Full Version: What causes bus bunching on the new BRT line during my commute?

So I’ve been taking the new BRT line on my commute for a few weeks now, and honestly, I’m a bit torn. The dedicated lanes are great when they work, but I keep hitting these weird gaps where the buses just seem to bunch up for no clear reason. It feels like the schedule is more of a suggestion some days. Has anyone else noticed this, or is it just my timing?
I ride the BRT line too and yeah the gaps are maddening. It speeds along when everything lines up, then you wait and it feels like luck more than a schedule.
That’s classic headway variance in action. If one bus slows at a stop or another runs early, the rest bunch up and the next gap grabs the whole corridor. Even with dedicated lanes, timing and dwell times can screw with the plan.
I thought it was the traffic or the sensor timing, but on some days the BRT just seems perfectly paced. Then the next day it’s a different rhythm and you’re left recalibrating your expectations.
Maybe the real frame here isn’t the schedule but our assumption that reliability equals perfect timing. The BRT can be fast, but if you’re chasing one bus in a line you’ll notice the fragility of the system more.
I’m skeptical that a BRT line can magically fix all transit headaches. When a bunch of riders shows up at the same time the headway shrinks regardless of lanes, and you end up waiting anyway.
If you’re writing about the BRT experience, lean into the details: the hush between stations, the push of the crowd at doors, the variance in dwell time. That texture is what makes the promise of a faster line feel earned or not.
A useful concept here is headway variability; it’s not a conspiracy, just the math of how buses space out. It shows up as gaps and clusters even with a nice BRT lane grind.
