UBC line rapid transit act 2

Post updated on April 6th
As mentioned by Stephen Rees, I was at “a special blogger breakfast” about the project where Jeff Busby and Margaret Wittgens from Translink provided a description of the different options and was answering our questions . Translink has provided significantly more material in this phase than in phase 1.
The consultation process
Like in Phase 1, translink has scheduled several workshops. In those workshops, Translink staff engage conversation where you have the opportunity to discuss your concerns, opinions not only with staff but also with your ‘neighbors’ and understand others viewpoints. It is a very constructive approach, and I warmly recommend people to attend those workshops and provide feedback as soon as possible in the process to Translink.
In the preliminary phases, it was unclear what Translink was meaning by “LRT”, an LRT in the American sense, or a tram in the European sense? A later solution apparently favored by noticeably UBC professor Patrick Condon and a relatively active Broadway merchant group called BARSTA.
- The Phase 2 gives a clear answer: the option is an LRT in the american sense.
Compared to the “business as usual case” (assumed to be the bus 99B)  the cost required to attract additional ridership is around $25,000 per new rider, as suggested by the graph below comparing the different solutions proposed by Translink
That is, the additional ridership could be at the expense of local bus routes, so if the goal is to increase the Transit mode share, and that is a goal of both the Province and the City of Vancouver , the figure become more striking, and solutions providing net gain time on the Commercial Drive to Central Broadway seems at a net advantage in term of “buck for the bang”.
Some solutions provide clear advantage in time of access time from Commercial to Cambie, and convenience from the Millenium (lack of Transfer), over others; and at least from the cost/additional rider perspective, looks reasonably priced. Obviously it couldn’t be the only metrics to look at…among others are the travel time to UBC , operating cost…
Under this regard, the lately added Combo 2 , RRT+BRT, could require more refinement:
The redundancy of service East of Arbutus doesn’t seem to provide the bang for the buck, noticeably in term of serviced area. We could have preferred something looking more like the rubber tire version of Combo 1 or looking like the figure below
The regional perspective
That is, as reported of this week workshops, and already outlined here, it is hard to ignore the regional significance of the connection of the Millennium line to the Canada line, which could have a “shaping” effect probably as great as if not greater than an extension of the existing Skytrain in the confins of the GVRD.
A discussion has been engaged by Stephen Rees on the trip model used to generate ridership. It appeared that Translink consider the Evergreen line built in its modelling. That says, they also rely on growth projection provided by external agencies; and this growth projection could not have considered a transit network effect
The network effect
On this topic, Jeffrey Busby mentioned that the scope of the study is really the Broadway corridor, and not addressing the question of the “extension” or not of the Millennium line.
- According to the selected option, this question could be still open, leaving customer of the Millennium line to their frustration for very long time.
In that sense, an apparent cheaper solution, not based on an extension of the Millennium line could prove to be a costly mistake, but obviously all of that need to be quantified and LRT could make sense at least on part of the corridor
 The choice to prefer to compare travel time between Commercial and central Broadway rather than UBC is deliberate since UBC bound riders, mostly students, could be less sensitive to travel time than the more general users.
