10 Minute Max
Basically, the 10 Minute Max system is a network of all-day buses and trains that run at least every ten minutes. Jarrett Walker says, "The idea is going to spread for the best of reasons: because it's such a simple and powerful idea."
"10-minute frequency is an impressive threshhold. Even Los Angeles uses 12 minutes as its cutoff, and 15 is more typical. The duration, 6:00 AM to 9:00 PM, is also impressive."
