Interesting to see that the frequency diagram has been added for Brisbane Metro services.
It’ll be good to see this rolled out more broadly… not that many routes have high enough frequency to allow it yet!

Not sure why they need so many different frequencies during the day! And why the exact times of the day? Round to nearest 15min?
Not sure if it’s just the photo, but the headings being black text on the purple lines has really poor contrast and is really hard to read.
It’s not great in person either.
Yeah, the text on the purple should be white IMO.
I’ve seen those at certain QR stations as well and I don’t know. They look… Weird?
The differences in frequency are a hard thing to illustrate visually.
Personally, I don’t love them either, but I don’t really know a way to better way to show them.
Why can’t they just show how long passengers have to wait until the next Metrobus?
That’s on the PIDs hanging from the ceiling.

As alexjago says, there are different forms of signage to display that.
Frequency diagrams play an important role for services that run to different frequency levels throughout the day, like trains, trams and the (M1 &) M2. For the latter, they are perhaps even more important because you simply couldn’t display an accurate, printed timetable for a service as frequent as the M1 & M2 will be. At 1 service every 3 minutes, it’s impractical to print such a timetable and, lets face it, M1 & M2 would never run exactly to a printed schedule anyway.
Speaking of trams, I think the G:Link probably has the best implementation of a frequency diagram. I think the even, 4 column layout is better than the mismatched jellybeans.

I like the GLink version
Simple to understand and not constantly changing.
Not fussed if frequency changed at 5:33 or 5:32. At 5:30 the frequency goes up

QR have started installing the new route maps as well as travel time and service frequency info at outer stations on the city network.
I only got a photo of these two brand new corflutes that went up a few days ago, however I have also seen others installed last week at various stations which show the frequency that trains depart in peak and off peak (the same general design as earlier examples in this thread just in this dark theme).
I definitely think that frequency diagrams could be a thing for BUZ/High Frequency routes. If people want exact times, they could consult a hard copy/PDF or TL Journey Planner.
Maybe not actual BUZ services that run at a consistent frequency, but definitely for the new BNBN “High Frequency” services (and some existing routes like the 555), where the frequency isn’t consistent and decreases in the evenings.
