Northern Beaches BRT study released

Bus Rapid Transit (BRT) has recently been studied for the Northern Beaches.  Long story short, it finds that none of the studied concepts is cost effective.  Why might this be? 

1. 24 hour bus lanes are a bit wasted if off peak services are to be kept mediocre.  I mean, for crying out loud, 20 minute weekend frequency on the L90 (to Palm Beach) dropping back to half hourly evenings and early mornings, with the L88 (to Avalon) not operating is mediocre at best.  In general, 15 minute frequency is what is needed to boost patronage as a 14 minute wait is far more acceptable than a 19 minute one.  Similarly, the L80 (to Collaroy Plateau) reverts to a half hourly 180 on Saturday and the L85 (to Mona Vale via North Narrabeen) is also half hourly.  Those heading beyond Burnt Creek Deviation are best off to avoid the all stopping services as they are about 8 minutes slower from Wynyard to Condamine and King Sts, so effectively there are only 5 buses an hour on this corridor Saturday daytimes with 20 minute service gaps, speaking generally.
2. A 6 lane Spit Bridge is hard to justify as there are already 3 lanes for the peak direction.  This does prevent the limitation of needing to reduce to a single lane counter peak, but it is easy to see that not being justified.  The Roseville Bridge is a reasonable alternative for counter peak travel for half of the Northern Beaches.
3. Option One seems to include the removal of the tidal flow arrangements on the Spit Bridge, with a single lane for cars in both directions.  This is not made clear however.
4. The suggestion of removing the L60 (Chatswood-Mona Vale via Dee Why) is bizarre.

What are alternative proposals? 

1. Have a counter peak bus lane along Spit Rd, preferably extending all the way back to the Warringah Freeway.  This likely would need to be combined with pushing trucks into lane 3 from the start of the Truck and Bus Speed Limit shortly before Medusa St.  There are no right turns until the end of the current speed limit, even if there is one immediately after its end.  This bus lane is important as it allows buses to queue jump the counter peak traffic letting them both serve the counter peak demand better and return for another peak run without requiring more buses to provide the same service.
2. Upgrading the peak direction Transit Lane to a Bus Lane between the Spit Bridge and the Warringah Freeway.
3. Actually establishing some sort of PM peak priority north of Ourimbah Rd.
4. Increase off peak services.  BUZ in Brisbane and Smartbus in Melbourne have both seen high take up of their services.  Metrobus in Sydney has been less successful, even if there are good services in there.  Services stopping at 9pm is no doubt a factor in the lack of success of Metrobus.  This would do much to reduce traffic congestion on the beaches and also help justify 24hr bus lane proposals.
5. More limited stop services outside of peak hour.  It is unclear why the L80 should downgrade to a 180 on weekends, for example.
6. Free transfers.  This will improve the service for all in that people can use a feeder and trunk model to get faster journeys.  Some will prefer a slower single seat, of course.

More generally, it is not entirely clear why median stations would be preferred over kerbside stations, nor is it clear why North Sydney termination with interchange to what are already reasonably full trains would even be proposed.

None of the options in the report break down the costs into their components, largely leaving the reader guessing.

Cityrail timetable proposals in recent news - Part 2

It has recently been announced that the promised plans of double deck services from the North West all the way to the CBD are to be revised.  They are going back to a North West metro, single deck, and only running as far as Chatswood as a first phase.

Firstly, this means that the upper Northern Line will need to revert to running via Strathfield.  Unless it is going to take paths through Town Hall platform 3 from the Western Line it will also mean that the upper Northern Line will terminate at Sydney Terminal.  The only question raised with this is if there is enough capacity between Redfern, Central and Town Hall.  Well in the AM peak 4/6 Bankstown line trains add to this capacity.  This should be relatively simple to expand to the other two with a timetable review.  This capacity should be relatively easy to provide in the AM peak, and the PM peak is far less congested.  Reversing the direction of the Bankstown line around the city circle full time may well be a reasonable option, as might Melbourne weekend style Bankstown-Town Hall-Museum-Bankstown full time.

Secondly, it means no expansion to Railcorp and in fact a slight contraction as they will be removed from the Epping-Chatswood Rail Link.  In my opinion, this is real positive to the proposal.  I'm really not sure how long we can go having Railcorp consume $3 billion per year and rapidly rising.

Thirdly it means an interchange at Chatswood for trains which are allegedly already full.  However, they aren't as full as trains on other lines and the upper Northern Line passengers are to be removed from this patronage.  It will also be possible to increase the numbers of trains on the North Shore by up to 6 per hour.  There will be plenty of capacity for passengers from the North West who will have a cross platform interchange at Chatswood, much like Glen Waverley line peak hour passengers in Melbourne who need to interchange at Richmond to reach city loop stations.  Hardly the end of the world.

All in all the first phase of these changes is quite good, which is something I will not say about the second phase in my next blog post.

