Once you recognize that widening roads always leads to more congestion, the case for (de)congestion pricing + transit investment is obvious.

1 year after the introduction of a generalized 30 km/h limit in Bologna, the results are quite encouraging.
For the first time since systematic data has been collected (1991), there has been zero (zero!) pedestrian killed in a road accident in 2024.

Todo un tema xa pensar la presuncion de responsabilidad en seguridad vial. En muchos casos ya se usa (el q choca desde atrás se presume responsable, o el q estaba cometiendo una infracción por ejemplo). Algunos paises lo usan para proteger peatones/ciclistas (se presume responsable al mas peligroso)

En discusiones sobre movilidad termina apareciendo la frase 'el objetivo de la calle' (o de la red vial). Pero no es una buena forma de plantear la discusion:
No tiene por que haber UN solo objetivo. Hay muchos y en algunos aspectos no son del todo compatibles entre si. Mucho menos son optimizables

Hoy planteaba en 'la red mala' q para mi es discutible q una ciudad (en este caso CABA) priorice los viajes de largo recorrido sobre los de cercanía. Hay mucho mito sobre la necesidad de priorizar viajes largos cuando la gran mayoria de los viajes son relativamente cortos. La activida no esta ahi

Car bloat describes two shifts:
- The replacement of sedans and station wagons by SUVs and pickups
- The expansion of individual models
In the US, it’s been a defining trend of the auto market over the last 40 years.

New study from IIHS shows that car bloat is dangerous even at low speeds:
If hit by a sedan going 27 mph, a pedestrian has a 60% chance of a moderate+ injury and 30% chance of a serious one.
If it's a pickup going 27 mph, those odds rise to 83% and 63%, respectively.

Vehicle height compounds dangers of speed for pedestrians
New pedestrian injury risk curves calculated by IIHS show that vehicles with taller front ends begin to cause serious injuries at lower speeds.
