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.

A tarifa zero pode ser uma política eficaz para tirar as pessoas do automóvel privado e usarem o transporte público? A gente mostra que a resposta é não nesse estudo que saiu publicado hoje no @jeem-econ.bsky.social

Los jóvenes disparan el consumo cultural y la tauromaquia se hunde La Encuesta de Hábitos Culturales registra los mejores datos en décadas, impulsados por los jóvenes de entre 15 y 19 años. La tauromaquia cae 2 puntos, un 20% menos de espectadores que hace veinte años

Los jóvenes disparan el consumo cultural y la tauromaquia se hunde

La estrategia estatal por la bicicleta es una cosa que se pone en un Word luego en un PowerPoint, luego se vuelve a pasar del PowerPoint al Word... y así pasan veinte años. Lo mismo ocurre con las plataformas reservadas al transporte publico en los accesos a las grandes ciudades, peajes urbanos...

DOGE Put a College Student in Charge of Using AI to Rewrite Regulations A DOGE operative has been tasked with using AI to propose rewrites to the Department of Housing and Urban Development’s regulations—an effort sources are told will roll out across government.

Last night was a hectic one. In case you missed it:

DOGE put a college student in charge of using AI to rewrite housing regulations. Because who needs experts when you’ve got ChatGPT and an economics and data science major?

And yes—this may be rolling out across government. Cool cool cool.

Mientras en París peatonalizan 500 calles y reemplazan 10,000 parqueaderos en vía por espacios verdes e infraestructura peatonal, en Barranquilla seguimos aumentando el número de carriles para carros y motos y construyendo parqueaderos en la vía.

La cuesta arriba de Char para conseguir que los bancos le presten plata El año pasado, Barranquilla obtuvo menos del 40% de los desembolsos bancarios que proyectaba, como parte de su apuesta por hasta tres billones de pesos en nuevos créditos.

"El año pasado, Barranquilla obtuvo menos del 40% de los desembolsos bancarios que proyectaba, como parte de su apuesta por hasta tres billones de pesos en nuevos créditos.

El gobierno de ⁦Alejandro Char⁩ no la ha tenido fácil con los bancos."

Imagínense un mundo donde todos puedan tener su lavadora en la calle, de forma gratuita, sin importar cuánto la usen, y tendrán una idea de lo absurdo que es este mundo nuestro dominado por los carros.

En Barranquilla los andenes son para los carros y no para los peatones:

There’s more than one way to create a liveable city.

What Dutch cities like Utrecht have accomplished through cycling, Swiss cities like Zürich have through public transport: 1.4 tram rides per resident per day, representing 65% of all journeys; and cars just 17%.

These are simply means, not ends.

El monto de dinero fresco que está pidiendo Milei al FMI de forma desesperada suma cerca de 6.000 millones de dólares, pero es que en apenas 10 días Milei se ha fundido más de 1.600 millones. Es fácil calcular lo poco que puede aguantar Argentina incluso con este rescate.

¿Cómo hace un peatón para cruzar en la intersección de la calle 98 con la vía 40?

¿Por dónde debe circular un peatón? ¿Por la calzada?

¿Y los ciclistas cómo hacen?

¿Y si hacemos infraestructura para todos los actores viales y no sólo para los carros y las motos?

Camino todos los días de mi casa a mi lugar de trabajo y no me deja de sorprender lo hostil que es Barranquilla con los peatones. Los andenes (cuando existen) son muy malos, no hay cruces peatonales seguros y los carros circulan como si quisieran matar a alguien.

This guy wants the AfD to win in Germany.

He wants Pierre Poilievre and the CPC to win in Canada.

I don’t know about you, but given the devastation and fascism he’s doing everything he can to create in the United States and beyond, I wouldn’t vote for someone this guy likes in a million years.

En Barranquilla aplicamos al pie de la letra los principios de la movilidad NO sostenible:

- Agregar más carriles para los carros y las motos
-Construir parqueaderos (gratuitos) en la via
-Reducir los espacios peatonales
-No construir ciclo infraestructura
-No dar prioridad al transporte público

Para los libertarios, lo ocurrido en Argentina no es ni un delito, ni una estafa, ni un error. Es la ideología libertaria en acción: mercados sin regulación ni control donde unos cuantos con información privilegiada se enriquecen a costa de otros.

Me parece muy curioso cómo los grupos de derecha terminan apropiándose, de alguna u otra forma, de símbolos del estallido social de 2019 y 2021 que de alguna forma fueron efectivos.

Ahora transformaron las ollas comunitarias en sancochos colectivos.

Pequeño hilo 🧵👇

Since 2010, road deaths have decreased by 5%.

Road traffic deaths fell slightly to 1.19 million per year in 2021.

Over half of the UN Member States saw a decline in deaths, with 10 countries reducing deaths by 50% in the last 10 years. This proves that a 50% reduction in a decade is POSSIBLE.

1% of the vehicles but 3 times the risk of death. Low-income countries are hardest hit by road traffic deaths.

Road deaths are PREVENTABLE when countries put people & safety first:

✅ Ensuring a safe, efficient & sustainable mix of transport types, incl. mass public transport
✅ Protecting the safety of pedestrians, cyclists & other vulnerable road users

Hoy es un buen momento para recordar que, para Milei, una ley de tolerancia cero a la conducción bajo los efectos del alcohol es "cercenar la libertad de los individuos".

Las políticas libertarias ponen en riesgo la vida de las personas. No podemos mirar para otro lado.

How Helsinki and Oslo cut pedestrian deaths to zero After years of committed action, neither city recorded a single pedestrian fatality in 2019

“They cut speed limits, changed street design, removed space for cars… Now it appears that work is paying off. Oslo & Helsinki are reaping the rewards of committed action on making their roads safer, reducing pedestrian fatalities to zero last year.” #VisionZero #SpeedKills #Oslo #Helsinki

Hipocresía radical “Cambio Radical ha sido patrocinador de avales cuestionados que han permitido al clan Char consolidar su poder en el Caribe”: Laura Ardila

A visual representation of global temperature change from 1900 to 2100, illustrating past and projected warming relative to 1850-1900 levels. The timeline includes historical data up to 2020, where temperatures were about 1.1°C warmer than pre-industrial levels. Future temperature changes are depicted under different emissions scenarios: very high, high, intermediate, low, and very low. The color scale ranges from blue (cooler) to dark purple (warmer). Human figures show the expected lifetime temperature exposure for individuals born in 1950, 1980, and 2020, reaching 70 years of age in 2020, 2050, and 2090, respectively. The diagram highlights how future climate conditions depend on present choices regarding climate change mitigation.

No one alive will experience a better climate than today. But young people will experience a much more dangerous and chaotic world in the future, and the extent to which that happens will depend on our choices today. Trump doesn't care because he's old and a sociopath.

La dependencia del automóvil en Estados Unidos no fue producto de la demanda masiva, la democracia o la libre empresa, sino de políticas públicas destinadas a promover el uso del automóvil.

Car dependency in the US was not the product of mass demand, democracy or free enterprise.

This means that mass demand, democracy and free enterprise are no obstacles to the better future we need.

1. Milei, efectivamente, es un estafador. El cómplice de unos trileros que han ejecutado el viejo timo de la estampita: recibir el dinero de unos amorales codiciosos a cambio de un sucedáneo sin valor.
