This has been cross-pos­ted to Sus­tain­able Wel­ling­ton Trans­port.

Great­er Wel­ling­ton Region­al Coun­cil is cur­rently con­sult­ing on the Wel­ling­ton City Bus Review. This is man­dated by the Region­al Pub­lic Trans­port Plan, which requires a review of trans­port ser­vices at least once every five years. The cur­rent shape of the net­work has exis­ted for dec­ades and the city has changed dra­mat­ic­ally in that time. For this review, GWRC has chosen to work with MRCag­ney to pro­duce a recom­mend­a­tion, which brought Jar­rett Walk­er, author of Human Trans­it, into our region.

Although the pub­lic trans­port net­work works, it’s sus­cept­ible to reli­ab­il­ity prob­lems. Wel­ling­ton City Coun­cil has tuned some of the road net­work, gen­er­at­ing more than enough con­tro­versy, and con­tin­ues to look at adjust­ments. The pro­posed routes are a more rad­ic­al depar­ture from the status quo. The basic assump­tions are being ques­tioned. As expec­ted, there have been com­plaints.

Dis­claim­er: this post is my per­son­al opin­ion. Oth­er opin­ions are val­id, but I ask that any points of dis­cus­sion be backed up with rationale instead of just emo­tion. My goal for this post is to encour­age people to voice val­id con­cerns to Great­er Wel­ling­ton. The bus review is not an all-or-none situ­ation, you don’t vote for or against it, and this cer­tainly isn’t my word versus yours. It’s up to each of us to be con­struct­ive.

The most import­ant part of the pro­posed changes is the defin­i­tion of the core net­work and a prom­ise to keep it for the long term. The core routes oper­ate at 15min inter­vals or bet­ter, all day, all week. The goal of this is to take away the sched­ule. In a high-fre­quency net­work, pas­sen­gers can show up and get on, rather than plan­ning for when the next bus may arrive. As Walk­er sug­gests, fre­quency is free­dom. Core routes in the south and east cross over each oth­er, allow­ing for those high-fre­quency ser­vices to con­nect town centres in a way that dir­ect buses can­’t jus­ti­fy.

The concept of con­nect­ing ser­vices is woven deeply into the pro­pos­al. It is prob­ably the biggest change to the bus net­work. Trans­fers are rare with­in the Wel­ling­ton region­al net­work and greeted with any­thing between sus­pi­cion and malice. They are a pen­alty on travel times and dir­ect­ness, and pay­ing for a second tick­et would drive pas­sen­gers away from a ser­vice. How­ever, trans­fers allow for much more effi­cient ser­vice – both cov­er­age and fre­quency – for the same trans­port dol­lar. They also allow for a sim­pler sys­tem over­all; the details of a many-to-many net­work is hard to keep in your head. The counter-argu­ment is simple: “If I only ever use one bus, why should I care about net­work com­plex­ity?”. The answer is also simple: you’re meant to be able to use the whole net­work.

GWRC has indic­ated that trans­fers between buses on the same net­work will be free. Snap­per already handles trans­fers from one bus route to anoth­er for Val­ley Fly­er, so get­ting Go Wel­ling­ton trans­fers in place is simple. Trans­fer­ring between oper­at­ors is harder, but not impossible. People who travel longer dis­tances may be able to use daily or monthly passes across ser­vices until we have an integ­rated tick­et­ing scheme in place, which GWRC has sig­nalled for 2016 (see page 11).

There are a few factors that go into mak­ing trans­fers accept­able. After price, timeli­ness and envir­on­ment are prob­ably equally import­ant. While it’s easy to show that a con­nec­ted ser­vice, includ­ing wait times, may in fact be faster than a dir­ect ser­vice, time spent wait­ing is more strongly felt than time spent trav­el­ling, espe­cially if the weath­er is raging. GWRC prom­ises to provide adequate shel­ter at trans­fer points, which must be large enough to hold a reas­on­able num­ber of con­nect­ing pas­sen­gers. These con­nec­tion points offer an inter­est­ing oppor­tun­ity for nearby busi­nesses to pick up cus­tom­ers. Being on the core net­work has def­in­ite advant­ages, espe­cially on the edges.

