Removing unnecessary bus stops is a prerequisite to making busses fast. You can't run a fast bus service if the bus is stopping every single block.
- oblio 8mo agoThere are 2 big prerequisites for fast bus service : 1. Dedicated bus lanes (speed, predictability). 2. Traffic light priority ( speed, predictability). How many US cities implement even one of those?
- adgjlsfhk1 8mo agoNot nearly enough
- angmarsbane 8mo agoDedicated bus lanes that are physically separated from car traffic specifically, like the BRT system in Mexico City.
- connorboyle 8mo agoRegardless of exclusive RoW or signal priority, it is physically impossible for a bus route to: 1) stop every few hundred feet to pick up and drop off passengers 2) maintain an effective speed significantly faster than running
- thomastjeffery 8mo agoThat optimizes speed, not latency. I don't care how long it takes to get off the bus nearly as much as I care how long it takes to get on.
- enragedcacti 8mo agoFor 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. Separately, 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.
- paddy_m 8mo agoIt 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.
- tartoran 8mo agoBus 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.
- adgjlsfhk1 8mo agoFor a fixed number of busses, the faster the busses are traveling the less time there is between busses.
- thomastjeffery 8mo agoRight, but for a fixed schedule...
- adgjlsfhk1 8mo agoSchedules get adjusted based on budgets. Faster busses yield better schedules.
- janalsncm 8mo agoThere already are “express” buses that don’t stop at every stop. They don’t solve the issues I described above. Cutting the time between bus arrivals would be a much more effective solution.
- blainelewis1 8mo agoMaking buses faster can improve frequency though, and it's likely cheaper to improve frequency by making them faster than buying and operating more buses. The speed is almost directly correlated with the interval between buses, going 20% faster means ~20% less time between buses.
