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...

The City of Copenhagen is currently planning to expand the existing, extensive network of bike lanes to extend farther out into the suburbs. A network of 13 high-class routes - 'bicycle superhighways' if you will - dedicated to bicycle commuters and aimed at encouraging more to cycle to work. Currently 37% ride to work or school in Copenhagen. While in many other countries anybody who cycles to work is often considered a 'bicycle commuter', most of the 500,000 people who cycle to work or education in Copenhagen don't fit into the Danish version of this statistical category. A 'commuter' is loosely categorised as someone who travels more than 10 km to work. The City of Copenhagen and the surrounding towns are aiming to increase the trips by bike on the new routes. There is an efficient network of public transport throughout the region but just as any train passenger or motorist knows, it feels much quicker and is much quicker if you don't have to st...

A Dutch study has proved, yet again, that the level of dangerous microparticles are higher inside cars than on bikes. I posted about how Traffic Kills More People Than Traffic Accidents before, but this recent survey reconfirms the science. Despite the air pollution it is healthier to cycle in traffic than sitting in a car. The levels of particles in the air are greater inside a vehicle than on the bike lanes. So even though a cyclist breathes in more air than a motorist, the concentration of microparticles is lower for the cyclist. The health benefits of cycling greatly overshadow the harm caused by breathing polluted air, the study adds. The study was carried out by Gerad Hoek from Utrecht University and presented in the magazine for the Dutch cyclist organisation, Fietzersbond. If a cyclist wishes to avoid unhealthy particles, it is recommended that he or she avoids areas with heavy traffic and rush hour periods. In particular, avoiding trucks and scooters exhaust is of...
