• A variety of perspectives are used to understand the impact of newly created facilities.
• The evidence suggests that bicycle facilities significantly impact levels of bicycle commuting, although the results are not totally free of uncertainty. For example, areas near new bicycle facilities showed considerably more of an increase in bicycle mode share than areas farther away. Observing increased cycling due to these physical interventions provides a starting point to which future research could add detail that would be needed to guide infrastructure investment.
