DOT to Propose Radical New Traffic Plan for Park Slope

Park Slope’s Fifth Avenue: a pedestrian- and bike-friendly, two-way, neighborhood Main Street.

New York City’s Department of Transportation is getting set to propose a major change in the way cars and trucks flow through the avenues and streets of Park Slope, Brooklyn.Sources say that the plan will include the following:

  • Fourth Avenue, a major six-lane artery with left-turn bays and parking lanes, will be narrowed. The center medians will be widened.
    Sources say that the City’s Fourth Avenue plan may pull some elements from Alexander Garvin’s 2006 Master Plan.
  • Seventh Avenue, a neighborhood commercial strip, will be transformed from a two-way to a one-way.
  • Sixth Avenue, a residential street, will also be transformed from a two-way to a one-way.

The new traffic plan was unveiled by Deputy Commissioner for Traffic Operations Michael Primeggia at Brooklyn Borough Hall recently. Though details of the plan have not yet been released, at first glance, DOT’s proposal runs completely counter to community-friendly transportation planning being done outside of New York City.

As USA Today recently reported, hundreds of U.S. cities and towns are "switching one-way streets to two-way to improve commerce downtown,
according to the American Planning Association in Chicago. The trend
got rolling in the early 1990s and has expanded this year to bigger
cities such as Miami, Dallas and Minneapolis."

Engineers and planners specializing in the practice of traffic calming and the development of pedestrian-friendly neighborhoods generally advocate the opposite of DOT’s plan. That is why many cities and towns are converting their 1950’s-era multi-lane, one-way, through-traffic streets back to slower, more locally-oriented, two-way streets. There are three reasons why traffic calmers believe two-way streets are better for neighborhood life:

  • One-way streets generally have higher motor vehicle capacity than two-way streets. Increasing a street’s capacity induces more driving. 
  • One-way streets generally serve through-traffic first, local traffic second. One-way streets are oriented towards serving people driving through the neighborhood rather than people who live, work, shop, walk and bike in the neighborhood.
  • While one-way streets can simplify crossing for pedestrians who only need to look in one direction, and some studies have shown that one-way streets tend to have fewer pedestrian crashes, one-way streets generally have faster vehicular speeds
    than two-way streets, making crashes deadlier and more destructive. 

The higher speeds on one-way streets "creates new problems," according to the Pedestrian and Bicycling Information Center. That is why many cities are "returning one-way streets back to two-way to allow better local access to businesses and homes and to slow traffic. Two-way streets tend to be slower due to "friction," especially on residential streets without a marked center line, and they may also eliminate the potential for multiple-threat crashes that exists on multi-lane, one-way streets."

The USA Today article provides some interesting historical background on the one-way / two-way phenomenon:

The boom in one-way streets began with the Cold
War in the 1950s, when cities planned quick routes out of town for
evacuation in case of nuclear attack,
says John Norquist, one of the
first vocal advocates of two-way-street conversion. Norquist was mayor
of Milwaukee from 1988 to 2003 and now runs the Congress for the New
Urbanism, which promotes the revitalization of cities.

The growth of the suburbs contributed, too, as
cities smoothed the route home from work,
says Neal Hawkins, associate
director for traffic operations at the Iowa State University Center for
Transportation Research and Education. Now, though, there are more jobs
in the suburbs, more entertainment downtown, and drivers go in all
directions.

    ABG, it sounds good to me. I sent Eliot a note.

  • Susan B,
    A one-way street doesn’t have to be a speedway, and all those things you suggest are good measures. However, the DOT is proposing this in order to make it a speedway. That’s all they know, and they’re stickin’ to it. Until we see otherwise (and they add all the traffic calming measures we want), please don’t encourage one-way streets in NYC.

    Several blocks on 6th avenue are closed for annual block parties. If it becomes a one-way thorofare with buses, it doesn’t sound like we could ever have block parties again.

    I wish that they would really do something to address the speed of traffic on 8th Ave during non-rush hours and the horrible bottlenecks at rush hour. I live on 8th and the honking I hear all morning is almost unbearable – it gets no one anywhere, anytime faster and yet people lean on their horns endlessly. A plan by DOT should not be developed without attention to quality of life issues for residents – is anyone paying attention?!

  • lee

    they should do something to prevent cars on union from blocking the intersection with 8th ave. in the am. maybe a red light camera and issue summonses. I think that, along with double parking, is the cause of much honking.

    during non peak hours the lights should be set in an alternating pattern, and not in a progression precisely to prevent people from speeding by making them stop every 4-5 blocks.

    The nypd should give speeding tickets to people doing 50mph to beat the alternating pattern.
