“…We found a similar pattern with the negative associations of increased employment density ( Chen and Shen, 2016 ), and suitable pavement conditions ( Reynolds et al, 2009 ) with fatal collisions. Importantly, we also found a pattern that indicates that the presence of bicycle pathways is negatively associated with fatal collisions, which is consistent with what has been reported for high income-countries ( Marqués and Hernández-Herrador, 2017 ). Contrary to what we hypothesized, the LTS was negatively associated with fatal collisions.…”

“…Bicycling safety is an active research field recently enriched with multiple perspectives provided by different data analysis techniques ( DiGioia et al, 2017 ; Reynolds et al, 2009 ; Vecino-Ortiz et al, 2018 ). Studies assessing bicycling safety differences over time have used multiple methods, including the evolution of risk approaches in Seville (Spain) ( Marqués and Hernández-Herrador, 2017 ), longitudinal deaths analysis in the United States ( Cummings et al, 2006 ), rates per capita comparisons in Organization for Economic Co-operation and Development (OECD) member countries ( Buehler and Pucher, 2017 ), and assessments of the impact of policy on risk and exposure ( Mooney et al, 2018 ). The findings in these studies indicate improvements in safety conditions when controlling for exposure variables and standardizing bicycle collision counts per bicycle trips or capita.…”

“…Econometric models are widely used to study associations to derive policy recommendations ( Chen et al, 2017 ; Lin et al, 2017 ; Prabhakar and Rixey, 2017 ). Other methodologies include Impact Evaluation assessment ( Jensen, 2007 ; Marqués and Hernández-Herrador, 2017 ), Latent Class Clustering ( Kaplan and Prato, 2013 ), among many others ( DiGioia et al, 2017 ; Reynolds et al, 2009 ).…”

“…These contextual variables include intersections (see Chen and Shen, 2016 and Moore et al, 2011 ), speed limits (see Kaplan and Prato, 2013 and Lawrence et al, 2015 ), and signaling ( Chen et al, 2017 ; Johnson et al, 2010 ). Nonetheless, the most relevant variables with mixed results are dedicated bicycle infrastructure (see Jensen, 2007 and Marqués and Hernández-Herrador, 2017 ), and Level of Traffic Stress (LTS) measurements ( Mekuria et al, 2012 ), since these are both critical policy planning and intervention tools ( Dill and Carr, 2003 ; Macmillan et al, 2014 ).…”

Highlights Standardized bicycling collision rates have decreased in Bogotá in the last 7 years. Seven main geographic areas of bicycling risk were identified in Bogotá. Risk factors associated with bicycling mortality differ by sex. Findings support policy-making to implement targeted interventions to improve safety. Methodology based on open-data sources to permit replication and monitoring.

“…Launching the entire grid at once might have helped protect the bike lanes if Edmonton had a change in political power in the election that occurred in the first riding season. Previous research has shown that there are significant safety advantages for connected networks of bike infrastructure (Marque´s and Herna´ndez-Herrador, 2017). In addition, we observed that simultaneous broad-scale deployment of bicycling networks may provide the additional advantage of avoiding repeated social media controversy for each new phase of construction.…”

From advocacy to acceptance: Social media discussions of protected bike lane installations

Many North American cities are building bicycling infrastructure. Lively discussions on social media, where people passionately support or reject bicycling infrastructure projects, provide a unique data set on attitudes towards bicycling infrastructure. Our goal is to analyse social media posts in Edmonton and Victoria, Canada as new bike infrastructure was implemented to understand the thematic and social elements of the conversation and how these changed over time. We collected Twitter messages ( n = 13,121: 7640 in Edmonton; 5481 in Victoria) and compared three timeframes: before lanes opened (January 2015 to lane opening); the first riding season (opening to April 2017); and the second riding season (May 2017 to November 2018). For each timeframe, we evaluated word-combination frequencies (to understand the use of language) and social network structures (to understand which accounts were influential and how they interacted). We observed a change in the three time periods. Before the bicycling infrastructure was built, Twitter activity was focused on advocacy, which was especially strong in Victoria. The first riding season had the most social media activity, the most diverse perspectives and the most controversy. The second riding season held more support. Based on the Twitter activity, we found that Edmonton had more support from local businesses and traditional media, launching a connected network of infrastructure with less social media opposition. Our results suggest that attitudes associated with change in bicycling infrastructure may have a cycle, with initial negative responses to change, followed by an uptick in positive attitudes.

Public Health Autonomy: A Critical Reappraisal

The ethical principle of autonomy is among the most fundamental in ethics, and it is particularly salient for those in public health, who must constantly balance the desire to improve health outcomes by changing behavior with respect for individual freedom. Although there are some areas in which there is a genuine tension between public health and autonomy—childhood vaccine mandates, for example—there are many more areas where not only is there no tension, but public health and autonomy come down to the same thing. These areas of overlap are often rendered invisible by a thin understanding of autonomy. Better integrating newer theoretical insights about autonomy into applied ethics can make discussions of public health ethics more rigorous, incisive, and effective. Even more importantly, bringing modern concepts of autonomy into public health ethics can showcase the many areas in which public health and autonomy have the same goals, face the same threats, and can be mutually advanced by the same kinds of solutions. This article provides a schema for relational autonomy in a public health context and gives concrete examples of how autonomy can be served through public‐health interventions. It marshals insights from sociology, psychology, and philosophy to advance a theory of autonomy and coercion that recognizes three potential threats to autonomy: threats to choice sets, threats to knowledge, and threats to preferences.
