Frequent interruptions are irritating and destroy the rhythm of the bicycle trip. Over the years Copenhagen has introduced several solutions to reduce the problem. Bicycle paths are often carried across minor side streets without interruption, which results in bicycle trips with fewer interruptions and lets drivers know they must wait. Introducing green waves for bicycles on selected street helps correspondingly to reduce irritating stops. In order to create these green bicycle waves, stoplights are set so that when bicycles bike at about 20 km/h (12.4 mph) they need not stop when they bike to and from the city during rush hour. That service used to be provided for cars. Another form of comfort and safety for bicyclists in Copenhagen is the city practice of snow removal. The bicycle lanes are always cleared before driving lanes to emphasize bicycle priority and the invitation to bike — despite the season.

Bicycle Cities and City Bicycles

In recent years, many cities have introduced various types of city bicycles that can be borrowed or rented from stands or depots. The idea is to reinforce bicycle traffic by making it easier for people to use bicycles for short trips in the city, while providing a collective bicycle system so that individuals do not need to buy, store and repair their own bicycles. Amsterdam’s white bicycle bike-share system came and disappeared quickly from the street scene in the 1970s. More stable and well organized systems were established in the 1990s, in Copenhagen, for example. Today Copenhagen has 2,000 city bicycles available at 110 bicycle stations in the city center. The bicycles are free, financed by advertisements. Users pay a coin deposit, which is returned when the borrowed bicycle is returned to one of the official bicycle racks. Copenhagen’s city bikes are used primarily by tourists, who can bicycle around town easily and safely, thanks to the well developed bicycle network. Copenhageners rarely borrow city bicycles, because they prefer their own bikes. In brief, the principle underlying city bikes in Copenhagen is to enable inexperienced city bicyclists to ride around in a relatively safe bicycling environment.

City bike programs have by now been introduced in numerous European cities. In Paris, the pattern of use is different from that in Copenhagen. Under the Vélib program, city bicycles are used primarily by Parisians themselves. By renting a Vélib by the hour, week or year, they are able to ride a bike without the trouble of storing and maintaining it. The bicycle rental companies handle the bother in return for the rental fees they charge the bicyclists.

During 2008 the Vélib system in Paris was expanded to comprise 20,000 rental bikes parked in about 1,500 bicycle racks. In a very short time the Vélib bicycles have become a well-used service, primarily for short trips: 18 minutes on average. Here the idea is to enable many more or less experienced bicyclists acquainted with the locality to bicycle in a network that is neither very safe nor well developed. Although there have been a number of accidents, the program has had the valuable result that more people now bicycle in Paris — on rental bikes and personal bikes. In only one year the number of trips on personal bicycles has doubled, an increase that has doubtless been inspired and reinforced by the bicycle traffic on the new Vélib bicycles. The Vélib bicycles accounted for one-third of all bicycle trips in Paris in 2008, and bicycles in total accounted for between 2 percent and 3 percent of all traffic in Paris.

Inspired by the development in Paris, among other cities, many new city bicycle systems are underway at this time, also in cities that have essentially no bicycle infrastructure or bicycle culture. The idea seems to be that easily accessible city bikes can kick-start development of more bicycle cities on the principle that first you send people out on city bicycles and then you gradually develop comfortable, safe bicycle networks. There are good reasons to be cautious about sending inexperienced bicyclists out on two wheels in cities where bicycle traffic and networks do not have the critical mass to allow city bikes to reinforce ongoing development. Bicycle traffic and traffic safety must be taken seriously, and experiences from good bicycle cities incorporated, before experimenting with cheap bicycle campaigns. City bikes must be a link in efforts to build and reinforce bicycle culture — not the spearhead.

On the Way to a New Bicycle Culture

A number of cities, particularly in Scandinavia, Germany and Holland have witnessed a considerable development in bicycle use in recent years. The number of bicyclists and bicycle trips grows gradually as it becomes more practical and safe to bicycle. Biking simply becomes the way to get around town. Bicycle traffic changes gradually from being a small group of death-defying bicycle enthusiasts to being a wide popular movement comprising all age groups and layers of society from members of Parliament and mayors to pensioners and school children.

