The typical general-purpose lane of traffic in a city can carry around 1,000-2,000 people per hour. If you create a bus-only lane, that number jumps up to 4,000-8,000 per hour. If you give over more of the street to transit and create a transitway that goes up to 10,000-25,000 people per hour.https://99percentinvisible.org/episode/missing-the-bus/