Patronage figures from Parliament

The answer to a question about bus patronage through the Maroubra electorate, gives us some interesting data to work with.  I do not know why the 391, X92, X10 and X77 services are not included.  From 1 January 2011 through 31 May 2011:

Route	Total Boardings	Average boardings per trip
X99	12849	62.99
400	2095048	62.40
X97	12721	62.36
410	174711	59.06
M10	969263	57.60
X94	116513	54.39
392	599207	52.23
X96	52035	51.01
399	473531	46.79
395	401209	45.40
310	605740	44.74
397	388824	43.22
L94	473473	42.70
M20	729273	42.42
393	963762	41.15
396	475910	40.82
309	769593	40.61
394	378437	40.14
317	230617	36.36
376	315198	35.36
301	459514	35.30
X09	33289	32.64
353	288094	32.28
377	400737	29.93
316	172973	29.17
302	71180	28.98
L09	45463	27.86
341	63	0.15

A few conclusions seem possible from the above data:

1. 392 corridor is under serviced.  This picks up 3 trip generators - Eastgardens, UNSW and the CBD so it is possible that a number of trips see spaces occupied more than once, but even so it seems an upgrade is justified.  I would go further and say that the 392 trips should all be converted into an L92, serving L94 stops between the Kingsford nine ways and Museum, running every 15 minutes until 11:30pm 7 days a week.  The L94 should also provide the same level of service.
2. 341 could presumably be more cheaply served by some sort of para transit on demand service.
3. 316 under achieves.  It could be better removed and converted into 317 trips and improve the legibility of the service.
4. 302 under achieves.  It is noted that while this serves UNSW, Eastgardens and the CBD it seems that people don't find the service very attractive, in spite of all the destinations served and the low frequencies of the alternatives.  The route could be reviewed and perhaps folded into the 303.  Serving Central would be sure to increase the potential patronage.  There are some 303 short workings from Todman Ave to Botany, which suggests a Botany terminus could be more desirable, although I am not sure why.  Alternatively, the marketing could be the problem.
5. 376/377 corridor does not justify two routes.  If there was integrated fares, there would not need to be two routes - via Central and via Oxford St.  Those going to Central would be able to interchange.  As a former user of the common part of the 373/377 corridor, I can report that the majority of the 377 patronage comes from the common part of the corridor.
6. X09 seems to under perform.  This seems to be mostly due to train fares to Green Square station being reduced.  This route has since seen a 20% reduction (-2 trips in the PM peak), as with the X10.
7. M10 and M20 perform arguably satisfactorily.

Without the M20, there would be no connection to Central for Bourke St and the upper end of Joynton Ave.  If the M20 is to be removed, such a connection should be provided in another way.

The L09 operates counter peak only so if it isn't collecting passengers it would be dead running anyway, so I have no concern about that one.

An alternative to the proposed L92 would be an L96, based on the argument that between the 395 and 396 Maroubra Beach is busier, but that ignores the patronage which would be generated by the frequency increase as well as the patronage from the 391, which is unknown.

Basic problem is that there are insufficient service kilometres in Sydney outside of peak hours, even if this is the least severe in the Eastern Suburbs.

New Cityrail timetable for 2013

Last month a new Cityrail timetable was promised for introduction in late 2013.  What should it contain?

1. Increased Cumberland line services.  Only 5 per day apparently well utilised services is a bit of a waste of the infrastructure built.  It also reduces the incentive to put jobs into Parramatta.  The Epping-Chatswood link is given credit for Optus moving into the Macquarie Park area, but the lack of service on the Cumberland is somehow not thought responsible for the low growth in jobs in Parramatta
2. Extension of the current Chatswood terminators from Hornsby via Macquarie Park somewhere.  Not reaching the city results in these trains being under utilised.
3. Increase in Parramatta's off peak service.  4 low speed trains per hour off peak is a poor service for such a major centre, not counting Blue Mountains trains.
4. Remove Campbelltown via Granville and have a minimum 15 minute frequency for Campbelltown via East Hills and Airport.
5. 15 minute all day frequency for the South Line - currently this drops back to half hourly in the middle of the day weekdays and evenings.
6. 15 minute all day frequency to Penrith.
7. Removing city to Liverpool via Regents Park trains thanks to utilising the Lidcombe turnback.
8. Further rationalisation of stopping patterns.
9. Faster trains.

What is it unlikely to contain?

1. Increased Illawarra line trains - some say that it isn't possible to increase this while freight is still operating on the 2 track between Hurstville and Sutherland.
2. Increased Epping via North Strathfield trains, both at peak and off peak.  Increasing the peak trains would require either trimming Western Line trains or increased running into Sydney Terminal.  Increasing off peak trains seems relatively unlikely, perhaps because it would make it harder for freight to connect with Flemington.
3. Increased trains to Berowra - these have conflicts with freight and interurbans which do not apply for Hornsby terminators.
4. 10 minute frequency (or better) on the Inner West and Bankstown lines.
5. Bringing back Parramatta via Bankstown trains.  These trains are a conflicting move nightmare, and it isn't entirely clear that it is so necessary to encourage those living from Berala to Erskenville to work in Parramatta as opposed to the CBD.
6. Something to connect the Carramar to Sefton stretch to Parramatta, at least in peak.  The M91 does connect Chester Hill.  Otherwise it will be in necessary to double interchange at Birrong and Lidcombe or Cabramatta and Granville or single change at Cabramatta.
7. Faster trains.  Witness the slow downs which have recently been announced for a couple of trains on the Newcastle line from 18 June 2012.
