I looked at it. It's kinda strange. First, I'd really like to limit it to New York State, which would mean four bounding boxes unless it actually knew about NYS boundaries. Second, I see that it suggests a 65 MPH speed limit on an Interstate. My reaction is "Well duh, why isn't this automated?" Are these point reports? Yet we're getting told about a way. I am not sure we know enough to fruitfully change maxspeed on a way because we don't know where along the way the speed limit changed. Right now, it looks like most Interstates don't have a maxspeed by default. Aren't we going to get an error report for every Interstate, given that the default speed limit is 65. I did a quick check in NY, and most of the highways which I know are 65 are marked as 65 already. But as you say, we're unlikely to get lower speed error reports. So if somebody has marked the whole Interstate as 65, then if there's a lower speed close to cities (e.g. I-87 goes down to 55 when you get close to Albany), we'll never hear about it. I'm thinking that GPS logs showing us speed would be far more useful. They would show us speed changes in both directions, up and down. They would show us (with enough data) exactly where the speed limit changes. If there are privacy concerns, maybe stripping out all data for speeds lower than 30mph would preserve most privacy without impacting speed limit discovery. -- --my blog is at http://blog.russnelson.com Crynwr supports open source software 521 Pleasant Valley Rd. | +1 315-600-8815 Potsdam, NY 13676-3213 | Sheepdog _______________________________________________ Imports-us mailing list [email protected] https://lists.openstreetmap.org/listinfo/imports-us
