Crunching the numbers: how has Britain’s urban transport system changed over the last ten years?

Dramatic shifts are changing the face of transport and travel in city regions – and the new Number Crunch report from the Urban Transport Group reveals them.

There have been clear winners and losers in urban transport over the last ten years. Whatever people may say about the daily grind of rail commuting, rail’s USP of rapid access into congested urban centres has led to some staggering rates of growth – not just in London, but in the regions too.

For example, the latest figures show that more people now commute into central Birmingham by rail than car. But some stunning growth has occurred in other places too – with rail patronage soaring in a decade in places like Huddersfield (by 91 per cent), Coventry (by 143 per cent) and Newton-le- Willows (by 120 per cent).

If rail had a great decade, then the bus had another terrible one, haemorrhaging users like the body count in a Tarantino movie: one in 10 bus users have gone elsewhere in the Metropolitan areas just since 2009-10. Even Londoners started to drift away, despite the city having one of the best bus services in the world – although, to be fair, that patronage decline is after many years of rapid growth.

It would take a separate article to go into all the potential reasons why buses are not feeling the love from the public – but one of them could be related to the big winner on the roads over the last decade. That’s the taxi or, to be more precise, the Private Hire Vehicle (PHV). PHVs are up 41 per cent across the country in the last decade, with a doubling in London, which amazingly, now has one PHV for every 100 people.

So that’s the last 10 years in a nutshell. But what has changed more recently? The picture is less clear: goodbye big trends, hello uncertainty.


The most recent statistics show a softening of demand on rail in general and for public transport across the piece in some places – including London. This could be a blip; it could be the economy; it could prove to be differential (with a following policy wind there must be more potential for rail to eat into the car’s high current market share in many parts of the country).

There is also evidence to suggest that the impacts of transformative technological and social change are beginning to kick in – and at scale. The runaway growth in PHV numbers is a symptom of the first wave of change to crash over cities – that is, Uber and their ilk. Dockless bikes was the second. Who knows what will result from the next time a bottomless pit of venture capital and new tech make beautiful music together to create a focussed and ‘sticky’ consumer offer?

And although rail has enjoyed a decade of success, perhaps that too is changing because more people would rather not grumpily cram on an expensive train when they can work from the comfort of their own home or better still, work less. This could be a factor in why National Rail season ticket sales are slumping or why on some urban transit systems they are holding up – but people are making less trips with them.

These patterns are also backed up by the wonderful institution that is the National Travel Survey (the ‘shipping forecast’ of transport planning). The latest survey shows that people have been making less trips every year since the seventies with trips for commuting, leisure and shopping currently going down fast.

There are further trends going on out there, beyond just transport, but that have the potential to dramatically affect it. The number of over 75s in the city regions is expected to grow by 80 per cent by 2039 – from 1.3m to 2.4m people. And whilst everyone is all over the research that shows young people are increasingly immune to the lure of the driving licence, less well known is that the growth in drivers licences among older people (particularly women) is more than cancelling out the impact of the increasing numbers of millennial motoring refuseniks.

The growth in numbers of older people of course has implications for concessionary travel and the accessibility of public transport. But it would be a big mistake to assume all older people are as portrayed by their symbol on the UK’s roads signs. Many are more active than those still stuck behind a desk, and are as equally unenthusiastic about bus travel: the use of the free older concessionary bus pass is going down.

The Urban Transport Group brings together the public sector transport authorities for the UK’s largest urban areas. We are working with our members – the UK’s largest public sector city region transport authorities – to drill down into all the factors that are behind long-term and more recent patronage change.

The IPPC report on the melting ice caps makes for terrifying reading

Earlier this year, the Intergovernmental Panel on Climate Change (IPCC) – the UN body responsible for communicating the science of climate breakdown – released its long-awaited Special Report on the Ocean and Cryosphere in a Changing Climate.

Based on almost 7,000 peer-reviewed research articles, the report is a cutting-edge crash course in how human-caused climate breakdown is changing our ice and oceans and what it means for humanity and the living planet. In a nutshell, the news isn’t good.

