A barging garbage truck, a slippery Greenway - and why New York's bike routes are like a 747

It was far from being the most dignified manoeuvre I’ve ever made on a bicycle. Around 9.25am on January 29, as I rode to work down Prince St in lower Manhattan, I heard a garbage truck approaching me from behind, its driver blaring the horn. Since the bike lane was still full of snow and I was in the middle of the street’s single travel lane, I was immediately in the vehicle’s path – and fearful the driver wouldn’t stop before hitting me. I pulled over into a clear patch of the bike lane, jammed on my brakes and apologised to the cyclist following me for pulling across her path. The garbage truck careered past.

The next morning, chastened by my experience and with fresh, light snow falling, I decided to mix with motor vehicles as little as practicable, to ride over the Brooklyn Bridge, through TriBeCa and up the Hudson River Greenway, which had been well cleared of snow the night before. But, when I pulled onto the Greenway, I found there had been no new treatment following the light overnight snow. I rode very gingerly uptown, worrying that the layer of slushy slow would cause my tyres to lose their grip.

The two experiences encapsulated the challenge that even I, a fairly hardy cycle commuter, face when trying to get around a city by bicycle, especially in winter. I need a network of viable routes I can follow to get places. I’m more likely than many people to regard a route that includes jostling with motorists or that isn’t marked as a bike route “viable”. Yet people unused to city cycling or in areas with poor infrastructure probably spend most of the time feeling the way I do when there’s snow and ice about. It’s as if the subway offered a choice of only highly circuitous routes or routes that stop every few blocks and required one to walk.

the network
The realisation explains a fundamental disconnect I’ve noticed in perceptions of New York’s efforts to boost cycling. I regularly hear from cyclists in other places – particularly London – who’ve seen pictures of New York’s flagship cycle infrastructure projects and been impressed with the city’s apparent commitment to boost cycling. Few accept my reply that, since only 1 per cent of commuter trips in New York are by bicycle, the efforts are at least partially failing. “At least it’s better than we’ve got here,” they tend to reply, gazing longingly at pictures of the Prospect Park West bike lane or Allen St.

Still fewer correspondents contacting me from London accept my follow-up point. Although London currently lacks many showpiece, well-designed facilities to match the best in New York, I point out, 4 per cent of commuting trips in London are by bicycle. There is clearly some aspect of cycling policy in Londonbedevilled as it has been by a lack of boldness and a reliance on dubiously effective road markings – that has proved vastly more successful than New York’s approach. The question is what’s making the difference.

if you know where to find them
The answers, of course, don’t lie entirely in road layout. London has, for example, the Central London congestion charge, which over the last 12 years has sharply cut the numbers of vehicles entering Central London daily. Thanks partly to Sheldon Silver – the recently-disgraced former speaker of the New York state senate – New York lacks such a mechanism to keep through traffic out of lower Manhattan.

Public transport in London is also far more expensive than in New York, making a switch to cycling far more attractive financially.

London’s streets are, in addition, far safer than New York’s, even if that’s damning London with faint praise. For 2013, the last full year for which figures are available, there were 294 road fatalities in New York, which has a slightly lower population than London, including 168 pedestrians and 10 cyclists. In London in the same year, there were 132 road deaths in total, including 65 pedestrians and 14 cyclists. London’s far higher cycling rates make it clear that it’s a far safer place to ride per mile travelled than New York.

Yet one of the biggest parts of the answer, I’d suggest, can be found in thinking about the fate of the Boeing 747. The jumbo jet, hugely successful though it has been, faces phasing out at least partly because it was designed for an era when airlines sought consistently to operate “hub-and-spoke” services, feeding traffic from around a given region into a hub. Passengers would be transferred at those hubs onto long-haul flights on airlines’ hyper-efficient 747s.

but be sceptical this picture tells the whole story
The jumbo is suffering partly, analysts say, from improving efficiency - the biggest 777 aircraft can carry pretty much as many people with just two engines. But it is also losing out to aircraft such as the Boeing 787 and Airbus A350 that can fly long distances but are far easier to fill up. It’s much simpler with such aircraft to offer passengers direct flights from the city where they’re starting out to the city on another continent where they want to go. It turns out passengers don’t crave the excitement of running to transfer between flights at big hub airports, worrying whether their baggage is being treated with the same urgency. There's a growing preference for going the lowest-stress, most direct route.
 
New York, I’d suggest, has done an excellent job of sorting out a few key hubs for a network – protected lanes up Allen St and along Sands St sorting out some of the trickiest approaches to the Manhattan Bridge, for example. There’s a protected bike lane along Prospect Park West funnelling cyclists through Park Slope. There are bike paths along parts of the two sides of Manhattan. New York has provided the Atlanta-Hartsfield or London Heathrow type hubs and some of the routes that link them. But the system features too many disconnects – too many frantic dashes across the system’s gaps – to offer a full range of comfortable, point-to-point journeys.