Out­side of the core net­work, res­id­en­tial ser­vices can­not run at core fre­quency and should not try. Undoubtedly, res­id­en­tial pas­sen­gers are going to feel put out if their ser­vice fre­quency is lis­ted as lower than present. This was sum­mar­ised quite eleg­antly by a friend. People could­n’t care a less if their ser­vice improves, but they’ll scream if they are any worse off. Fre­quency for the sec­ond­ary and peak ser­vices were derived from tick­et­ing inform­a­tion provided by the oper­at­ors. (See sec­tion 3 in the MRCag­ney report, part 1 and part 2.) There are areas that are truly worse off, but it may be dif­fi­cult to jus­ti­fy the extra costs to fill in the expect­a­tion gap, know­ing the pat­ron­age isn’t there. Walk­er sim­pli­fies the point in an inter­view:

You explain that low-dens­ity sub­urbs must choose between cost-effect­ive trans­it or high-qual­ity trans­it. Why can­’t they have both?

Because the design of the typ­ic­al low-dens­ity sub­urb makes it geo­met­ric­ally impossible. Yelling at your trans­it agency or elec­ted offi­cials won’t change the facts of geo­metry. Once you see that, you can move bey­ond blame and start think­ing about what kind of trans­it is reas­on­able in each situ­ation.

In the face of high­er demand, increas­ing the fre­quency of a sec­ond­ary ser­vice is pos­sible. It’s merely a ques­tion of the high­er pat­ron­age jus­ti­fy­ing the cost of the extra bus and driver.

There is a loom­ing ques­tion of where the buses travel through the CBD. Tra­di­tion­ally, everything runs through the Golden Mile unless it can­not. At peak hour, there are in excess of 120 buses per hour in each dir­ec­tion of the Golden Mile. Aver­aging one bus every 30 seconds, it’s com­mon to see buses queueing as bus-to-bus con­ges­tion causes a minor delay to cas­cade back­ward. While there is room for ration­al­ising bus stop dis­tances and pos­i­tions relat­ing to inter­sec­tions, or to speed up board­ings with tech­nic­al meas­ures, the Golden Mile can­not scale to high­er capa­city. The pro­pos­al aims for about 60 buses per hour along the Golden Mile – most core routes and most sec­ond­ary routes. GWRC has not fol­lowed the pro­pos­al from MRCag­ney to cre­ate peak trans­fer points with the core net­work, opt­ing for com­plete sep­ar­a­tion of the peak buses from the Golden Mile. This is a point of con­ten­tion that I have with the pro­posed changes. Mov­ing peak buses out to the quays leaves pas­sen­gers isol­ated and exposed.

Finally, it is tempt­ing to bring the argu­ment of tech­no­logy into this review. The num­ber of com­plaints about the future of the trol­ley net­work promp­ted Walk­er to write a blog post (see point 4), which was then fol­lowed up with a full post on the issue. I think it’s wrong to let the exist­ing trol­ley lines design the net­work by vir­tue of exist­ing. Lines were moved dur­ing the Man­ners Mall redevel­op­ment and lines can be moved again. I think the issue is to get the geo­metry right. After that, we can argue that trol­leys are worth run­ning. Sim­il­arly, the routes don’t depend on light rail, nor do they exclude the pos­sib­il­ity. That’s the bene­fit of defin­ing the ser­vice qual­ity first. How to imple­ment the ser­vice should always be a sub­sequent ques­tion.

The bus review con­sulta­tion is open until March 16, 2012. Fol­low GWR­C’s instruc­tions about giv­ing feed­back, or write some­thing free-form and send it in. All I ask is for you to be con­struct­ive. We’re build­ing some­thing here.
