A simple modification to our cities can save a lot of lives: add more and better bicycling infrastructure. Researchers looked into quantifying how many lives we can save by replacing car journeys with bicycle use and the results aren’t surprising, but will hopefully influence people. The harms vehicular traffic does to our bodies and our communities are well documented so the fact that using car less will save lives isn’t schocking. It’s great to see more evidence and analysis into how getting rid of cars will improve everyone’s well being.
Biking plays a significant role in urban mobility and has been suggested as a tool to promote public health. A recent study has proposed 2050 global biking scenarios based on large shifts from motorized vehicles to bikes. No previous studies have estimated the health impacts of global cycling scenarios, either future car-bike shift substitutions.
We found that, among the urban populations (20–64 y old) of 17 countries, 205,424 annual premature deaths could be prevented if high bike-use scenarios are achieved by 2050 (assuming that 100% of bike trips replace car trips). If only 8% of bike trips replace car trips in a more conservative scenario, 18,589 annual premature deaths could be prevented by 2050 in the same population. In all the countries and scenarios, the mortality benefits related to bike use (rather than car use) outweighed the mortality risks.
