Why cant we have smart stop lights. Nothing more annoying than sitting on a street with nobody coming and a red light for some arbitrary time period that's totally incorrect for the time period I'm currently in

They exist. Your city needs to set it up. They can also switch to flashing red lights.

>During “treatment” days, the modified routing guided all trips that encountered the pre-selected congested segments toward alternative routes with similar travel times. Why would they specifically need to route people away from congested segments? Presumably if a segment gets congested enough, it'd be considered slower and therefore won't get picked in the first place?

Another question: they say road speeds increased, great. But that’s a different metric than average drive time. Curious if that also decreased.

Congestion can be solved by charging more for driving. Even a modest amount would start affecting how much people drive. The money could be used for better roads and improving other transit options that aren't so space-inefficient. That said, this would likely be unpopular to implement until the effects were visible. See congestion pricing in NYC as an example.

I read the article and didn't see anywhere if they collaborated with city planners, or just ran this on their own. I get the techno-optimism of making traffic 'better' and also it may be concerning if trucks are being routed through neighborhoods where planners didn't build for it.

If we could copy the traffic laws of a country like Germany to the US, I think that would have the biggest + cheapest effect. I am OK with automated/elevated enforcement if it means stop & go traffic evaporates into free flowing conditions. We should also take the idea from Finland where the traffic fines scale with each person's ability to pay. $100 for camping the passing lane or failing to maintain a reasonable fo…

I wish there was more police presence to spot lane-camping and fine them in Germany, too many idiots do it and get away with it.

If I ran Google Maps, I'd ask to route stupid drivers away from my routes. The GPS and phone accelerometer should be able to tell us who they are -- "Oh you have Google Maps actively navigating, GPS says you're going 50mph, and the app in focus is WhatsApp and you're using the phone keyboard? Fuck off! Also we recorded 5 swerve events in the last 10 minutes, hard to stay on your lane when you're texting!"

It'd be unethical, but man it'd be magical...

There's custom software for Elon's Tesla, I wonder if the cloud-based navigation system also directs people away from his routes so he can have a ride on emptier roads...

Found the European :)

Traffic apps only know about congestion if someone running the app goes down the congested road. Because of this, I've always suspected that the apps, from time to time, will route someone down a route they haven't gathered data on in a while, just to collect the data, and even if the route is likely to be suboptimal.

There's probably enough people taking wrong terms (such as me) to provide enough data. ;-)

The south SF Bay Area cities of Los Gatos and Monte Sereno have persistent problems with traffic gridlock during summer weekends and holidays due to navigation apps routing drivers off of southbound SR-17 and onto surface streets. It gets so bad that residents literally can't get out of their own driveways and emergency response vehicles can't move.

There actually did used to be train service from San Jose to Santa Cruz but it was abandoned in 1940 due to high costs and lack of use. Rebuilding it would cost >$1B.
