Cities with higher population density, intersection density and social environment index had lower motorcyclist mortality. More curvilinear street layout and the presence of public transportation showed a non-significant association with mortality

Cities with higher population density, intersection density and social environment index had lower motorcyclist mortality. More curvilinear street layout and the presence of public transportation showed a non-significant association with mortality
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.
Yannone et al. (2025)
Colombia 8.6 motorcycle deaths per 100,000 people (2.63 F, 14.89 M)

Some applications, like Bogotá BRT, have been able to carry extreme ridership at a very low relative cost
Calling it a failed planning concept is not precise
