The Good, the Bad and the Ugly Cyclists’ protests can be a good thing arising out of a bad thing. Confused? by Pedro Madruga The Good The number of actions protesting for more cyclist and pedestrian rights is becoming more common, large-scaled and with increased outcomes.  Most of us are aware of the protests in Denmark and Netherlands during the 70’s, aiming mostly for increased safety. If you're not aware of that then here’s a whole article waiting for you here . Back then, a message was sent to politicians: the ink was made of cyclists and pedestrians and the paper was the city hall square – as you can see in the below picture (Copenhagen). It figuratively said: “enough”. And it worked. Without violence, just pure human kinetics. Throughout history there were several protests were cyclists and pedestrians claimed for better rights. Just last year, a massive protest gathered 10 thousand cyclists in the UK and 50 thousand in Italy .  And the list goes on, whet...

« We are nourishing a monster of great potential destructiveness.» Colin Buchanan, 1960. Quote referring to the car-oriented planning in a report for the Minister for Transport, UK. It was a privilege to read, over the last few days, a thesis written by Joe Goddard - a friend of Mikael's. The thesis’ full title is “Cycle Paths and City Traffic 1945-1995” and it was a work submitted to the University of Bristol, in order to obtain the Master of Arts degree in the Faculty of Historical Studies. Amazingly, it was written back in 1995. Back then there were hardly any papers about bicycle infrastructure or bicycles at all so Mr Goddard was quite ahead of the modern curve. Dr Joe Goddard is now Associate Professor of American Studies at the University of Copenhagen. His most recent book is also fascinating: Being American on the Edge - Penurbia and the Metropolitan Mi...

Motorway 16, north of Copenhagen. Cycle tracks on either side. The discussion continues unabated, around the world, about whether the bicycle can perform as a transport mode at distances above 5 km and thus present itself as alternative for motorized vehicles. First, let's consider this quote: ”In the late 19th century, large numbers of women were already using bicycles to get to work, women office workers and shop assistants wending their way each weekday morning from the suburbs to the town. They found the bicycle a convenient form of transport for distances up to, say, ten miles”. Plucked from John Woodeforde's book ”The Story of the Bicycle”, 1970 So the bicycle as an effective performer at longer distances is nothing new. Nevertheless, we're relearning the bicycle story. A published peer-reviewed conference paper (full version here - on google docs ), based on my Masters’ degree thesis in Environmental Engineering (specializing in Urban Planning), incl...

Robert Doisneau - running pedestrians in Paris We recently covered the disturbing and archaeic 85th percentile method and how it is applied for (and by) vehicles. If you thought THAT was fun, you might also enjoy The 15th Percentile. It is frequently used to determine the time between the WALK and DON'T WALK crossing signals -  in other words, how much time the engineers computer models allow for human beings to cross streets. It's not as rooted as a standard as The 85th Percentile, but it is still widespread. In a nutshell, we should be paying more attention to pedestrian crossings, when you consider statistics that say that " 40% of accidents involving pedestrians occur at these intersections ". In Europe, one in four pedestrians die on a crossing . What seems to be the problem? In the U.S., the Manual on Uniform Traffic Control Devices (MUTCD) establishes a “normal” pedestrian speed at 1.2 metres per second (m/s), so traffic signal times are set according...

Copenhagen's Lord Mayor, Frank "Le Corbusier" Jensen continues his fight for a car-centric Copenhagen that would make the 1950s proud. What makes matters worse is that the Robert Moses Fan Club that is the Danish Congestion Commission (Trængselskommission) are also using a time machine to travel back to the congested past at the moment. A colleague told us very recently that they are seriously discussing widening the motorways leading into Copenhagen because of the traffic jams. Can you believe that? With all the available knowledge, with all the moves away from motorways around the world, these clowns are tying us to their back bumpers and dragging us into that previous century that exists in their heads. The subject of 30 km/h zones was brought up at the Congestion Commissions discussions. According to Jens Loft Rasmussen, head of the Danish Cycling Federation (DCF) , the room went kind of quiet. Nobody knew quite what to say. In a flash, the proposal was wip...

It's not like we needed any more proof that we live in car-centric cities. When you start scratching just a little below the surface, however, you start to discover that we are not so much citizens in cities but rather a flock of reluctant characters in The Matrix. You discover that we live in cities that are controlled by bizarre and often outdated mathematical theories, models and engineering “solutions” that continue to be used despite the fact that they are of little use to modern cities. One of them is called The 85th Percentile. It's a method that cities all over the planet use to determine speed limits. It's the standard. Nobody questions it. Certainly not the engineers and planners who, for decades, have been served it up and who have swallowed it whole during their studies. Which reminds us of the old traffic engineer joke: Why did the engineer cross the road? Because that's what they did last year. The concept is rather simple: the speed limit of ...
