In the Access to Opportunities Project we have been working on a database with the distribution of population and activities data for the 187 Brazilian urban concentrations. Preview: population distribution on Rio de Janeiro's urban concentration with the 3 resolutions available.
No Projeto Acesso a Oportunidades nós temos trabalhado em uma base com a distribuição de dados socioeconômicos e de atividades pras 187 concentrações urbanas do Brasil. Uma prévia: distribuição da população na concentração urbana do Rio de Janeiro, nas 3 resoluções disponíveis.
📦 {accessibility} v1.2.0 is on CRAN! This new version includes two functions to calculate inequality measures, concentration_index() and theil_t(). This blog post covers their usage: dhersz.netlify.app/en/blog/p…
📦 A new version of the {accessibility} R package has finally arrived on CRAN with several new goodies! 🥳 This blog post covers the main features of the new version: dhersz.netlify.app/en/blog/p…
{accessibility} v1.1.0 is filled with functions that help making accessibility research more methodologically robust. New accessibility measures, poverty and inequality measures, the ability to consider multiple cutoffs/decay values and multiple travel costs.
By the way, you can see both functions in action in the package website.

@ymaricarneiro is another co-author of the balancing cost measure! Sorry Mari, I swear I tried to find if you had an account here...
On a sudden productive procrastination impulse, I have added the spatial availability accessibility measure, proposed by @soukhov_a, @paezha, @higgicd and @Moataz_MMohamed, to the {accessibility} R package. Check it out: ipeagit.github.io/accessibil…
Please @soukhov_a et al feel free to test it and propose any changes to documentation, parameters, etc etc. I have tested with the paper example got the same results (very minor differences, probably due to rounding, I guess).
36 segundos que valem ser gastos com esse corte. @flaviaol claríssima e didática. Não dá pra fingir que quem estava "se manifestando pacificamente" é inocente, porque a simples presença, reivindicando um golpe, é crime.
#Estúdioi
@flaviaol: "Ninguém que estava ali era inocente. [...] Foram ali reivindicar um golpe de Estado, a abolição do Estado Democrático de Direito. Por si só, isso é o crime ".

📦 {gtfstools} v1.2.0 is on CRAN!
🔗 ipeagit.github.io/gtfstools/…
The most recent version of the package includes a function to validate GTFS feeds! validate_gtfs() wraps @MobilityDataIO Canonical GTFS Validator in a very simple interface.
Using it is as simple as:
library(gtfstools)
data_path <- system.file("extdata/spo_gtfs.zip", package = "gtfstools")
validator <- download_validator(tempdir())
validate_gtfs(data_path, output_path = tempdir(), validator_path = validator)
The result:
