My idea of a Cargo Bike Club took a small step forward today, but first a wee bit of history:

Back in the autumn of 2010, Ulli and I were faced with the problem of getting a large pumpkin home from the allotment (not a problem that we have had since due to the poor summers). The solution I suggested then was to get a cargo bike, but at that time such bikes were very few and far between in Scotland, not that there are that many more now. This led me to come up with the idea of a Cargo Bike Club as a means of making cargo bikes available to the wider population (and a way of kick-starting the market for cargo bikes in Scotland).

When I first floated the idea of the Cargo Bike Club, it attracted a lot of positive comments. My initial idea was to use the City Car Club model, where the users would pay an annual fee to join the club and then have self service access to the bikes for a small hourly hire rate. There are, however, a few technical issues with security and self service access, which I have yet to overcome.

One person who thought he could over come these problems was Will Vaughan who took my idea (he did contact me and ask first) and started However, he was planning on using a prototype technology from a small German startup called LOCK 8. I have seen the Kickstarter campaign raising funds to develop the locking system, but was sceptical about the level of security it would offer (the cable shown in the pictures is up to Solid Secure Gold level, as required by insurance companies). [Up date: I met Philipp Meyer-Scheling, the MD of Lock8 at EuroBike and am hoping to have another meeting with him in November] At the present time, it doesn’t appear he has managed to get the self service access up and running, but he does have a Bullitt available for hire in the Hereford area, so all credit to him.

The idea of the Cargo Bike Club has continued to gnaw away at me, and I have re-visited the idea a few times, but mostly I have gotten on with other projects like the Edinburgh Festival of Cycling. Where is all this rambling going, I hear you ask? Well, this year the Edinburgh Festival of Cycling Ltd has acquired an Urban Arrow cargo bike, and from today it is available to hire when not in use for company business.

Urban Arrow for hire

It is a small step, but it is a start, this is currently the only cargo bike available for hire in Edinburgh. Who knows, if this bike proves popular, there may yet be a Cargo Bike Club in Edinburgh. I am still working towards getting it off the ground one day.

There has just been a shout of Die Fledermaus from the kitchen, nothing to do with the opera by younger Johann Strauss, but Ulli was on the phone to her mother and spotted the first bat of 2015. It was probably Pipistrellus pipistrellus or Pipistrellus pygmaeus (based on previous identifications). It was earlier than last year, which was on the 15th April, but not as early as some years, 26th March 2012 and 30th March 2009.

It is great to have such opportunities to see wild life in the centre of a city, which one of the reasons I so enjoy living in Edinburgh.

The people behind Pedal on Parliament have just realised a new video, Katie rides to School, shows how if we were to make the roads safer everyone benefits. So please watch the video, join us on 25th April 2015 to Pedal on Parliament and share the message. We will all be better off when Katie rides to School!

Katie cycles to school. Katie loves cycling to school. Some of her friends do it too.

Katie’s mum bought a bike, too, to take Katie’s brother to nursery. Katie’s mum was surprised it was actually quicker on the bike. Now, when she doesn’t have to go to work, she has time to stop into town and meet her friends. On her way home, she pops into the shops.

Katie’s dad was told by his doctor to lose some weight, so he cycles too.

And at the weekend, they all go out together.

Katie cycles to school though she can only do it because her town built a cycle path very close to the school. Before that, she would have to ride in the road or on the pavement. It was just easier to go in the car.

Katie’s mum can only cycle into town because traffic is gone from the high street. Before, it was clogged with cars. It was just easier to go to the supermarket.

Katie’s dad only started cycling to work because they built a cycle track on the road on his office. Whatever the doctor said, he didn’t like having to deal with all the traffic before. He just wanted to get back safely to his family.

We believe making it safe for Katie and her friends to cycle to school, Katie’s mum to cycle to the shops, and Katie’s dad to cycle to work makes it better for everyone. Including people who don’t even cycle, like shopkeepers, pedestrians, and even other car drivers.

So that’s why we pedalled on parliament – If more kids like Katie are to cycle to school, we need safe space for cycling. If more people are to shop in the local town centre, we need roads where cars don’t dominate. If more people were to cycle to work, we need roads designed with cycling in mind.

This takes investment, but it is investment will pay back tenfold. If we do this then Scotland’s people will be healthier, our towns will be wealthier, our roads will quieter, our air will be cleaner, and our children will do better in school.But, more importantly, we will all be happier.

