For fixed route transit, speed is latency. The faster the bus can make the average trip, the tighter the timetable can be given the same number of buses. Fewer stops also improves consistency which means you can plan to arrive at the stop closer to the scheduled time, and timetables can be tightened even more by reducing the layover times that keep the bus synchronized with the time table.
replySeparately, the variability problem can be somewhat solved with the real-time location updates that many agencies provide. You'll still have to wait the same amount of time, but some of it can be done comfortably in your house when the bus is running late.
It helps with latency too or schedule padding. Bus schedules are unreliable because of all the stops which slow them down and encourage bunching of busses on a route with a lot of service.
replyBus bunching is often blamed on traffic or scheduling, but in my experience in NYC, a lack of enforcement and/or accountability plays a role too. I live near one end of a bus line and commute to the other end 5 days day a week. On a daily basis, there are large gaps where buses miss their scheduled times. Then, as they approach the end of the line, they arrive and depart in groups of three or four, which only worsens the problem.
replyFor a fixed number of busses, the faster the busses are traveling the less time there is between busses.
