What you wrote makes a lot of sense to me. However, I would also hope that in a matured self-driving environment, traffic lights would be mapped ahead of time. It's always possible that a traffic light shows up in an unexpected place, but in my mental image of the future, this raises a flag for system management to modify the map of permanent objects.
There is a chance that a powered non-permanent traffic light is found somewhere, a dude walking along the side of the street with a stoplight on his back, and connected batteries. In that case, the police need calling. In machine learning, there are just so many corner cases where best to not try to fully interpret, just call out "dude, look at this thing!"

They are used in the case of roadworks or other short-term disruptions that requires traffic flowing in both directions to share a single lane, in conditions not suited to manual traffic control (i.e. overnight, weekends, long-term works on rural roads). http://www.datasigns.com.au/Products/Portable-Traffic-Lights http://www.datasigns.com.au/Products/Portable-Traffic-Lights
- nradov 8y agoIt's relatively common for road maintenance crews in rural areas to install temporary signal lights during major projects. For example when they close one lane on part of a two lane road so traffic can only move in one direction at a time while the drivers going the other direction have to wait a few minutes.
