Calcuating Miles of the Speed Limit on Touring Routes
From the department of neat things you can do with a few lines of R code.
library(tidyverse)
library(arcpullr)
arcpullr::get_spatial_layer('https://gis.dot.ny.gov/hostingny/rest/services/Roadways/RoadwayData/FeatureServer/1') %>%
filter(Posted_Speed_Limit_MPH > 10) %>%
mutate(Length = st_length(geoms)) %>%
st_drop_geometry() %>%
group_by(Posted_Speed_Limit_MPH) %>%
summarise(Miles = sum(Length) %>% units::set_units('mi') %>% units::drop_units())
