In pictures: Do cars take up too much space on city streets?

A while ago, we ran some images of cyclists in Latvia protesting in favour of more bike lanes. They'd strapped neon pieces of wood to their bike frames so as they cycled on Riga's rush-hour roads, they took up the same amount of space as cars:

 

The protest made an important point: that, of all the arguments in favour of cutting the number of cars on our roads, perhaps the most compelling is one that doesn't rely on a belief in climate change, or even statistics on car-releated deaths. It's their sheer size. 

The fact is, in cities where space is limited, giant, motorized boxes carrying an average of two or three people are a massively inefficient form of transport. Handing over a huge proportion of our public space (it's around 80 per cent in London) to roads populated overridingly by cars might not be the best idea either. 

The Latvian protest was far from the first to make this argument. Here are some of the other visualisations we think make the point best.

How much space do cars actually take up?

The Copenhagenize cycling blog recently analysed transport modes at intersections in Paris, Calgary and Tokyo. The resulting diagrams, which compare the number of transporation devices with the space given over to them, look a little like this:

The clusters of dots in small areas shows how space for cars seems to be prioritised. Or, as the blog's creator, Mikael Colville-Anderson, would have it, the "blatant injustice of space allocation". 

What if roads were giant holes in the ground?

Ok, this one's a bit dramatic. But for busy streets, or in cities where jaywalking's illegal, it's not such a ridiculous representation. At the very least, the picture highlights just how much space is taken up by roads, compared to crosswalks and sidewalks. 

How much space do 69 people take up?

This next image was created by the Cycling Promotion Fund earlier this year. It shows how much road space a group of people take up using cars, a bus, bikes, or standing in a group:

Turns out it's not such a new concept, though. This bus promotion poster circulated in London in the 1960s:

Passive aggressive bike parking spaces

These bike parking areas, like our friends the Latvian cyclists, make a pointed comment on how space usually occupied by cars can be used. A single parking space, it turns out, could store 10 to 15 bikes.

For more on parking, see this video on how Zurich froze the number of downtown parking spaces in 1996 and, amazingly, the city continued to function. In this case, demand fell with parking supply: once cars weren't so convenient, residents turned to walking, cycling and public transport. 

 
 
 
 

When should you forget the bus and just walk?

Might as well talk, tbh. Image: Getty.

It can often be tempting to jump on a bus for a short journey through the city, especially when it’s raining or you’re running behind schedule. Where there are dedicated bus lanes in place, it can feel as though you speed past gridlocked traffic. But as city authorities begin new initiatives to get people walking or cycling, that could all change – and so could you.

British people are wasting tens of hours in traffic every year: London comes top, with the average commuter spending 74 hours in traffic, followed by Manchester, with 39 hours and Birmingham and Lincoln, both with 36 hours.

It might surprise some people to learn that cities are intentionally slowing down private vehicles, in order to shift people to other, more efficient, modes of transport. In fact, Transport for London removed 30 per cent of the road capacity for private vehicles in central London between 1996 and 2010. That trend continues today, as the organisation gives over more space for buses, cyclists and pedestrians.

Clamp down on cars

The loss of road capacity for cars has occurred across most UK cities, but not on the same scale everywhere. The good news is that the changes, when made, appear to have reduced actual car congestion. It seems that by making it less attractive to use your car, you’ll be more likely to use other transport. In fact, the average speed of buses and cyclists can be up to twice as fast as normal traffic in cities such as London.

The relationship between walking and improved health has been proven to such an extent that it seems everyone – your doctor, your family, regional and national government – wants to increase physical activity. The savings in health care costs, are via improved fitness, reduced pollution and improved mental health, and its impact on social care are huge.

For instance, Greater Manchester wants to increase the number of people who get the recommended level of exercise (only about half currently do). The most advanced of these plans is London’s, which has the specific goal of increasing the number of walks people take by a million per day.

So, the reality is that over the next few years, walking will gradually appear more and more “normal” as we are purposefully nudged towards abandoning our rather unhealthy, sedentary lifestyles.


The long journey

Consider this: the typical bus journey in the UK is almost three miles, with an average journey time of around 23 minutes. The equivalent walk would take approximately 52 minutes, travelling at just over three miles per hour. It seems obvious that the bus is much faster – but there’s much more to consider.

People normally walk at least a quarter of a mile to and from the bus stop – that’s roughly ten minutes. Then, they have to wait for a bus (let’s say five minutes), account for the risk of delay (another five minutes) and recover from the other unpleasant aspects of bus travel, such as overcrowding.

This means that our 23 minute bus journey actually takes 43 minutes of our time; not that much less than the 52 minutes it would have taken to walk. When you think of the journey in this holistic way, it means you should probably walk if the journey is less than 2.2 miles. You might even choose to walk further, depending on how much value you place on your health, well-being and longevity – and of course how much you dislike the more unpleasant aspects of bus travel.

The real toss up between walking and getting the bus is not really about how long it takes. It’s about how we change the behaviour and perceptions we have been conditioned to hold throughout our lives; how we, as individuals, engage with the real impacts that our travel decisions have on our longevity and health. As recent converts to walking, we recommend that you give it a go for a month, and see how it changes your outlook.
