In the latest High Speed dispatch, guest author Darío Hidalgo ( @dhidalgo65.bsky.social ), one of the architects of the TransMilenio bus rapid transit system that transformed the city, offers his take on the coming of rail transit to his hometown: www.highspeed.blog/bogota-gets-...

These results point to a clear policy package for Colombia and similar LMICs: adopt and tailor a graduated driver licensing (GDL) system that emphasizes phased, supervised, and risk-restricted exposure during the earliest months and years of independent driving, with attention to motorcycles

Crash risk varies with region (place of issue of the driver's license) In Antioquia the model yields a pronounced peak in crash probability for inexperienced, middle‑aged drivers, followed by marked reductions as experience accumulate

Crash risk was higher for males, motorcyclists A motorcycles B light duty vehicles C trucks and buses

Predicted crash probability reduces with age (20–65 years), but also drastically with experience levels 0 years (novice drivers), 1 year 3 years (the surrounding shaded bands denote confidence intervals)

The results reveal a pronounced learning gradient: among younger drivers, an additional year of experience is associated with a substantial reduction in crash probability (steep safety gains early in the driving career) As drivers age, the marginal effect of additional experience diminishes

Younger and less‑experienced drivers face the highest motor crash risk in 🇨🇴 This shows the age-varying marginal effect (slope) of one additional year of driving experience on MVC probability, with a shaded 95% confidence interval
