Staring at the Pole

I was recently at Frederick Douglass Circle at the northwest corner of Central Park. Every time I go, I am bothered by a detail that detracts from the relationship between the plaza and its surroundings. I am not sure if the detail was on the drawings I first say many years ago, but if it was I certainly missed it.

Back in 2003, I attended a public meeting for neighbors skeptical about the transformation of Frederick Douglass Circle into a public space. At the conclusion of years of participatory planning and a design competition, residents of Towers on the Park emerged with last-minute objections to various aspects of the reconfiguration of the previously dysfunctional intersection (the circle was previously cut through by traffic, creating far too many movements as well as lane drops in the middle of the intersection...). I spoke in favor of the project, convinced it would create a great new public space.

Then construction stretched on for many years. It was disruptive for everybody in the area and continued long beyond what any resident would consider reasonable. I second guessed myself for speaking up after seeing the ordeal I had helped to put these people through. I hoped the quality of the built space would eventually make up for the disruptions in so many lives.

Since the first time I was finally able to visit the plaza some time around 2011, I have been bothered and deeply disappointed. For me, the execution of the concept was seriously compromised by one poorly placed traffic signal pole.





The overall concept for the plaza was strong, and much of it has in fact turned out very well. It would be unfair to call this urban space a failure. Yet while the statue of Douglass was symbolically positioned to face Harlem, the gesture is undermined by that traffic signal. Instead of looking up the avenue that carries his name, Douglass just stands there staring at a steel pole a few feet in front of him.

Chewing Gum on a Sign 15 Feet Over the Street

Stuck on a sign hanging over Broadway, out of sight of the throngs of workers and visitors crowding the sidewalks and unnoticed by the drivers passing below, are a lot of pieces of chewing gum. There's a few stickers stuck on there too. While generally invisible to ordinary New Yorkers, it is a shared experience of the thousands of tourists who pass mere feet below the sign while seated on the top of a double-decker bus. Some of these tourists are the people sticking the gum on there.




There are a handful of places where people have collectively created a kind of grotesque landmark by sticking their chewing gum onto something. The old gum tree in South Philadelphia and more extravagently, the gum wall in Seattle, come to mind. Compared to those, this sign is thoroughly unremarkable. Yet it shares the same fledgling crowd dynamic. All these locations emerge because something prompts others to follow the example of that first person who deposited their gum in an inappropriate place. At first, others just take enough notice to take advantage of the opportunity to discard their stale gum, until it reaches a critical mass and presents itself as an invitation to join the fun. In this case, it's possible to identify how this sign developed into the early convenience phase.

Is There a "One-Way Epidemic"?

Recently, City Limits ran an op-ed by architect John Massengale about the need for safer street design. Under the photo at the top, the caption read: "First Avenue in Manhattan. Avenues used to run two-way, which is safer for pedestrians, but were mostly made one-way, to make life easier for drivers." This argument was elaborated in detail in the text. This week, Cap'n Transit followed up on his blog, extending the campaign against one-way streets.

These are familiar arguments. After beginning a discussion a while ago about one-way streets, it was suggested that I refer to "The One-Way Epidemic" section in Walkable City, which makes these same claims. These pieces all serve as good examples for discussion purposes. I wholeheartedly agree with the need to redesign New York City's streets to be safer for pedestrians, and I share the majority of the views of these safe-street advocates. I find some areas of common ground regarding one-way streets, as well, but it is useful to draw out the key differences as well as the overlap to illustrate why the rhetoric against one-way streets is overblown and counterproductive.

Let's start with the term "epidemic" used in Walkable City. This is rhetoric that invokes fear. The book explicitly compares the creation of one-way streets with an outbreak of influenza that killed 20 million people in 1918-1919. The not-so-subtle claim is that one-way streets are an imminent threat to your life. Avoid them like the plague!

The Tremont Crash Zone

A passenger waits for the bus at a stop where the sign has
been wiped out by an out-of-control vehicle. Apparently
crashes are so common here, extra protection has been
added around the posts for the traffic signals
When New York City reduced the citywide speed limit from 30 to 25 mph, some arterial streets kept the higher speed limits. Among those was a portion of East Tremont Avenue. On recent visits, it looks like an outright crash zone. An entire stretch of the street east of Morris Park Avenue has been rendered a sprawling residual space by the combined impacts of out-of-control cars, shallow properties bordering the railroad, and the proliferation of auto-related land uses. Given the conditions confronting pedestrians, the speed limit warrants a revisit.
This sign encourages higher speeds

Conflicted Crosswalks: Hudson St and Christopher Columbus Dr

The intersection of Hudson Street and Christopher Columbus Drive in Jersey City has real potential to someday become a great public space at a lively, multimodal intersection. For now, it is a fragmented set of residual spaces with a traffic design that is inconvenient and uncomfortable for pedestrians and bus passengers. This is a case where excess concern about pedestrian-vehicle conflicts, combined with decisions to prioritize motor vehicles and a failure to realize that vehicular volumes never materialized, has resulted in a compromised pedestrian network that simply does not work properly. Let's look at how we can put it on a path toward realizing its potential.



This irregular intersection has only modest conflicts between pedestrians and vehicles. That is largely because the vehicular volumes are really quite light. Nevertheless, at this set of intersecting roadways, pedestrians are instructed to follow an extraordinary detour across several different crossings to avoid the potential conflicts with turning vehicles. To further the inconvenience, one of the crosswalks on that detour route has an unusually short pedestrian signal time.

This poor treatment of all the pedestrians who walk through the area is unnecessary, and it sets the wrong priorities by favoring motor vehicles. The whole confluence of intersecting streets should be reevaluated, and in the process it should be possible to create a whole new public space.

The crazy detour really is unnecessary. The conflict this whole situation was designed to avoid is so minor, it really seems unusual that the crossing was prohibited at all. Typical intersections throughout Jersey City and just about everywhere else have worse turning conflicts than this. With a close review of the signage that has been installed, the motivation can be discerned, but the aspect of the design that raised the concern is not only unnecessary, it creates a risk of vehicular collisions.

The pedestrian crossing is prohibited at this location because southbound Hudson Street has two right turn lanes.

The vehicles turning from the second lane would pose a real threat to pedestrians crossing the street, so in an attempt to maintain safe conditions for the pedestrians, the engineers attempted to remove them from the mix.

Despite the efforts of the engineers, the pedestrians who frequent this location exert their independence and continue to cross illicitly. By and large, they have little difficulty. Nevertheless, the apparent conflicts should be resolved, and can be resolved in a way that is much more satisfactory.

Conflicted Crosswalks: Gun Hill Road and Webster Avenue

This is the first of a series of posts about crosswalks with conflicts that threaten pedestrians. These are intersections located in neighborhoods that are not living up to their full potential, due in large part to traffic that is hostile to walking. As they exist today, these street corners are not neighborhood places; they are merely the residual space where flows of vehicular traffic collide. Each intersection has its own unique problems, but looking at several cases will help to identify some commonalities. The first intersection we will review is Gun Hill Road and Webster Avenue in The Bronx.

This is an intersection that periodically injures pedestrians, sometimes fatally. Taken as an absolute number, the accidents are on the high side but may not stand out as a priority. However, after considering that the total pedestrian activity is quite low, it becomes apparent that the actual crash rate is particularly high and clearly indicates a problem. (A deeper review would indicate that the unsafe intersection is a major factor in suppressing pedestrian volumes, as people avoid the intersection and trips between the neighborhoods altogether for fear of being hit by a car!) Pedestrians crossing Webster Avenue on either the north or the south side encounters real problems with left-turning vehicles.
