Where was this mile-long stretch? 3rd street?
- saagarjha 3y agoYeah San Francisco has some of the best traffic lights in the Bay Area when it comes to predictive signaling and synchronization
- dekhn 3y agoand for a long time you could drive on Great Highway at 35MPH and hit green at every single light. Always enjoyed that except that I would have preferred 50MPH
- esoterica 3y agoIt should be illegal to drive above 25mph on any street that pedestrians regularly cross (i.e. all urban non-highway roads). Your enjoyment of speeding does not supersede other people’s right to not get struck by a car going 50mph.
- dekhn 3y agoThis was not a necessary point to make, as I merely expressed a preference. And the law isn't going to be changed to accomodate your desires.
- wsinks 3y agoI'm not arguing with you, but is there any documentation of SF's predictive signaling and synchronization and how it's the best?
- saagarjha 3y agoI don’t have any, unfortunately. This is just anecdotal from driving around.
- jiveturkey 3y agoinductive, not magnetic
- ignormies 3y agoAs an extension of the argument the comment you're replying to was making: Many (most?) intersections in the Netherlands have early detection systems that change the light _before_ the car reaches it. But they didn't just do this for cars, they also do this for bikes. And public transit gets signal priority allowing buses and trams to almost always get green lights. They've spent the money improving transportation of all forms, not just cars.

- JanSt 3y agoAs a german I'm so jealous for the smart actions of our neighbors. We are always at least 10 years behind.
