a week on fuelcosts, the GM executive said.

“Early interest has been phenomenal,” Bhattacharya said. “For most of them, it’s not about environmentalism. It’s about fuel savings.”

It’s taken off in the past three months. The GM mobility executive said that drivers are putting an average of 30 percent more miles in the Bolt than while driving cars with internal combustion engines.

Maven customers have put in more than 1 million miles during their Bolt rentals since the offer was launched in May.

The car sharing service is doing business now in 17 North America since its startup 18 months ago. Besides Maven Gig, the Maven Home service has done well with customers living in apartment and condo complexes and needing short trips in a shared rental car.

Bhattacharya said established brands like Zipcar helped open the door for Maven.

GM has the advantage of getting young consumers to try out car sharing services and its own vehicle products, which could the first car they end up buying.

It’a also setting the stage for testing self-driving Bolts through its partnership with Lyft and through its Maven subsidiary,

“The whole goal of Maven is we’re the learning laboratory for General Motors as we’re preparing for an autonomous future,” she said. “We’re still very much in startup mode, but we’ve had some positive results to date.”

GM Readying Thousands Of Self-Driving Bolts For 2018

General Motors plans to be the first company to bring thousands of self-driving vehicles to roads through its partnership with ride-hailing firm Lyft.

Two sources familiar with GM’s plan told Reuters last week that thousands of self-driving all-electric Chevrolet Bolts will roll out by 2018, with most of them going to Lyft.

The automakers has no immediate plans to sell autonomous Bolts to the public, the sources said.

Lyft declined to comment, but GM hasn’t denied the report.

“We do not provide specific details on potential future products or technology rollout plans. We have said that our AV (autonomous vehicle) technology will appear in an on-demand ride sharing network application sooner than you might think,” GM said in a Friday statement.

So far, Alphabet’s Waymo self-driving car subsidiary has the most autonomous vehicles on the roads with about 60 being tested in four states. Ford has a similar plan to GM’s with self-driving ride sharing fleets scheduled to come out in 2021. Fiat Chrysler Automobiles will be providing a few Chrysler Pacificas to Waymo for conversion to self-driving test minivans.

Reuters, which broke the story Friday, thinks that its November interview with GM executive Mike Abelson shed some light on the subject. Though he isn’t the first company executive to discuss GM’s AV strategy, with several of them acknowledging during interviews that self-driving cars will be mass produced and deployed in mobility fleets. Details on scale of production and timing of deployment were left out.

Ableson told Reuters that GM carsharing service Maven will likely be included in the roll out of self-driving Bolts for fleet testing. Maven and Lyft are likely to find more business opportunities with the first wave of more costly autonomous vehicles.

“If you assume the cost of these autonomous vehicles, the very early ones, will be six figures, there aren’t very many retail customers that are willing to go out and spend that kind of money,” Ableson said. “But even at that sort of cost, with a ride sharing platform, you can build a business.”

In December, the company revealed that fully automated Bolts will starting being built in early 2017 at GM’s Orion Township plant in the Detroit area. Testing of about 40 self-driving Bolts will also come to Detroit this year after the first wave was tried out in San Francisco and Scottsdale, Ariz.

Abelson suggested in his November interview that GM could be uniquely positioned to engineer, manufacture, and test out AVs at a high-volume scale.

“If you take those three things, no one company has all three,” he said.

Abelson thinks that GM having a stake in Lyft, launching Maven, and last year acquiring AV technology startup Cruise Automation, could be a tipping point in GM’s favor in leading the way in the nascent technology.

“Cruise, Lyft, Maven are all bringing different parts of this singular solution around autonomous on-demand networks in urban environments,” he said.

London Taxi Company Sets Its Sights On Other European Cities

The London Taxi Company is looking to expand its market. The company is owned by Chinese automaker Geely, the same company that also owns Volvo. It has recently completed a $400,000,000 upgrade to the factory where it builds its TX5 plug-in hybrid taxi for use in London. It thinks those cabs, with their wide doors, plentiful interior room, and low emissions would also work just fine in other cities.

The company is looking at such cities as Barcelona, Oslo, Amsterdam, and Berlin. Last week, it took its new TX5 plug-in hybrid to Paris, where concerns about persistent smog are unusually high. Paris recently announced plans to ban cars built prior to 1997 from its roads during week days. Those cars account for only 10% of all vehicles in use in and around Paris, but are responsible for more than 40% of its transportation related carbon emissions. Many of them are diesels with rudimentary pollution controls. Diesels emit particulates and nitrous oxide, both of which are major components of smog.

“Most of the major cities in Europe have an air-pollution problem,” said Peter Johansen, head of the taxi manufacturer. He says limited range “is what has stopped until now the adoption of electric vehicles as the mainstay of taxis.” Since the TX5 is a plug-in hybrid, range is not a concern.

The London Taxi Company is also interested in selling its vehicles to ride sharing services such as Uber and Lyft. “We are offering a global product that will be a global beater,” said Johansen, who says the car can reach European markets even if the UK votes to leave the European Union on June 23, because the country is “so much part of Europe now.”

, London’s cabs aren’t the only ones going green. France’s leading taxi company, Taxis G7, and Uber Technologies now allow customers in France to order electric and hybrid vehicles on their apps. Since December, tourists can also tour Paris in a vintage Citroen 2CV retrofitted with an electric drivetrain.
