To put this in perspective, in the US, adding a principle arterial in a large ubanized area costs between $9M and $35M per mile. (2016 USD)

Makes me wonder if the right answer will be dedicated surface roads with a mix of buses and self-driving cars on them. It certainly seems like transit is overpriced by comparison.

The problem with that is it doesn’t solve the surface space problem, i.e. unnecessary city sprawl and reduced walkability due to 30% of space being dedicated to roads

This is why there's so much of a push for bus rapid transit in my city.

Unfortunately, this has disadvantages as well:

- lack of enforcement for bus lanes

- needing to share travel lanes with personal cars occasionally, making keeping the timetable harder

- low cost also means no long-term permanency. would you want to invest in transit-oriented development around a platform that could go away anytime?

Surface streets are much slower because of pedestrians and intersections. This is more expensive, but also much faster as they don't have to stop for other traffic. When you count how many more people can be on this vs a freeway it is a bargin (assuming people use it )

why can’t “the private sector” compete and do it for less?
