Origin-destination data (and route patronage data)

[aldonius]

I discovered that TransLink published origin-destination data aggregated by month for February to October last year:

Thanks.  Next question why has publication stopped?

October coincides with the commencement of #RailFail...

Is that in terms of passenger loads?  I know from personal experience, the Bay Islands ferry does get full loads as it's the only way to/from the islands and the mainland and each ferry can carry quite a few seats and standees (can't remember how many off the top of my head but it's gotta be at least more than 60 seats I think?)

With the October file, I got numbers that were what I was expecting: 12M trips for the month.

And the top 20 "routes" according to the same data:

Hi, the data does not make a lot of sense. It is suggesting that route 184 carries more passengers than the second most popular bus route in Brisbane the route 199.

And apparently, route 125 is even busier? Difficult to believe!!

Not so hard to believe metro if your a regular Ipswich rd user.
Even in competition with the 110,115,100,116....It regularly has standing loads evenings and on weekend afternoons...both days...its the all stops factor...lots of elderly use the route solely for that factor........both the 124 and the 125 get packed pm peak outbound......probably wont be long before we see the first 'sorry bus full' 125.....the Ipswich rd walkup patronage has gotten progressively busier since 2013 due to gentrification around westend,south brisbane,wooloongabba,buranda where a lot of low income earners have moved to places like Dutton park,annerley,moorvale etc.
The route is also carrying a lot between Gcity and Griffith uni...

306 ranked higher than a 330/333/340/345........

I've got aggregate route data (from a pivot table). The route rankings are exactly what you'd expect. I'm not sure how OzGamer did their analysis.

nice aldonius.......that list more accurately reflects the popularity of each route!

125/174/175 ahead of the bulimba routes 230/235.....I would have expected more from those 2 routes.....

buz the 314!

buz the 314! 

I'll second that!

[aldonius]

I've done March as well for comparison (March is usually the busiest time of year in Auckland and we're pretty similar).

And it was busier then - more like 14 million trips for the month.

take a look at the numbers its getting vs number of services(frequency)...no wonder its up there....its performing better than the 110,230,235 and they have much higher frequency

I have no idea; I don't think it's supposed to exist...

I think it's a Noosa free bus route.

Apologies for my not looking at the data structure more carefully and causing confusion before. Nothing to say but that I was insufficiently careful - sorry! Here are the top twenty routes. Unfortunately the Go Card data can't separate train lines but it's here for interest. Good to see that the GCLR is much busier than any individual bus route.

Rail	3,544,817
GCLR	672,239

^ concerning omission from that list is no old Cleveland rd routes. Clearly shows the cannibalisation/duplication issues.

They're pretty close behind:

I think what would be more interesting would be the routes ranked #21-40. This would tell us any good BUZ candidates as well as any BUZ routes which aren't pulling their weight.

21-40

Most of these are either already frequent routes or largely share corridors with frequent routes. The only quite separate ones that might be suitable for upgrading seem to be the 300 and the 174/175, although the latter are somewhat overlapping with the 170. The 170 itself is down on 28,894.

Interesting seeing the AM and PM peak spreads in some routes, especially the rockets

136 AM 3645 PM 1930
153 AM 4410 PM 2076
156 AM 14532 PM 4718
162 AM 5112 PM 2757
P157 AM 2778 PM 5398

I assume city stop locations + fewer services would be why these routes are generally less used in PM peak.

and no inner waterworks rd routes on that list either. Clearly shows that the corridor isnt worthy of buz just yet for varying reasons from vehicle traffic flow to terrain.....there basically needs to be far more on-street development for it to get anywhere near buz patronage levels.And/or passing directly to a university.

^ Hardly.  You would need to look at corridors to make that kind of call.  It would be like me claiming the 700 is about as busy as the SEB because it carries around the same patronage as the 111.

[#Metro]

RBOT has a model of both the current BCC bus network and a proposed New Bus Network.

You can use the RBOT Model of the BCC bus network to see which buses are on which corridors

RBOT Model of BCC bus network: http://tiny.cc/checkyourbus

What I can see is that there is definitely room for a BulimbaGlider.

Using Aldonius data sheet (thank you, link in OP above) we can look at what the patronage would be if the 230 and 235 were combined.

230 Inbound - 24192

230 Outbound - 17772

235 Inbound - 14881

235 Outbound - 17963

Total: 74,808 (Assuming no growth)

Now we know that when we double the frequency, we essentially double the patronage.

BUZification would bring that patronage up to 149 616 (so essentially 150 000)

That would be comparable to what the BUZ 333 or 111 carries.

Would it be possible to get a list of just the top twenty 700 series routes?

If you go to the 'Totals' tab of the spreadsheet at the link I posted a page ago, it should be filtered to only routes starting with a 7 and sorted by descending patronage.

Sweet Awesome, thanks for the effort.
It has caught up to June 2017...how readily can you do full year performance?

Is there much involved with formatting the data?

Finally Bob, this thread totally deserves to be pinned at the top, its a very useful go-to.

• Tweet

[aldonius]

From memory, the initial data crunch is just a pivot table in libreoffice. Shouldn't be overly difficult

• Tweet

[Gazza]

No worries...I can sort of see how it works...each route has stop IDs, but you'd just combine all trips under a certain route number into one.
dont really know enough about data processing to do it properly though.

Is the data laid out consistently enough that you could do a merge of the twelve monthly sets into a 15-17 FY summary table?

This is gold!

• Tweet

[aldonius]

It should be laid out the same way each time. Why would they change it?

Summary table should be doable. Don't know when I'll have it done, though.
