“…After adjusting for the increased cycling volumes after track implementation, cycle tracks were associated with a significantly decreased CMVC rate. 26 Of note, the impact of these specific methodological considerations related to data availability and quality in the context of measuring counts and estimating rates will vary across countries, depending on the predominant mode of transport for the population. For example, data considerations differ when the majority of the population moves as pedestrians, as compared with a population that moves mainly in motor vehicles.…”

BackgroundThe global burden of MVC injuries and deaths among vulnerable road users, has led to the implementation of prevention programmes and policies at the local and national level. MVC epidemiological research is key to quantifying MVC burden, identifying risk factors and evaluating interventions. There are, however, several methodological considerations in MVC epidemiological research.MethodsThis manuscript collates and describes methodological considerations in MVC epidemiological research, using examples drawn from published studies, with a focus on the vulnerable road user population of children and adolescents.ResultsMethodological considerations in MVC epidemiological research include the availability and quality of data to measure counts and calculate event rates and challenges in evaluation related to study design, measurement and statistical analysis. Recommendations include innovative data collection (eg, naturalistic design, stepped-wedge clinical trials), combining data sources for a more comprehensive representation of collision events, and the use of machine learning/artificial intelligence for large data sets.ConclusionsMVC epidemiological research can be challenging at all levels: data capture and quality, study design, measurement and analysis. Addressing these challenges using innovative data collection and analysis methods is required.

“…In contrast with countries investing in active transport infrastructure, there has been a steady increase in pedestrian and cyclist fatalities in the USA, which focus transport infrastructure on personal vehicle use [70,84,85]. Studies investigating the impact of additional cycle tracks on cyclist-motor vehicle collisions, found increases in cyclist numbers and a decrease in collisions, including in areas surrounding the tracks [86]. Traffic volume and speed, low street connectivity, low residential density, land use mix, and features of the natural environment (e.g.…”

A high proportion of people are insufficiently physically active. The reasons for this are complex and in part relate to social determinants of health, lifestyle choices, and deleterious environmental conditions like climate change, loss of green and outdoor environments and a concomitant loss of biodiversity. Physiotherapists, and other health professionals, may have a positive impact on these global issues, through the encouragement of active transport, and advocacy to reduce barriers to its uptake and optimize exposure to health-giving outdoor spaces. In this paper, we demonstrate how physiotherapists can promote active transport as a planetary health intervention, and provide insight into the benefits and challenges of this planetary health intervention, with direct implications to physiotherapy practice.

“…We drew our ratio estimates from two prior studies 13,16 that collected data in Toronto. Teschke et al 13 found cycle tracks (defined as physically separated cycle lanes) offered significant protection (OR = 0.11, 95% CI: 0.02, 0.54).…”

“…Communicating findings is a challenge for public health intervention research. Studies evaluating the effectiveness of interventions often report ratios, including odds ratios (e.g., 6,7,13,14 [OR]) and others (e.g., rates 15 or risk ratios 16,17 ). These can be difficult to interpret for potential policy-and decision-makers.…”

Objectives: Bicycling is a form of active transportation with a number of health benefits but carries a high risk of injury compared to other transportation modes. Safety intervention evaluations often produce results in the form of ratios, which can be difficult to communicate to policy-makers. The primary objective of this study was to estimate the number of bicycling injuries on an urban corridor preventable by separated bicycling infrastructure. Methods: Stakeholders identified a key corridor with multiple segments having bicycling infrastructure but most of the corridor lacking similar infrastructure. We counted bicyclist volume along this route and used secondary data to supplement counts missing due to COVID-19. We used two reference studies including local bicycling population to estimate benefit of separated bicycling infrastructure and applied this to a city-wide estimate of baseline risk of injury per kilometre bicycled, which used a combination of secondary data sources including police, health care and travel survey data. Finally, we adjusted baseline risk to account for increased bicyclist volume during and following the COVID-19 pandemic. Results: We estimated installation of fully separated cycle tracks along one Toronto corridor would prevent approximately 152.9 injuries and 0.9 fatalities over a 10-year period. Discussion: Our results underscore the benefits of separated bicycling infrastructure. We identify several caveats for our results, including the limitations of studies used to estimate relative risk of infrastructure. Our method could be adapted for use in other cities or along other corridors. Finally, we discuss the role of preventable burden estimates as a knowledge translation tool.