So join us, for Katie, for everyone – Pedal on Parliament.

For 6,000 years the street was a place where people met and talked, they traded and did business, above all they could walk where they liked. The street was a democratic space which belonged to no one group or form of transport. This all ended in the 20th Century with the arrival of the motorists who demanded that they had a greater “right” to use the road than anyone else. Pedestrians were forced to the sides and restricted in where they could cross, cyclists were barely tolerated and expected to keep out of the way. How did all this come about?

When the car first arrived, they were few in number and tightly controlled as it was recognised that motor vehicles were a danger to all. However, as the people who owned cars were wealthy and powerful these measures were soon being watered down. First off, the 1865 “Red Flag Act” was replaced by the Highways Act 1896 which set a limit of speed limit to 14mph (23km/h). This change is still commemorated each year by the London to Brighton Veteran Car Run. Then in turn this speed limit was replaced by the Motor Car Act 1903, which raised the limit again, this time to 20mph (32km/h), which is where the speed limit in built up areas should have stayed.

However, after a great deal of pressure from the motoring lobby, all speed limits for cars and motorbikes were removed by the Road Traffic Act 1930. It is very telling that Lord Buckmaster’s opinion at the time was that the speed limit was removed because “the existing speed limit was so universally disobeyed that its maintenance brought the law into contempt”. It is also worth noting that the AA was founded in 1905 to help motorists avoid police speed traps, and the RAC also has a long history of lobbying against speed restrictions.

At this time there were relatively few cars on the roads but the death rate was considerable. Data on road deaths in Great Britain were first collected in 1926, in that year there were 4,886 recorded deaths. The result of the removal of all speed limits for cars meant that in 1931 the death rate hit a new high of 7,343 deaths and 231,603 serious injuries. As a consequence, the new Minister of Transport, Leslie Hore-Belisha, described it as “mass murder” and reintroduced a speed limit for cars at 30 mph in built-up areas (defined in Scotland as areas where the lighting columns are spaced at 185m or less).

But is 30mph an appropriate speed for motor vehicles in a built up area? Well no, as this infographic from Pedal on Parliament [] clearly shows:

Speed & Fatalities

As speed increases so the survivability of a collision declines. Why would this be?

It’s a simple matter of physics, if streets have large amounts of kinetic (movement) energy moving along them they are more hazardous places to be. Kinetic energy can be shown by the equation Ek = 1/2mv2, where Ek is the amount of kinetic energy (usually given in Joules), m is mass or weight of the vehicle (usually given in Kg), and v2 is velocity or speed which is squared (usually given in meters per second). But what does this mean in reality? Let’s look at the kinetic energy of a small car, these weigh about one tonne (1,000Kg) travelling at 20mph (8.9m/s), so Ek = 0.5 x 1,000 x 8.92 = 39,969J (39.97kJ).

This also tells us that as speed increases, because velocity is squared, the amount of energy increases exponentially. If the vehicle speed doubles, then its kinetic energy quadruples, so at 40mph a one tonne car will now have a kinetic energy of 159.88 kJ. It also tells us that heavier cars are more lethal than lighter ones, so a big 4×4 which can weigh about three tonnes, will have a kinetic energy of 119.91kJ at 20mph and 479.63kJ at 40mph. Just to put all this into context, the kinetic/muzzle energy of a 12 bore shotgun is 4.45kJ. OK so there are some differences is the area over which the kinetic energy would be transferred, but it shows just how lethal cars can be.

Before I move on, just a quick note on the data source for the infographic above. When Donald was drawing it up, we at PoP had a discussion about which paper to take the data from and why. There are a couple of newer papers which appear to give higher survival rates at 30 mph. However, when you read the original source material, you find that the most vulnerable groups, children under 15 years and adults over 70 years, have been excluded from the analysis. No reason is given for this exclusion of data and the reader is left to draw their own conclusions, so we chose to use Aston & McKay 1979. We have received a certain amount of criticism for using “old” data, but as I have shown above, the laws of physics haven’t changed. People say that cars have changed, and yes they have, they have gotten bigger and heavier. A small car in 1979 would have weighed 500-750Kg, now 1,000 Kg, and there were very few 4×4 SUVs. The levels of kinetic energy on our roads for the same speeds are greater than they were before.

