The Narrow Channel

This is the sort of project that makes people resentful of cyclists.

A bike channel along the side of a newly reconstructed step street

The bike channels installed on newly reconstructed step streets like this look like a useful upgrade to help cyclists who may have difficulty going around to power up the steep hills. A different design, however, could have been useful for more people, namely pedestrians with carts. 

People struggling to return home with their shopping can easily look at the money the City spent to rebuild their step street, consider the attention given to the needs of other people (the people with bicycles), and easily conclude that nobody cared about their ability to lug their basic necessities home. And they wouldn't really be wrong.

Barriers Against What?

There have been dire warnings recently that car manufacturers might try to exert their influence to take over city streets at the expense of pedestrians (again). A recent flare up followed the suggestion that some executives were considering the installation of gates at intersections to keep pedestrians from crossing against the light and interfering with autonomous vehicles. The backlash from urbanists was immediate: We should not repeat the mistakes of the past when cars were first introduced into cities. People should not be penned in on the sidewalks like cattle. Etc.

A couple of examples:

Caution is warranted, of course. The ability of autonomous cars to successfully navigate dense pedestrian areas is dubious, and some of the materials released by the auto industry have been outright frightening (see below). I agree with the need to be vigilant about the policies that may redesign our cities very quickly, setting new patterns that may hold for generations to come. In this case, though, it seems like a knee jerk response of the "if it's good for cars, it must be bad for pedestrians" variety. The idea surfaced, after all, as a solution to the potential problem of pedestrians interfering with the automated vehicles, which might become paralyzed if people deliberately walk in front of them, knowing that safety procedures designed to avoid injuring people will make them stop.


Nonetheless, I am fairly optimistic that automated vehicles can be leveraged to transform the places we live for the better, and I see crossing gates as an acceptable tradeoff. Likely enough, they could become a welcome addition to our streetscape.

Chronicles of Stolen Space - Pedestrianized Pine Street

This is a designated pedestrian street in Lower Manhattan

The quality of our public spaces in New York City is so much worse than they should be. By all appearances, this is due to a negligent municipal government that has failed to shoulder its responsibilities to safeguard these spaces for public use.

Take for example the case of a pedestrianized block of Pine Street between South and Front Streets. This street was pedestrianized in 1978, yet in recent memory, it has increasingly been used for car parking. It seems that the permission for "service vehicles," clearly intended originally to allow for garbage pickup, provided a foothold for parcel services to use the street for their parking needs. Gradually, others followed suit until the whole space has now become filled with cars.

Two Sides of the Same Woods

On one side of the road, you have tourists reading plaques about trees. On the other, gay men circle the woods looking for potential hookups. The Bronx River Forest is one of the few remaining sections of the great woodland that once covered the New York region. While we tend to consider the plants and animals that populate wooded areas like this as "wild," this landscape is highly shaped by the physical interventions and social activities of humans. It is easy to overlook how much human action can shape the "natural" environment, but the differences created by separate jurisdictional control over trails winding through the woods along the Bronx River on each side of Allerton Avenue create a stark contrast.

People duck under a fallen tree (covered in poison ivy) on the Blue Trail north of 204th Street in the Bronx Forest managed by the Department of Parks and Recreation
Tourists stop along the trail in the Thain Family Forest in the New York Botanical Garden to read facts about the trees 











South of Allerton Avenue, the Bronx River flows through the New York Botanical Garden. Since the 1890s, this land has been City parkland, part of Bronx Park, which is administered by a private institution specifically charged with the development and maintenance of a great living museum. To the north, the parkland is under conventional control of the New York City Department of Parks and Recreation.

There are some physical differences in terrain between the two sections. To the north, the river passes through a floodplain. After flowing into the garden, it quickly drops into a ravine with some moderately steep slopes down to the river. Nonetheless, the main distinctions between these two sections is how the land is managed and access is controlled.

The Road to a Park System for the Future

I drove with my family to Wisconsin and back for Christmas, with a minor detour through Chicago each way. Four days on the road gives you plenty of time to mull things over, and as I passed through the transitions between urban areas and open countryside, kicked in and out of cruise control interacting with the mixture of cars and trucks on the highway, and detoured through Chicago, I found myself thinking a lot about how park systems may look in the future. This may take some explanation, but please come along with me for this ride.

