A smug expectation, a messy reality - and why it's time to get to grips with a tough conundrum

Before I got out on my bike, I was anticipating that Monday, January 9, was going to be my smuggest cycling day since returning to London from New York in July. A strike by station staff on the London Underground had brought the busiest bits of the capital’s most important public transport system to a halt. And, as I sat at home writing initial stories about what was happening, I noticed account after account of chaos on the roads as would-be underground users turned to cars and buses to get to work. I imagined myself slipping casually through the traffic on my bike, warmly congratulating myself on the excellence of my transport choices.

In the event, the day ended up feeling less like a triumph and more like a reminder of the acuteness of the transport policy challenges facing London. By the time I left home to ride to the office, around 10am, the bus lanes that I’d normally use for the early stages of my journey were choked with other forms of motor traffic. Progress was so slow I retreated to the side streets, which in places were little better.

The incident dramatised an issue that’s been worrying me for some time. London’s roads become congested when people are emptied out of the underground and other non-road forms of transport onto the roads. Yet it’s an uncomfortable truth of campaigns to encourage cycling in inner London that the vast bulk of the growth in cycle commuting must be coming from a similar, slow-motion shift from rail-based modes onto already over-stretched streets. More and more complex demands are being heaped onto constrained roadspace, without much sign of a strategic plan to manage the resulting pressures.

On top of that, I noticed once I got to work how many twitter users were complaining of having hours spent on buses even on short journeys. Later in the week, would-be commuters on Southern, the mainline rail service, would undertake similarly unpleasant journeys during strikes by their service’s drivers. The stories illustrated the shortcomings of decades of efforts to encourage cycling. Cycle provision in most of London still consists of signed routes down backstreets, most of which are growing ever busier and less attractive. It’s clear that most people will not consider riding on these, even in the most desperate circumstances.

Faced with placating demand for better cycle provision and the challenges of congested, polluted roads, Sadiq Khan, London’s mayor, seems anxious about building more of the direct, segregated cycle routes that might get such reluctant cyclists pedalling.

The challenge for everyone in London who wants more, safer cycling in central London is to devise arguments for better provision that recognise the new realities. It’s vital as the system accommodates growing cycling to safeguard road provision for the buses, delivery vehicles, emergency vehicles and other vital road-users that make up a high proportion of central London’s current road users. The challenge is similar for advocates in other big urban centres - including New York, my old home - where people shift to cycle commuting mainly from modes that don’t depend on the roads.

to cycling before the roads get even more congested?

Yet some of the most influential figures on London’s transport scene continue to insist that the conundrum is so simple it barely exists. On January 5, Andrew Gilligan, London’s former cycling commissioner, tweeted a graph from Transport for London’s latest “Travel in London” report that attributed 75 per cent of London’s congestion to “excess traffic”. The conclusion was “blindingly obvious to all but motorists,” he wrote, dismissively.

A little digging into the statistics for central London fills in the details of the policy dilemma. Traffic volumes entering Central London fell 3.4 per cent between the June to September quarter in 2015 and the same quarter in 2016, part of a long-term decline that’s seen the volume of motor traffic entering central London decline by more than 20 per cent since 2000. Instead of increasing with declining traffic volumes, however, average traffic speeds in central London - the easiest available proxy for congestion - fell 3.5 per cent, to 7.8mph. The network’s capacity is very clearly falling even faster than motor vehicle are going away. The amount of traffic that it takes for traffic to become “excess” is falling.

It is not clear, either, which part of the traffic can easily be reduced to alleviate the problem and free up space for cycling. The same Travel in London report that Andrew Gilligan quoted says that private cars now account for only 18 per cent of motor traffic during weekdays in the central London congestion charging zone. The other vehicles - private-hire cars, taxis, vans and heavy lorries - all have at least some arguable economic reason to be in the area. They are likely to be more resistant than private vehicle owners to stopping driving in the area.

crackdowns on private cars or encouragement for cargo bikes
will solve this problem.