Of course the level of kinetic energy is not the only factor that makes lower speed limits safer in built up areas. There are other things to think about too, such as stopping distances, here again the same laws of physics come into play. There is the relationship between driving speed and braking distance. The kinetic energy of a vehicle is proportional to the square of its increased speed, this means that as the driving speed is doubled the braking distance quadruples. Of course there will be those who say the brakes on modern vehicles are better than they used to be. But they are not (as some drivers imagine them to be) magic, they can not overcome the laws of physics. Anti-lock brakes do not significantly reduce braking distance on a dry road, they merely reduce the risk of skidding out of control. Of course braking distance is only one component of Stopping Distance, the other part is thinking distance.

The speed with which the human brain can think hasn’t changed in well over 3 million years, no matter how much some people might want to think otherwise. (Insert your own joke here about Neanderthal taxi drivers). For an alert driver the average time between seeing a hazard and applying the brakes is 1.5 seconds. This means that at 20mph (32Km/h) the driver travels 13m while still thinking, this compares with 20m at 30mph (48Km/h) and 27m at 40mph (64Km/h). Remember this is for an alert driver, increasingly drivers are increasingly distracted by things like mobile phones and satnav systems. This can be the difference between life and death for a pedestrian or a cyclist using the same road.

As speed rises so the amount of time the driver has available to look around for hazards reduces and so does their peripheral vision.

In a busy environment there is a need for the driver to be more aware of what is going on around them. In less busy environments, i.e. motorways where the traffic is all moving in the same direction and there are fewer hazards coming from the sides, allowing the driver to focus more on what is happening in the distance. This is why motorways are generally considered to be safer than urban roads, even though motorways have higher speeds. As any trained advanced driver can tell you, driving at any speed requires constant attention and observation.

Aside from the clear safety benefits of 20mph speed limits for all road users, there are also other benefits to keeping the speed of motor vehicles below 20mph in built up areas. These include reductions in air pollution and noise pollution, both of which have an impact of human health.

There is increasing evidence that air pollution is shortening all our lives. Reducing motor vehicle speeds reduces levels of air pollution at source, so this has to be a good thing. There are some who claim that there are modelling studies suggesting that 20mph speed limits would increase pollution levels. However, there are no measurement studies I can find that bear this out. Models are only as good as the data and assumptions on which they are based, if they can’t be validated by real world data, they are worthless.

By reducing speeds by 10mph, traffic noise is reduced by about 3dB (depending on road surface). High levels of traffic noise cause stress and discourage active travel – who wants to walk along a noisy urban street? This not only bad for the health of people living in urban areas (and the majority of people do now live in urban areas), it is also bad for the local economy as it makes local shopping less attractive. “High street” businesses rely on footfall, not drive past. A study in the UK showed that people who walked to town centres spent an average of £91 per week on shopping, while motorists would spent £64 per week. Edinburgh’s bold move to bring in an almost blanket 20mph speed limit (excluding major roads), will help to make the whole city more vibrant.

The introduction of the 20mph speed limit in Edinburgh has been a long process, first we had the Southside trial. Then there was a two year consultation which showed there is significant support for 20mph speed limits. There was also cross-party support within the council with only the Tories objecting (and one of them called for more roads at 20mph in his ward, after he had voted against the city wide limit). The local chip wrapper did try to play up the “mass protest march” against 20mph, however this turned out to be 47 people organised by a taxi business. The police didn’t need to estimate the numbers which the organiser would then claim to be double. They just did a head count, as did an independent observer who said there were only 43.

Despite this evidence the politicians keep saying that reducing the national speed limit in built up areas to 20mph is unpopular with the electorate, so the question is, is 20mph so unpopular? In a recent poll commissioned by the Royal College of Paediatrics and Child Health, found that 58% of Britons “support reducing the national speed limit in built up areas to 20mph to attempt to reduce deaths from road traffic accidents”. The RCPCH recommend that we should: “Encourage physical activity for all children and young people – with and without disabilities – by creating more cycle lanes and promoting 20mph speed limits” and “Reduce the national speed limit in built up areas to 20mph to reduce the number of deaths by road traffic accidents”.

Edinburgh has now committed to doing something which Graz in Austria managed to do 23 years ago. Now if we could just get just Edinburgh to pick up a few other ideas from cities across Europe, maybe Zurich’s policy of one car out, one car in? But then that would need the City of Edinburgh Council to have the ambition to make Edinburgh a world class city.