Driving in and out of urban areas is generally just drab. More often than not, buildings become more mundane and spread out, commercial signage grows larger and taller, and then eventually just seems to give up. Most people usually just call it "urban sprawl," even if it's a term without a real definition. But there are a few cities that have great gateways. New York did, once upon a time. Passengers arrived in the harbor by ship, passing alongside the welcoming Statue of Liberty as the skyline took shape as individual skyscrapers continuing to push impossibly higher as you drew nearer. Dramatic as it is to pass through the cut in the Palisades and emerge onto the George Washington Bridge, the city is a mere glimmer in the distance before disappearing into a bewildering tangle of ramps. Likewise, the helix of the Lincoln Tunnel provides impressive glances at the Midtown skyline, but then grinds through a toll plaza and squeezes through the tube before emptying onto congested, nondescript Manhattan intersections.

But Chicago has its moments. We drove along Garfield Boulevard on a side trip going both ways on this trip. Among my strongest memories in life is peering out the window as my cab drove from Midway Airport along the tree lined boulevard on my first trip to Chicago, when I moved to Hyde Park sight unseen to begin college. Exiting the Mad Max world of the Dan Ryan onto Garfield Boulevard invokes a somewhat similar sense of calm and wonder, a definite moment of arrival. Yet while the broad green space and regular spacing of mature trees is still great drama, each time I visit the boulevards on the South Side, the more acutely I feel they have been stripped down to mere scenery. In practice, the boulevards seem to do little to connect any activities between the parks. There is no flowing use of a system of parks, and the roadway design seems to cut off much opportunity. Yet even without the reality of real connective use, the mere vision is compelling and the spacing of greenery contributes to a more legible and enjoyable neighborhood structure. There is much still to be learned and built on from this old Olmsted pattern as our streets continue to evolve.

Rainy Spaces

The city is different on rainy days, sometimes in surprising ways we don't always notice. Light and shadows change their shape. Subway stairs become even more congested than usual as passengers break stride to fight with their umbrellas. Outdoor seating empties out and the doorways in public buildings bustle a bit more.

On first glance, the empty seats in public plazas make these public spaces appear lifeless. It may seem their functions have all been suspended, awaiting the return of better weather. Plazas probably look like fairweather places.




But if you stop for a moment, as you stand in the rain you will see many plazas still serve some use. More often than not, the spaces they form cut corners off the street grid. For everyone rushing to get out of the rain, the plaza is the direct route. Steady streams of fast moving pedestrians course through the plazas.

Of course, as they grip their umbrellas, trying to keep the wind from tearing them inside out, most people hardly notice the shortcut afforded by these little public spaces. They may also be unaware of the effect of the paved surfaces underfoot. Whether they notice or not, the higher quality pavers or flagstones in the plazas provide relief from the drabness of the gray concrete sidewalks, grown darker from soaking in the rain.

On rainy days, plazas do not serve their usual purpose as places to rest or spend time with others. Their aspect changes, but they remain important spaces serving the needs of the public.

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!

Desire Carts

This is not what "walkability" looks like when you watch flashy presentations by planning consultants:

Nevertheless, this is more representative of the lived experience of many communities that actually rely on walking than all those photos of people strolling with their overpriced coffee along cute downtown streets, before getting back in their cars to drive home. These are places where people practice walking for their routine needs. For many people, walking is not a neighborhood amenity, effort to save the environment, or personal fitness choice. It's simply the most practical way to get things done.

That doesn't mean it is easy and convenient, or even always safe. Often enough, people are walking in places that were not planned or designed with pedestrians in mind. Problems notwithstanding, the "walkability" of these places is a fact defined by their very usage.

It is precisely by identifying places where people walk, despite seemingly undesirable conditions, and then observing how they do it, that we can better understand how to make places where people will walk. By focusing on these locations, we also have an opportunity to improve conditions for the people who already depend on walking there while making it more attractive for even more people to join them.

One fascinating indicator of pedestrian activity in suburban-style development is what I refer to as "desire carts." They're odd clusters of shopping carts on the far edges of parking lots. These shopping carts accumulate where people leave them when continuing on foot.

