America’s Worst Traffic, And What To Do About It

February 25, 2010 | 3:16 pm

New York traffic mapWe’ve just published a neat set of maps on Forbes.com that highlight America’s worst traffic chokepoints. The situation in New York, illustrated at left, should be familiar to anyone unfortunate enough to own a car in the area. The Cross Bronx Expressway, one of the great urban planning disasters of the late 20th century (and the subject of some really excellent exposition in The Power Broker by Robert Caro), has the worst single traffic tie-up in the country, as well as several others among the top 10.

The data that the maps are based on come from my friends at Inrix, a clever company based just outside of Seattle that measures traffic congestion using data from GPS tracking systems in commercial fleets. I’ve written about them before, and used their data in December 2008 to form the Forbes Chirp Index,” a group of leading indicators with which we (fairly accurately) predicted that the recession would bottom out late in the summer of 2009.

After a couple of years of declining traffic congestion (due first to rising gas prices and then to rising unemployment), traffic congestion seems to be coming back. Growth in economic activity and stimulus-related road construction projects are bringing more people onto the roads and then slowing them down.

A minor tiff erupted in the comments section of my article; one commenter suggested that traffic congestion wouldn’t come back if only we invested more in public transportation. The next commenter wrote that public transportation hasn’t been proven to have any meaningful impact on traffic congestion.

Both commenters make legitimate, though incomplete, points. Public transit advocates tend not to talk of payoffs from transit investment in terms of immediate relief from congestion; after all, much of the housing and commercial space that’s been built in this country over the last 50 years is fundamentally incompatible with efficient transit schemes. The office-park worker who lives on a cul-de-sac will likely never be able to use even the most ambitious new transit system to commute–at least not as long as he lives in a housing tract and works in an office park.

That’s why transit advocates concede that new rail lines won’t immediately cut traffic on adjacent arterial roads. Rather, they say, transit systems encourage the kind of development that is compatible with transit use: walkable neighborhoods with a combination of townhouses, apartment high-rises, offices and shopping that are based around transit stations.

This kind of development is popular in places like Northern Virginia, where a well-run rail system links outlying areas to a massive job center in Washington, D.C. It takes much more patience to introduce these kinds of transit-oriented neighborhoods to cities with comparatively weak central business districts, like Phoenix, Los Angeles, and Atlanta, since people who live in them but don’t work in them may still have to drive to otherwise-inaccessible office parks.

So new transit networks in car-oriented areas constitute major investments in reorienting urban development over a period of decades, not a quick attempt to remove a few cars from highways. Traffic will come back this year–there’s no way around that–but sound investments now could mean that it will bring fewer headaches fifty years from now.

New Jersey 7: George Washington Bridge

June 26, 2007 | 2:35 pm

The G.W.B. doesn’t disappoint. It’s really big—the roadway is almost a mile long and is suspended more than 200 feet above the surface of the Hudson River—but it’s also digestible. Walking across it doesn’t take terribly long, and it’s actually a bit easier than the walk across the Brooklyn or Manhattan Bridges, since the deck links a high point in New Jersey to a high point in Manhattan.

The day that I took this walk, the south sidewalk was closed, so I used the walkway on the north side of the bridge. The natural scenery up the river is just as magnificent as the man-made scenery downriver.

From the metro area that gives us such names as Hoboken, Weehawken, Hackensack*, Harsimus Cove and Throgs Neck, comes Yonkers, which sits across the city line from the Bronx. It’s visible from the bridge.

The Cloisters, part of the Metropolitan Museum of Art, sits on the top of a hill in Fort Tryon Park at the very northern tip of Manhattan. Its tower pokes through the trees in this photo. Below it, just above the shoreline, is Robert Moses’s Henry Hudson Parkway. In The Power Broker, Robert Caro’s biography of Moses, the construction of the Henry Hudson Parkway was where Moses went from arrogant-but-generally-good to essentially maniacal (but there were signs earlier, of course).

The views of Midtown are as good as ever, of course. The scale of the Empire State Building is, I think, best appreciated from this distance, where it still overpowers just about everything else.

As we cross over the Manhattan shoreline on the bridge, we can see railroad tracks below us. These were originally built by the New York Central to gain access to the West Side (its Grand Central Terminal is on the East Side). Now they’re owned by Amtrak, which uses them for trains to Albany and Chicago. These tracks and the environment around them in the early 20th century inspired Robert Moses to pursue public works in the first place. When he built Riverside Park and the Henry Hudson Parkway, the tracks were the source of much of his funding, part of which came directly from the New York Central and another chunk of which came from Federal funds earmarked for the elimination of railroad grade crossings.

Upon arriving in Manhattan, we’re greeted by the sight of the George Washington Bridge Bus Terminal (in the foreground). Behind it are residential towers that are located directly on top of the Cross-Manhattan Expressway segment of I-95.

And now, a final view of the bridge.

The tour is over. The A train whisks me back downtown, and safely home to Park Slope.

New Jersey 4: Trashy Stuff Along the Way

June 26, 2007 | 2:20 pm

The ride has some other minor attractions.

Back between Jersey City and Hoboken, the light rail trains pass this stop, which really ought to be announced by a recorded pirate voice:

After leaving Hoboken Terminal, and just as they pull out of the Lincoln Harbor station, where I disembark, the light rail trains pass beneath the “Helix”, a curved causeway that brings Route 495 off of the Palisades and down into the Lincoln Tunnel. The views from the Helix are spectacular.

Lincoln Harbor is a drab, sterile development that includes a marina, a couple of strange housing/something-else piers, and a blue office complex that includes this gem of a food court:

But at least this is where the bus stops, and it’s on time. Route 158 follows River Road up the narrow plane between the Hudson and the Palisades. Good views of the west side of Midtown are off to the right the whole way:

The road has been developed quickly over the last few years, and there’s now a great deal of expensive, low-quality housing crammed in between it and the river.

Condos start at $600,000 in “Grandview II at Riverwalk”, and the developer, K. Hovnanian, promises “an enticing shopping promenade” in the neighborhood. But the commercial options in this area are bland strip malls like this one, which turns its back on Manhattan’s Upper West Side and the tower of Riverside Church.

But not to worry. There’s something pretty neat coming up.
