Why do pedestrians in Sydney wait so long at traffic lights? I tried to find out the answer and wrote a blog post: https://jakecoppinger.com/2023/07/shining-a-light-on-the-traffic-signals-of-sydney/

I cover previously unpublished maps of signal timings, ODbL crowdsourced data from a open source website I built, how it costs $200 to buy data on a single intersection from the government, details on signal programming in a proprietary format, comparisons with best practice and more.

@jake Aha it says generally 90 secs, same as Sydney. Funny that, when I'm visiting Sydney it always seems to take ages for the lights to change compared to Melbourne. Must be a psychological effect.