Barricading Sidewalks

This week, the Pope came to New York City, and the NYPD worked hard to keep him safe, along with all those who came to see him. They planned ahead for the challenging logistics of moving perhaps the most high-profile person in the world through one of the world's densest cities, along with all the UN dignitaries who gathered to hear him, together with thousands of visitors hoping to catch a glimpse.

When the NYPD puts effort into something, it gets the job done. There is no question of hard work or commitment to results. The question is the priorities that get the NYPD's attention. While Christian love and police dedication were both on prominent display, the Pope's visit also demonstrated some of the important things the NYPD does not focus on enough. In the face of recurring traffic congestion in New York City, the NYPD is surprisingly nimble at closing entire roadways to keep motorcades secure while avoiding extensive delays for other motorists. As they describe it, they have it "down to a science." What they don't do well, despite decades of increasing attention by the engineering profession, is planning for pedestrians. In fact, most of the people who are affected in every corner of the city are really treated as an afterthought by the NYPD.

For the NYPD, when it comes to major events, pedestrians often seem like little more than obstacles to the motorcades. When the NYPD does turn its attention to the people trying to walk around, they seem to be taken into consideration only as crowds to be "controlled," or as "security threats" to be surveilled or excluded. If only a fraction of the attention paid to moving concrete blocks for cars and placing snipers on roofs was applied to maintaining appropriate sidewalk widths, the city would probably be safer. It would certainly be more orderly and comfortable.

Let's consider how NYPD leadership discussed its preparations. Posing for photos in front of a vast lot filled with parked police cars, the Police Commissioner bragged about "1,173 police cars, 818 tons of concrete barriers and 39 miles of metal and wood barricades" that were prepared for the Pope's visit to New York City. The department's twitter account followed up, highlighting the massive amounts of material they stockpiled around town. This neatly summarizes the NYPD's priorities: setting up barriers and moving motor vehicles.

Emerging from Residual Space - Bikes in Battery Park City

A couple recent lunchtime walks through the older corner of Battery Park City illustrated the rich interactions between residual space and emerging uses. Where bicycles were once tucked away into back corners, they are now poised to redefine the cityscape.

Battery Park City is an interesting neighborhood enclave for myriad reasons. Its character as an enclave results in part from its origins as a recent, master-planned community controlled by a State authority. Yet this character is due even more to its separation from the rest of Lower Manhattan and access to the subway system by the West Side Highway (aka West Street and Route 9A). Yet while this highway isolates or insulates (depending on perspective), it also adds another layer of transportation that helps to shape the character of Battery Park City. The Hudson River Greenway runs along the West Side Highway and connects directly into Battery Park City, providing residents and workers quick and easy bicycle access to much of Manhattan.

Gateway Plaza is the oldest apartment complex in Battery Park City. The brutalist architecture and organization around a parking garage and interior access street predate the reorientation toward more traditional urban form under the Cooper Eckstut design guidelines. A central space encircled by the access street provides a landscaped pedestrian area. As demand for bicycle parking has grown, this central feature has been preserved by maintaining it off-limits for bicycle parking, while the less significant scraps of space have overgrown.

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 
when driving past the bus stop

Poor Scoping Leaves Residual Space

It is encouraging to see New York City developing more sustainable stormwater management. Unfortunately, the recent bioswale constructed on Bronx Park East at Pelham Parkway earns a grade of "D" as an urban infrastructure project. Poorly scoping the project left residual spaces and diminished functionality, which will ultimately be more expensive and disruptive to address later.

The bioswale detains storm water that would otherwise increase combined sewer overflows
The hatched area to the right probably could have been unpaved as well

The hatched area at this end is also useless, leftover space
It should be an active space as a refuge island as part of the greenway connection

Gas Stations as Corner Stores

Planners talk about the mythical corner store. It is generally accepted wisdom that residents should all have a place within walking distance where they can buy that virtuous "quart of milk." Yet, ironically, it is often the very same planners who are hostile toward the businesses that actually serve this role in many communities throughout the country: gas stations.

Sit and watch for a while, and you will see some interesting things at many neighborhood gas stations. Interestingly, at such quintessentially auto-oriented businesses, there is often a surprising amount of pedestrian activity.


