Public transportation violence affects mobility.
Women experience more sexual violence, particularly during the access and waiting stages.
Longer walking, waiting, and in-vehicle times increase the likelihood of violent incidents.

BRT uplift (2017) reverses to citywide proximity penalties by 2021.
MRT exhibits uplift, strongest around upgraded stations.
Citywide mode shift in capitalisation from BRT to rail.
Policy: co-locate BRT-MRT, mitigate BRT penalties, time TOD and LVC.

The Other Reason Americans Don’t Use Mass Transit
People will take buses and trains only if they feel safe while riding them.
The American centrist punditocracy has decided that what the US transit industry needs are endless lectures about the importance of security.
These writers misunderstand the problem, and are making things worse. 1/

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.

Happy centennial!
It’s worth noting that originally this body, the first national traffic engineering institute, was funded 100% by one automobile manufacturer: Studebaker. It was named the Erskine Bureau after the company’s president. In 1935 the Automobile Manufacturers Association took it over.

A world without traffic? Three urban experts rethink how cities move
Gridlock is costing us billions, but bold solutions like bus-only lanes, congestion charges and flexible work hours could get cities moving again
NEW: “Toderian says it’s easy to be distracted by futuristic innovations like electric cars, drone delivery networks & hyperloops. ‘The real solutions are a lot less sexy and a lot more common sense… Tech won’t save us if we get the fundamentals wrong.”
I was 1 of 3 urban experts asked to weigh in.