One of the most popular suggestions among cyclists for reducing the traffic is that more of the growing numbers of internet deliveries being made in central London could be shifted to cargo bikes. The idea is sufficiently attractive that I investigated the subject in my day job for a piece about the growing numbers of cargo bikes I see around central London. Yet I emerged from interviewing even courier companies that use cargo bikes a little depressed. While cargo bikes were helping them to make urgent deliveries despite the heavy traffic, courier companies told me, they would always be a niche vehicle compared with the vans that were their fleets’ mainstays.

Amid this growing crisis, meanwhile, the one unutterable suggestion among cycle campaigners is that the building of segregated cycle superhighways along a number of central London roads might be contributing to the problem. When Florence Eshalomi, a member of the London Assembly, asked cyclists on twitter on January 11 whether they agreed with a senior TfL manager that cycle lanes had had some impact on bus journeys, the replies mostly struck a similar note.

“Making London a byword for cycling is more important than bus usage,” one twitter user replied.

“I think any far measurement of bus delays would show that excess cars are the main cause,” wrote another. “There aren't that many cycle lanes.”

The replies drew on the now-conventional wisdom among London cyclists that the 12 miles of new cycle superhighways in central London - which I love using, especially when with my children - have had no significant effect on congestion. The facilities, however, have been put in on arterial roads that were already operating at or near full capacity. They have, crucially, introduced new, cyclist-only light phases that can only have introduced extra waiting time for motor vehicles both on the streets with the new facilities and those crossing them.

While there are plenty of other factors restricting London’s road capacity, it seems fanciful to imagine that cycle facilities alone can remove capacity from busy roads and have little effect on congestion. It is certainly clear the capacity of London’s roads fell around the time the new facilities were built. It is not unreasonable, it seems to me, for Sadiq Khan and Mike Brown, commissioner of Transport for London, to seek to reduce the effect of any new facilities on congestion before giving them the go-ahead.

Yet to say that the challenges facing London’s leaders are hard is very definitely not to say they are impossible. It is quite clear, for example, that action that reined in the growth of services such as Uber in central London could have a significant effect. Private hire vehicles - the vehicles that provide the Uber service - now account for 12 per cent of traffic in central London on weekdays. Any measure that makes deliveries to the scores of construction sites in central London more efficient could free up significant amounts of road space. It is hard to understand why low-emission vehicles, which take up the same road space as others, remain entirely exempt from congestion charging.

It is regrettable, meanwhile, that London relies so heavily on the double-deck New Bus for London given its poor capacity and the time it takes to load and unload. A wholesale reform and extension of the current central London congestion charge to make it more sophisticated and more closely related to the space each vehicle takes up on the road seems overdue. The mayor should continue to pursue increases in cycling because bikes provide clean, healthy, flexible transport. Extra cycling journeys can almost certainly be catered for more economically than extra journeys on the underground.

more cycling might avert such incidents

It is far too easy, however, for the debate over this complex issue to slip into glibness. Taxi driver groups slip into this trap when they claim the simple removal of new cycle paths would restore London’s roads to flowing freely. Cycling groups fall into it when they pretend new cycle paths magically shift London commuters from wasteful cars onto space-efficient bikes.

The rest of my ride to work on January 9 was a stark reminder of the risks of ducking serious debate. I encountered drivers engaged in fierce rows over road space, a furious woman cyclist yelling at a man who had somehow wronged her and, in van after van, long lines of stressed-looking delivery drivers and workmen. An air of unhappiness and frustration hung over everything.

While the scenes were far worse than those on a normal day, I made an inward vow to renew my efforts to think more seriously in future about the less acute but still worrying levels of congestion I encounter daily.

If others do the same, it may prove easier to build wide support for the kind of excellent facility I found myself using towards the end of the trip. Wanting to take in the scene, I rode over Vauxhall Bridge then down the east-west cycle superhighway along the Embankment. As van and taxi drivers sat motionless in the neighbouring traffic jam, I was finally slipping by the traffic jams, as I’d anticipated. Looking at the grim faces of the stationary drivers, it was a pleasure I was keenly aware I shouldn’t take for granted.