In many existing communities throughout America, I have seen more walking trips to gas station convenience marts than anywhere else in town. Even in some dense city neighborhoods, I have observed gas stations filling a role where urban poverty has left residents with few retail options. This is much more an indictment of poor overall development patterns than a recommendation for gas stations, yet improving existing places requires dealing with them on the terms of their actual assets. Bemoaning deficiencies does not build up a place.

Seeing Differently by Traveling Differently

The way people perceive space differently based on the way they move through it has long been a fascinating topic. It is a rarity these days that I have a moment to put such observations into any kind of order, but the topic has surfaced for me twice in the past month.

The first was a realization of how differently Van Cortlandt Park in The Bronx is seen by drivers on the Major Deegan Expressway and those who follow the Old Croton Aqueduct Trail:
Then the other day, @TransitSleuth had a quick series of tweets observing differences between people driving and those riding a bicycle when their route was disrupted:







 Common to both sets of observations is a richer level of detail at slower speeds and the narrowing of focus to the needs of operating the vehicle while driving. There are a few hypotheses to ponder with the tweets by @TransitSleuth, and it is a regret I lack the time and resources to undertake some rigorous research.

Hypotheses on factors that may allow cyclists to identify routes to divert around roadway closures better than drivers:

  1. Cyclists tend to take shorter trips. Therefore, they are more likely to be in familiar, home territory when encountering a roadway closure.
  2. Vehicular queuing prevents drivers from approaching the incident as closely. Therefore it is harder to identify the specific network links that are closed and need to be circumvented.
  3. Higher operating speeds narrow the peripheral vision of drivers. As a result, they have not benefited from views down sidestreets to develop as much awareness of parallel routes.
  4. Cyclists must engage in more trial and error to optimize their routes, which provides them with awareness of their alternate routes. Whereas arterial streets generally offer routes optimized to meet the needs of drivers, cyclists often must travel different alternate routes before determining which path best meets their needs for travel time, safety, and other factors. 
  5. Mode selection reflects attitudes toward time and speed. People who choose to travel by bicycle demonstrate a lower priority toward speed and a greater willingness to spend time on their trips, which would are traits that would also make them more likely to periodically explore alternate routes.

Of course, I can't really say to what extent any of this speculation is actually true. Perhaps I will have the good fortune of stumbling onto an academic who takes an interest. It would make for some great studies.

Filling the Void, Maintaining Sight Lines

When cars park too close to the corner, drivers and pedestrians often cannot see each other well enough to make safe decisions. To correct the problem, parking is frequently prohibited near intersections to improve sight lines, a practice sometimes referred to as "daylighting." Nevertheless, regulations cannot actually prevent the hazardous conditions from continuing. The public and even some enforcement agencies seem to have a low level of awareness or appreciation for the need to keep these locations clear, and the residual nature of these spaces continues to be problematic.


In an effort to improve the situation, enhanced markings are often used to reinforce the regulatory signage. Even with this effort to emphasize the regulations and create some illusion of occupancy, the space continues to feel unused. In an active urban environment, a space marked off for the sole purpose of a sight line really is, in practice, underutilized. The demand to make more intense use of it is probably inevitable.

The solution to these residual spaces is to provide them with uses that do not compromise the sight lines. To be effective and persuasive enough to continue installing them elsewhere, treatments must embrace uses that are appealing to the community.

The classic response is to install a curb extension, sometimes called a "neckdown." These rely on the curb as a physical barrier that effectively discourages parking. They also provide benefits for traffic calming and shortening crossing distances for pedestrians. A curb extension is an expansion of the sidewalk, creating more usable space for pedestrians, although they may recognize relatively little value in the extra panels of concrete. This solution is often complicated, though, by mundane engineering details like drainage or even traffic signal location. Capital costs can discourage or delay construction.

Where Is the Plaza at Bay Plaza?

My family ends up out at the Bay Plaza shopping center in Co-Op City on a somewhat regular basis. Cinemas are becoming few and far between in The Bronx, and the AMC at Bay Plaza is one of our best options for a date at the movies. Despite all the drawbacks of the sprawling strip mall environment, it also remains one of our more convenient shopping alternatives for some needs. Like many others who frequent Bay Plaza, we get there by bus.


