Signalized intersections

I’ve been trying to come up with a more rigorous heuristic to estimate how many signalized intersections a given geography should have if OSM were complete. Apparently planners typically estimate traffic lights based on population, and it holds up when analyzing metro areas. But for larger or smaller regions, I’m thinking population might not be very reliable, since the actual criteria for installing a traffic light depends in part on traffic volume. [1] After all, an industrial area may have no residents but more traffic lights than a typical suburban residential neighborhood. DOTs publish traffic counts (AADT), which could allow us to arrive at a fairer estimate and potentially a ranking among geographies. – Minh Nguyễn (talk, contribs) 01:24, 8 November 2018 (UTC)

Tornado sirens

I'm also trying to come up with a benchmark for the expected number of tornado sirens in a given region. That's hard to come by, because it doesn't look like anyone has ever conducted a comprehensive survey of outdoor warning sirens in the U.S. The closest I've come is this talk at an American Meterological Society symposium (4:19) that gives a sense of the geographic distribution of sirens in the U.S. – Minh Nguyễn ^💬 17:46, 4 August 2019 (UTC)
