City-level interventions that improve street connectivity, promote safer and more cohesive urban environments, and address social inequities in infrastructure and services may help reduce motorcycle deaths and enhance road safety in the region

Built and social environment characteristics associated with motorcyclist mortality in Latin American cities from the SALURBAL study - Injury Epidemiology
Background Motorcyclists are the fastest growing road user group in Latin America, and account for 25% of all road traffic collision deaths. This study examines the relationship between motorcyclist mortality and the built and social urban environment in Latin American cities. Methods We studied 337 cities with ≥ 100,000 inhabitants in seven Latin American countries. Mortality data from 2010 to 2019 were obtained from civil registries and linked to cities defined by the SALURBAL project. Motorcyclist deaths were identified using ICD-10 codes, with redistribution of ill-defined codes. City-level measures included population, urban development, street design, public transportation, and social environment. Associations were estimated using multilevel negative binomial models. A subanalysis of 300 cities with motorcycle registration data was conducted. Results The crude city-level motorcyclist mortality rate was 4.16 per 100,000 population. Age-standardized rates varied from 0.51 to 22.60. Males had higher mortality rates, with the highest rates in 20-24-year-olds. After adjustment, cities with higher population density (RR 0.92 [95% CI 0.85–1.00]), intersection density (RR 0.91 [95% CI 0.83–0.99]), and social environment index (RR 0.88 [95% CI 0.83–0.93]) had lower motorcyclist mortality. More curvilinear street layout (RR 0.97 [95% CI 0.90,1.03]) and the presence of public transportation (RR 0.94 [95% CI 0.87,1.03]) showed a non-significant association with mortality. Higher urban development isolation (RR 1.07 [95% CI 1.00–1.14]) was associated with higher mortality, but the association weakened after adjustment. In cities with motorcycle registration data, higher rates of registered motorcycles were associated with higher motorcyclist mortality. Conclusion Motorcyclist road traffic deaths in Latin American cities are associated with specific city-level characteristics. In fully adjusted models, higher intersection density and a stronger social environment index were linked to lower mortality rates. City-level interventions that improve street connectivity, promote safer and more cohesive urban environments, and address social inequities in infrastructure and services may help reduce motorcycle deaths and enhance road safety in the region.

It's time to stop using SHARE THE ROAD signs. They're deliberately vague and often misinterpreted. The real point of the signs: to remind drivers that bike riders have a right to use the full lane and that they need to be attentive and safe around riders. They don't connote both sides bullshit.

Firstly our good traffic safety record is not an accident (pun intended). It is the result of decades of strategic work. In the 1980s Helsinki's track record was horrible. E.g. 18 pedestrians and 6 cyclists died in Helsinki's traffic in 1983. And the population was 200k lower! (~490k)

Interesting study from Germany on e-bikes and the modes they replace:
"43.1% of electric bicycle trips and 63.2% of electric bicycle mileage would have been undertaken using a car if no e-bike had been available, highlighting their substantial potential to reduce transport-related CO2 emissions"

Bonitos, feos, útiles o polémicos: la lucha por el espacio público se libra en los bancos
Estos asientos son mucho más que elementos sobre los que descansar: estructuran la experiencia del espacio público, marcan ritmos, generan encuentros y son testigos del día a día de la calle