Unfortunately, the good money spent on bad design in Bay Plaza does not create a positive sense of place. It just makes transit passengers and the pedestrians from Co-op City feel second class. It makes the place less attractive and functionally inferior for shoppers who arrive by car as well.

There is no coherent network for internal pedestrian circulation.  Everything has been designed to move cars in and out of the parking lots, resulting in sidewalks that are narrow and often disconnected, as well as poorly designed crosswalks.  The transit stops have been dropped in as an afterthought, and are further challenged by their location on private property. Even for those who drive, getting between stores, restaurants, and entertainment is not particularly pleasant. Bay Plaza has put some attention into its landscape architecture in recent years (although there is room for great improvement for stormwater management with the endless acres of pavement!), but what it actually needs is an urban designer.

Nice landscaping.
Where's the sidewalk?

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.

"Urban Triage" on Our Streets?

With the number of pedestrians and cyclists who get killed on our streets every year, you might think that "Urban Triage" was a reference to the aftermath of vehicular violence. It sounds like it could be part of New York City's "Vision Zero" campaign. Instead, it is a term Jeff Speck uses in Walkable City. He attributes the phrase "Urban Triage" to his mentor, Andres Duany, and he recommends it as a way to determine which streets are deemed worthy of saving. The idea is that resources are limited, so projects should be focused on the streets that have the most potential:
Only the "in" streets are to receive walkability improvements like safer traffic patterns, street trees, and better sidewalks.
Before I sound too critical about Speck's recommendations for prioritizing downtown streets, I want to emphasize that Walkable City has been very effective at sparking public interest around the need to design streets that support pedestrian activity. My views align with Speck's far more than they diverge, especially in the earlier portions of the book where he synthesizes many of the current efforts underway around the country and beyond to understand and improve pedestrian conditions. Overall, it has been very positive that Speck has brought so much attention to the need to improve pedestrian conditions and put real effort into developing active transportation networks.

Nevertheless, as Colin Dabkowski in Buffalo recently noted, there are some real problems with Speck's approach. Dabkowski is right that social equity needs to be at the forefront of our efforts to improve cities, and he is right that Speck's writing does not lead the discussion in that direction.

Speck posted a response, where he claims that these concerns are unfounded, that his critics simply failed to understand him. Speck's tone is dismissive (he accuses Dabkowski of not fully reading his book), but Speck's response ends up reiterating some of the basic problems with his planning approach.

Growing Public Space from Grove Street

There is some exciting news that Jersey City may extend the public space from the plaza at the Grove Street PATH station further up Newark Avenue.


The plaza at the Grove Street PATH station


The existing plaza has already closed the easternmost block of Newark Avenue to traffic. Closing another block to traffic could make Newark Avenue part of an emerging trend of converting historical main roads into pedestrian space. The new plazas in Times Square are the prime example. Dating back to pre-colonial times, the trail that became Broadway was the main route up the island of Manhattan and beyond. Over time, its importance as the main traveled way waned as other routes were designed and constructed to standards more specifically meant to move vehicles, while local activities continued to crowd onto Broadway. Today, at Times Square, Broadway has been interrupted as a traveled way entirely. The social activities have asserted themselves as a place and the land has been converted into public plazas.

Streets experience a continual conflict between going and staying. Strips of land are transformed into active ways through the practice of travel, but the travel activities must push aside other uses that might utilize the space. Roads have been characterized as non-places. This is appropriate in a way, since places are spaces where people stay. The road or street is the space people use to leave.

Those Old-School Traffic Engineers

It has become popular to indict traffic engineers of yesteryear as men so determined to move cars more quickly they disregarded the safety of pedestrians just trying to get across the street alive. This criticism that they were anti-pedestrian is an uncharitable view. It ignores the historical record, unfairly excluding their deliberate attempts to improve pedestrian safety. So in the words of Al Smith: Let's look at the record.

To illustrate this, we don't have to look any further than the language commonly used to criticize the engineers who designed one-way streets decades ago. Consider this example, which is typical of comments made by many observers of streets (who are well intentioned and otherwise often well-informed):
The city's avenues were converted to one-way for one reason only: to give the city's driving elite priority over its walking majority.
