Bikeability
Bikeability describes the ease and safety of riding a bicycle for all trip purposes in an area, neighborhood, city, region, or country. Cycling for daily trips can help increase the sustainability of the transport system. Actual and perceived safety from motorized traffic is crucial for bikeability. It is important to provide integrated networks of bikeways, traffic calmed streets, and safe intersections, which facilitate bikeability for all grou…
Redrawing the Planners’ Circle
Problem, research strategy, and findings For decades, planners have been drawing circles of a quarter-mile radius to determine easily walkable distances for neighborhood and activity center planning. However, the radius of such “planners’ circles,” or walksheds, is often informed more by convention than by data. Here we examine walk-trip distances based on two national household travel surveys for the United States and Germany. We describe how wa…
Promoting Bicycling in Car-Oriented Cities
This paper compares bicycling in Washington, DC and Frankfurt am Main, Germany, two car-oriented cities that had adapted their urban transport system to car travel during the 20th century. Our comparative case study shows that both cities have been successful in increasing the percentage of trips made by bicycle between the late 1990s and 2018: Washington, DC from 1% to 5% and Frankfurt from 6% to 20% of trips. Both cities had detailed bike plans…

Are cars used differently in Germany than in California? Findings from annual car-use profiles
Copenhagenize
Cycling towards a more sustainable transport future
As argued in our 2008 article “Making Cycling Irresistible”, cycling is probably the most sustainable urban transport mode, feasible not only for short trips but also for medium-distance trips too ...
Reducing car dependence in the heart of Europe
Munich, Berlin, Hamburg, Vienna, and Zurich – the largest cities in Germany, Austria, and Switzerland – have significantly reduced the car share of trips over the past 25 years in spite of high motorisation rates. The key to their success has been a coordinated package of mutually reinforcing transport and land-use policies that have made car use slower, less convenient, and more costly, while increasing the safety, convenience, and feasibility o…
Trends in Walking and Cycling Safety
Objectives. To examine changes in pedestrian and cyclist fatalities per capita (1990–2014) and per kilometer (2000–2010) in selected high-income countries, and in fatalities and serious injuries per kilometer by age in the United States and Germany (2001–2009). Methods. We used Organisation for Economic Cooperation and Development data to estimate 5-year annual averages of per-capita fatalities relative to the 1990–1994 average. To control for ex…
Bikeway Networks
Research linking bikeway infrastructure and cycling levels has increased significantly over the last 20 years — with the strongest growth since 2010. The research has evolved from the study of lanes and paths, to include analyses of the role of intersection treatments, and finally to studies that attempt to measure the whole bike network. Most studies suggest a positive relationship between bikeway networks or aspects of the network and cycling l…
Safer Cycling Through Improved Infrastructure
In this article, the author examines efforts to improve cycling safety in the U.S. Particular focus is given to cycling safety in countries including the Netherlands, Germany and Denmark. Additional topics discussed include implementing policies and improving infrastructure and technology, cycling in Boston, Massachusetts, and the importance of bike lanes
The multimodal majority? Driving, walking, cycling, and public transportation use among American adults
Men Shape a Downward Trend in Car Use among Young Adults—Evidence from Six Industrialized Countries
This paper investigates trends in the travel behaviour of young adults in Germany, France, Great Britain, Japan, Norway, and the USA over the past few decades with a focus on car availability and car travel. The trend analysis relies on micro-data from over 20 National Travel Surveys from the study countries dating back to the mid-1970s. The analysis of the survey data is supplemented by official statistics on licence holding. On this basis, this…

Bicycling renaissance in North America? An update and re-appraisal of cycling trends and policies
Walking and Cycling in the United States, 2001–2009
Objectives. To assess changes in walking and cycling in the United States between 2001 and 2009. Methods. The 2001 and 2009 National Household Travel Surveys were used to compute the frequency, duration, and distance of walking and cycling per capita. The population-weighted person and trip files were merged to calculate the prevalence of any walking and cycling and of walking and cycling at least 30 minutes per day. Results. The average American…
Determinants of transport mode choice
Transport Policies, Automobile Use, and Sustainable Transport
The automobile contributes to costly trends like pollution, oil dependence, congestion, and obesity. This article investigates determinants of individual car travel through a comparison of Germany and the USA. Even controlling for socioeconomic variables and spatial development patterns, two comparable national travel surveys show that Germans are less car-dependent than Americans. Multivariate analysis reveals that car travel demand in the USA i…
Walking and Cycling to Health
Objectives. We sought to determine the magnitude, direction, and statistical significance of the relationship between active travel and rates of physical activity, obesity, and diabetes. Methods. We examined aggregate cross-sectional health and travel data for 14 countries, all 50 US states, and 47 of the 50 largest US cities through graphical, correlation, and bivariate regression analysis on the country, state, and city levels. Results. At all …
Walking, Cycling, and Obesity Rates in Europe, North America, and Australia
Purpose: This study was designed to examine the relationship between active transportation (defined as the percentage of trips taken by walking, bicycling, and public transit) and obesity rates (BMI ≥ 30 kg · m −2 ) in different countries. Methods: National surveys of travel behavior and health indicators in Europe, North America, and Australia were used in this study; the surveys were conducted in 1994 to 2006. In some cases raw data were obtain…
Making Cycling Irresistible
This article shows how the Netherlands, Denmark and Germany have made bicycling a safe, convenient and practical way to get around their cities. The analysis relies on national aggregate data as well as case studies of large and small cities in each country. The key to achieving high levels of cycling appears to be the provision of separate cycling facilities along heavily travelled roads and at intersections, combined with traffic calming of mos…
