    Even with single people in cars you can move wayyyy more than 100 people per hour in the top left.

    Assume 25 mph speed and 30 feet between cars, each car crosses 30 feet in about a second. 3600 seconds in an hour, times 2 for both directions and you have 7200 people that can move on that little road.

    Now add additional passengers…buses…it can move a decent amount more. There’s lots of reasons cars suck but let’s not make up math to prove the point.

      It’s not saying that the top row can support at most 100 people.

      Just that if you have 100 people per hour, you need something like what’s in the picture. The train tracks aren’t being fully utilized in the top pic, either.

      As an aside, you’re forgetting that cars are ~15 feet long on average. So you’ve got an hour of traffic with consistently 1 car following distance, which is fairly unrealistic. Real world capacy of a lane is closer to 2k people per hour, or 4k both directions.

    As always, the problem with commuter trains is the last mile. If you work in the city, there is probably some form of bus or subway, but if you work in an unwalkable suburb, you’ll need an Uber for that last mile which cuts into the benefit.

      surely you can bike 2 miles in the burbs? One of the upsides of suburbs being so painfully sprawly is that barely anyone lives there, so you shouldn’t have a tremendous amount of traffic on those 2 miles to the train station.

      And even if you’d fear for your life biking there now, it’s not like you need to build bike paths along every little residential street to fix it, start with the largest most high-traffic roads and build your way down until people feel safe biking to the train station.

        Sure, but then you have to carry your bike with you on the train. There is no workable solution to suburbia that doesn’t involve cars because it was designed and built around them. Unfortunately, they’re now home to tens of millions of people, and any quick solution would most likely end up hurting a lot of them.