First Avenue’s bike lane – often praised as a good example of recent improvements – disappears suddenly for 10 blocks (or half a mile) between the United Nations and 59th Street, pitching cyclists into chaotic motor traffic climbing towards the Queensboro Bridge. Worse still, anyone who has successfully cycled to the Upper East Side and is wondering how to head south again will find not even a painted bike lane for more than three miles on 2nd Avenue between 100th St and 34th St. The 8th Avenue bike lane disappears for five blocks around the Port Authority Bus Terminal, the chaotic point on the trip where cyclists are most in need of protection. The 9th Avenue bike lane disappears for a couple of blocks around Penn Station. There are more.

Instead of a network, New York has built a series of sections of bike lane, with noisy objections to the loss of parking or some other complexity keeping the sections all too often separate from each other. The regular changes in colour of the routes on the city’s bike map – indicating a change from a protected lane to a painted lane, to mere “sharrows” then back – are testament to New York officials’ weakness in the face of noisy, local protest. Perhaps the emblematic failure relates to the Hudson River Greenway. It’s one of the safest, most comfortable to use bike facilities in the city. But nearly every means of accessing it south of 59th St involves a suicidally dangerous manoeuvre amid lines of fast-moving cars seeking to reach the West Side Highway.

It’s little surprise that, presented with confusing routes that disappear in the most dangerous places, relatively few New Yorkers are taking up the invitation to start cycling.

When I lived in London, by contrast, my head was full of the routes – often complex and roundabout, admittedly – of the London Cycle Network. The LCN – now out of fashion, since its introduction was overseen by Ken Livingstone, the former mayor - follows routes mainly along back streets across the city. It is so comprehensive that, by the time I left London, I could do 30-mile round trips on it without consulting a map. London’s existing Cycle Superhighways – appallingly designed as most are – at least seek to provide routes that take people to places. Both reflect what seems to me a greater tendency on the part of London’s planners than New York’s to think in terms of routes, not isolated projects.

of London's cycling networks

This week’s decision by Transport for London, the London mayor’s transport body, to go ahead with a comprehensive network of segregated bike paths should make the position far, far better. Unlike New York’s rather disjointed system, they should act more and more like the most efficient networks – like metro systems that draw commuters in from distant suburbs into heavily-used, highly-efficient core areas or express parcel networks. Such networks’ strength is their comprehensiveness – well-planned new metro lines generate disproportionately high numbers of journeys because they unlock new point-to-point journeys both on the existing network and the new line. London’s networks, at least in theory, aim to provide a reasonably consistent journey for a high proportion of the trips in the city that are possible by bicycle.

the "infrastructure" that made me once
doubt infrastructure was the answer
Not, of course, that the simple dichotomies are the whole story. London’s cycle planners are, I know, prone to some of the same shortcomings as those in New York. I so despaired when I lived in London of the dire quality of much of the existing cycle infrastructure that I preferred an approach that sought to make onroad cycling safer. The roundabout, backstreet routes I often used are so circuitous that many simply won’t use them. In thousands of rides past South London’s busy Elephant & Castle interchange, I took one of the avoiding routes off the main roads every single time. To many other people, that route is so painfully slow that they prefer the main roads, where there are regular deaths.

New York’s project-based approach has at least improved some of the biggest barriers to cycling, even if it has always joined the bits together. I find the experience of mixing with fast-moving traffic on multi-lane New York streets sufficiently scary that I welcome any relief from it. I also understand, given the challenges of getting anything meaningful done in New York, why Janette Sadik-Khan - the city’s former, much missed, transportation commissioner – focused so hard on some flagship projects. The projects have proved resounding successes – had she sought to turn the projects into perfectly-realised networks, she could easily have become bogged down in the bureaucratic malaise that seems to have swallowed Polly Trottenberg, her well-meaning successor.
 
Copenhagen: an acutal cycle network, in magnificent action
Nevertheless, New York currently risks, it seems to me, watching from the sidelines as London’s new network of protected routes turns the city’s existing provision into a still more successful network. It’s hard to imagine New York’s achieving anywhere close to its target of having 6 per cent of trips by bikes by 2020 until it starts taking the challenges of providing a real network seriously.

Ms Trottenberg may be about to start tackling the issue in earnest, even if her department's record of retreat on markings for "slow zones" suggests otherwise. But the history of the Bleecker St – Broadway-Lafayette station on the New York City subway is a stark reminder that such changes don’t happen on their own in this city. The city’s IND subway network built Broadway-Lafayette station in 1936 immediately under Bleecker St station of the Interborough Rapid Transit Corporation. In 1940, the city subsequently took over the IRT and its rival BMT subway, forming them with the IND into an allegedly unified system enjoying the benefits of being a single network. Yet it was only in June 2012, after I arrived in New York, that a full connection between the two stations – which had sat immediately adjacent to each other for 76 years – was finally opened.

If New York is serious about encouraging more than a hardy band of souls to cycle round the city, changes to its cycling infrastructure cannot possibly take that long.
