- La Agencia Nacional de Seguridad Vial debe potenciarse, no debemos diluirla fusionandola con otros 20 organismos con objetivos y valores totalmente diferentes
- Reposted by Juan del ValleOnce you recognize that widening roads always leads to more congestion, the case for (de)congestion pricing + transit investment is obvious. But if you need a study, here's a study: ssti.us/2025/02/03/c...
- Un artículo para reflexionar para qué sirve el transporte público, por qué está como está (no solo en USA) y cómo mejorarlo
- Quizás pensar un poco más como empresa puede ayudar (aunque no es ese el supuesto objetivo de las privatizaciones/concesiones?) pero no hay que olvidarse que hay un montón de decisiones del estado (infraestructura, planificación urbana, subsidios, impuestos, etc) q impactan
- Reposted by Juan del ValleThe dominant state-owned enterprise in transport, at least in the US, is road-building to encourage faster car traffic. This (a) competes with transit, (b) endangers pedestrians (all riders are pedestrians) and (c) promotes transit-inefficient development. 4/ …
- Reposted by Juan del Valle1 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. www.comune.bologna.it/notizie/citt...
- A veces resulta increible como describen los siniestros fatales algunos periodistas Veamos ejemplos: Murió alguien atropellado (desde atrás) pero periodista se preocupa porque se (le?!) rompió un paragolpes y una bici www.diario3.com.ar/?p=192483

- 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)
- Como todo en este mundo real podría ser abusado, pero de alguna manera hay q tener en cuenta q hoy da un poco la impresión de que cualquiera puede salirse con la suya atropellando a alguien...
- 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

- Reposted by Juan del ValleIs road rage getting worse? This short piece by GCN looks at why all types of road users get angry and the impact groups like #KidicalMass are having changing that. @saskiaheijltjes.bsky.social captures why these rides matter brilliantly. What’s your experience? youtu.be/wmUP8OH50E0?...
- 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
- Y discutible quiere decir simplemente eso: q es algo q hay q discutir (de la buena manera, no al estilo tuiter). Sin embargo es algo q no solo no se trata, sino q se da por sentado sin discusion q cuanto de mas lejos venga la gente a trabajar a tu ciudad, mejor... No es por ahi

- El entorno urbano te manda un mensaje... como usuario sos solo tolerado o estás realmente invitado? Diseñar el espacio para generar los comportamientos q deseamos obtener
- 'Hacer mas práctico y seguro caminar o andar en bici podria hacer mucho para eliminar barreras q nos dificultan mejorar los niveles de actividad fisica y podrian mejorar significativamente la salud de la población urbana' Es cierto en UK y también en Argentina, especialmente en Bariloche

- Se viene hablando mucho de la eliminación de ciclovías en CABA. Sorprenden comentarios de gente q parece creer q con una medida así van a desaparecer los "ciclistas malos" (los q van por fuera de la ciclovía, usan las veredas, zigzaguean entre los autos, etc) q son a los que NO afecta q se quiten
- Si a alguien afecta la eliminación de ciclovias en primera instancia, es a los que LAS USAN. Probablemente mucha de esa gente tenga dos opciones: Seguir usando la bici en los carriles generales (quizas adaptandose a formas mas agresivas) o dejar de usar la bici (pasarse al coche?)

- Reposted by Juan del ValleCar 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. slate.com/business/202...
- Reposted by Juan del ValleNew 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. www.iihs.org/news/detail/...

- Reposted by Juan del Valleeven better, we should build infrastructure that makes bad driver behavior impossible: car free spaces, concrete protected bike lanes, BOLLARDS!! cheaper and more effective than cops or cameras. please consult the Triangle

- Reposted by Juan del ValleOne of the lesser-known legacies from Vancouver’s hosting of the 2010 Winter Olympics was significant transportation mode-shift that could usually take decades. We had to shift 30% of car trips DT during the Games, & specifically planned to keep most of that shift post-Olympics. POWERFUL catalyst.
- Recordatorio periódico de que la velocidad importa... y mucho
- Estos días se aprobó un nuevo plan estratégico de seguridad vial de ANSV (sin bsky todavia?) boletinoficial.gob.ar/detalleAviso... Es más un plan de gestión de la agencia q lo q solemos entender por plan estratégico de seguridad vial y lo aprobado parece su presentacion ppt, pero está interesante🧵
- En el índice más o menos se puede ver todo el contenido de un vistazo:
- Esto es fundamental y muy positivo: redacción (y aprobación supongo) de 1000 planes locales de seguridad vial en todo el pais. Capacitar a técnicos locales y q cada ciudad pueda tomar decisiones en base a lo q pasa en sus calles (en lugar de darles todo hecho desde arriba)

- Reposted by Juan del ValleI actively avoid calling people on bikes “cyclists.” It fuels an “othering” or “us vs them,” and makes it easier to claim that safe infrastructure is for a small in-group. None of which is helpful. It may take more characters in a post, but I just say people on bikes. Because that’s what they are.

The reckless motorist deals more death than the artilleryman. … Immediate action [is necessary] to halt the homicidal orgy of the automobile.”