Bicycle traffic changes character dramatically in the process. When there are many bicycles and many children and seniors among them, the tempo is more stately and safe for all parties. Racing bicycles and Tour de France gear is replaced by more comfortable family bicycles and ordinary clothing. Cycling moves from being a sport and test of survival to being a practical way to get around town — for everyone.

This shift in culture from fast slalom bicycle trips between cars and many infringements of traffic regulations to a law-abiding stream of children, young people and seniors bicycling in a well-defined bicycle network has a big impact on society’s perception of bicycle traffic as a genuine alternative and reasonable supplement to other forms of transport. The shift in culture also brings bicycles more in line with pedestrians and city life in general, and is one more reason that bicycles have a natural place in this book about city life.

Cities are wonderfully innovative in their efforts to strengthen a broader bicycle culture and demonstrate that bicycles are an obvious choice for almost everyone. Schools offer intensive bicycle training, companies and institutions compete to have the highest percentage of bicyclists among their employees, and information campaigns, bicycle weeks and car-free days are held. Many cities now open bicycle streets on Sunday in campaigns to develop bicycle culture. Sunday is a particularly good day for two reasons: car traffic is usually limited and people usually have more time for exercise and experiences. The idea of closing city streets to car traffic, turning them into temporary bicycle streets instead, has been popular in Central and South America for years. The extensive “Ciclovia” program in Bogotà, Columbia is one of the best known and best developed initiatives of this kind. In the post-millennium years, the idea of reinforcing bicycle traffic has spread to more and more of those cities where cars have dominated planning for decades.

Ambitious strategies have been developed to establish extensive bicycle networks in the large Australian cities Melbourne and Sydney. Planners in both cities are hard at work laying out new bicycle lanes and moving existing lanes away from traffic and into safer “Copenhagen-style bicycle lanes” where bicycles move inside the rows of parked cars. New York City planners are working on a new traffic plan that will make NYC one of the world’s most sustainable metropolises.

New York City’s building density, flat terrain and wide streets provide good opportunities for converting car traffic to bicycle traffic, and a new bicycle network of 3,000 km/1,800 miles of bike lanes is planned for the city’s five boroughs: Manhattan, Bronx, Queens, Brooklyn and Staten Island. Work on the new bicycle lanes started in 2007 and already in the course of 2007 – 2008 about one-quarter of the planned bicycle lanes have been established and significant growth in bicycle traffic is evident. In New York the idea of closing streets to car traffic on Sundays, which NYC calls “summer streets,” was introduced in 2008 as a popular link to the efforts to develop a new bicycle culture.

In the future, concern about sustainability, climate change and health will most certainly mean that increasingly more cities, like New York City, will double their efforts to develop a new culture for city life and movement. Increased bicycle traffic is an obvious answer to many of the problems cities struggle with worldwide.

Bicycling in Economically Developing Countries

Bicycle traffic already plays a key role in the overall traffic picture in many cities in economically developing countries. However, bicycle traffic is typically given poor and dangerous conditions. People bicycle by necessity, and individual mobility is often a prerequisite for being able to get to work and earn a living. In many cities bicycles or bicycle rickshaws handle the lion’s share of goods and people transport. Dhaka in Bangladesh has 12 million inhabitants, and the city’s 400,000 bicycle rickshaws ensure cheap sustainable transport as well as providing a modest but vital income to upwards of one million people.

Many of the cities that actually have extensive bicycle traffic today unfortunately also have forces at work to reduce bicycle traffic in favor of more room for vehicular traffic. In Dhaka, for example, bicycle taxis are considered a problem for the ongoing development of the city. Small motorcycles have replaced bicycles in many cities in Indonesia and Vietnam. Only a few decades ago, large Chinese cities were world famous for their volume of bicyclists, today bicycle traffic has in many cities almost disappeared from the street scene due to traffic reprioritization or even direct bans on bicycles.

In this category of cities, giving bicycle traffic a higher priority needs to be a key ingredient in a policy aimed to effectively utilize street space, reduce energy consumption and pollution, and provide mobility for the great majority of people who cannot afford cars. In addition, investing in bicycle infrastructure is affordable in comparison with other types of traffic investment.

New direction and reprioritizing of city policy is underway throughout the world. Fortunately, this includes prioritizing bicycle traffic in many cities in economically developing countries such as Mexico City and Bogota, Columbia.