Cryosphere in decline

Most of us rarely come into contact with the cryosphere, but it is a critical part of our climate system. The term refers to the frozen parts of our planet – the great ice sheets of Greenland and Antarctica, the icebergs that break off and drift in the oceans, the glaciers on our high mountain ranges, our winter snow, the ice on lakes and the polar oceans, and the frozen ground in much of the Arctic landscape called permafrost.

The cryosphere is shrinking. Snow cover is reducing, glaciers and ice sheets are melting and permafrost is thawing. We’ve known this for most of my 25-year career, but the report highlights that melting is accelerating, with potentially disastrous consequences for humanity and marine and high mountain ecosystems.

At the moment, we’re on track to lose more than half of all the permafrost by the end of the century. Thousands of roads and buildings sit on this frozen soil – and their foundations are slowly transitioning to mud. Permafrost also stores almost twice the amount of carbon as is present in the atmosphere. While increased plant growth may be able to offset some of the release of carbon from newly thawed soils, much will be released to the atmosphere, significantly accelerating the pace of global heating.

Sea ice is declining rapidly, and an ice-free Arctic ocean will become a regular summer occurrence as things stand. Indigenous peoples who live in the Arctic are already having to change how they hunt and travel, and some coastal communities are already planning for relocation. Populations of seals, walruses, polar bears, whales and other mammals and sea birds who depend on the ice may crash if sea ice is regularly absent. And as water in its bright-white solid form is much more effective at reflecting heat from the sun, its rapid loss is also accelerating global heating.

Glaciers are also melting. If emissions continue on their current trajectory, smaller glaciers will shrink by more than 80 per cent by the end of the century. This retreat will place increasing strain on the hundreds of millions of people globally who rely on glaciers for water, agriculture, and power. Dangerous landslides, avalanches, rockfalls and floods will become increasingly normal in mountain areas.


Rising oceans, rising problems

All this melting ice means that sea levels are rising. While seas rose globally by around 15cm during the 20th century, they’re now rising more than twice as fast –- and this rate is accelerating.

Thanks to research from myself and others, we now better understand how Antarctica and Greenland’s ice sheets interact with the oceans. As a result, the latest report has upgraded its long-term estimates for how much sea level is expected to rise. Uncertainties still remain, but we’re headed for a rise of between 60 and 110cm by 2100.

Of course, sea level isn’t static. Intense rainfall and cyclones – themselves exacerbated by climate breakdown – can cause water to surge metres above the normal level. The IPCC’s report is very clear: these extreme storm surges we used to expect once per century will now be expected every year by mid-century. In addition to rapidly curbing emissions, we must invest millions to protect at-risk coastal and low-lying areas from flooding and loss of life.

Ocean ecosystems

Up to now, the ocean has taken up more than 90 per cent of the excess heat in the global climate system. Warming to date has already reduced the mixing between water layers and, as a consequence, has reduced the supply of oxygen and nutrients for marine life. By 2100 the ocean will take up five to seven times more heat than it has done in the past 50 years if we don’t change our emissions trajectory. Marine heatwaves are also projected to be more intense, last longer and occur 50 times more often. To top it off, the ocean is becoming more acidic as it continues to absorb a proportion of the carbon dioxide we emit.

Collectively, these pressures place marine life across the globe under unprecedented threat. Some species may move to new waters, but others less able to adapt will decline or even die out. This could cause major problems for communities that depend on local seafood. As it stands, coral reefs – beautiful ecosystems that support thousands of species – will be nearly totally wiped out by the end of the century.

Between the lines

While the document makes some striking statements, it is actually relatively conservative with its conclusions – perhaps because it had to be approved by the 195 nations that ratify the IPCC’s reports. Right now, I would expect that sea level rise and ice melt will occur faster than the report predicts. Ten years ago, I might have said the opposite. But the latest science is painting an increasingly grave picture for the future of our oceans and cryosphere – particularly if we carry on with “business as usual”.

The difference between 1.5°C and 2°C of heating is especially important for the icy poles, which warm much faster than the global average. At 1.5°C of warming, the probability of an ice-free September in the Arctic ocean is one in 100. But at 2°C, we’d expect to see this happening about one-third of the time. Rising sea levels, ocean warming and acidification, melting glaciers, and permafrost also will also happen faster – and with it, the risks to humanity and the living planet increase. It’s up to us and the leaders we choose to stem the rising tide of climate and ecological breakdown.
