Hmmm, it is true, Andrew Haydon’s article is not a detailed engineering document, but what is the audience it is aimed at - the general public who has not necessarily been following the whole BRT-LRT debate. Yes, he over stated some things and did not provide any of the benefits of LRT, but he was not trying to present anything that was balanced.
Back in the 1970s, Mr. Haydon and others did an evaluation of which technology was best suited for Ottawa and the winner was BRT. There were compelling arguments then, and most of those arguments are still valid today. I am not sure that if we were building a system from scratch today that BRT would be the winner, but it might be, and Andy certainly believes that it would be. He believes that the correct choice was made in the beginning. Unfortunately, he also believes that if everyone had seen the facts, as he did, then they would come to the same conclusion he did in the ‘70s. For him, based on his own criteria, it is a black and white issue and there shouldn’t be any debate; BRT has more benefits.
Randall Denely’s article appears to be written from a Staff document which argues why the choices they made were the best ones. He has not, from the looks of it, put any real thought into the issue either. This is unfortunate since some of the things that Staff, and Denely, are saying is highly suspect.
For example, Denley parrots the Staff claim that the average station spacing in Ottawa is 35 metres greater than Toronto and Montreal. This is directly from the Staff report
Quote:
Existing subway systems in Toronto and Montreal have stations in their downtown spaced at an average distance of approximately 500 metres. These stations typically have a single primary access point from the platform level, with multiple accesses provided to the street from a single mezzanine level. Between LeBreton and Campus, stations on the DOTT are spaced 535 metres apart; on average. While this provides a slightly wider station spacing than that found in Toronto and Montreal, it is noteworthy that each DOTT station will have at least two major accesses points from the platform level, providing increased coverage for each station compared to downtown stations found in Toronto and Montreal. Population and employment densities in downtown Toronto and Montreal are also significantly higher than those of downtown Ottawa, with greater potential for increased future development.

Now, ignore the part about Toronto and Montreal having only a single access point to the Platform but multiple accesses to the street from the mezzanines; while Ottawa will have two major accesses from the platform to the street. This ignores the new laws which require at least two access from the platform; and that Ottawa will also have a mezzanine between the platform and the street - there really is no difference here.
The point I'm trying to make is the following: I think I have posted this before, but I used Google Earth and roughly measured the centre to centre distances of stations in Ottawa, Toronto and Montreal. I used centre to centre because it removes the affect of longer or shorter platforms.
Recommended for Ottawa:
LeBreton - DT-west = 835m
DT-west - DT-east = 670m
DT-east - Rideau = 545m
Rideau - Campus = 1180m
-----------------------------------
This gives an average centre to centre distance of 807m.
For Toronto:
Union - King = 370m
King - Queen = 380m
Queen - Dundas = 455m
Union - St. Andrew = 515m
St. Andrew - Osgoode = 310m
------------------------------------
The average centre to centre distance is 406m. About half of the Ottawa spacing!
For Montreal:
Peel - McGill = 430m
McGill - Place des Arts = 500m
Place des Arts - Saint Laurent = 450m
Place d'Armes - Champ de Mars = 495m
--------------------------------------
Average centre to centre is 469m. Closer, but still almost 340m shorter than Ottawa's centre to centre spacing.
You will notice that Staff claim a DOTT average distance of 535 metres which is shorter than the shortest distance that I measured. Also they claim a distance of 500 metres for downtown stations in Toronto and Montreal, but I don’t get that either. So Staff seem to be using numbers which I don’t think can be substantiated and Randall simply takes them without verifying their veracity.
For anyone to take sides based on either of these articles would be for them to take an ignorant viewpoint. Neither of these articles present a good case for their side.
Each technology and each part of them has been developed with some compromise; none of them is perfect. There are valid arguments that can be made for and against any thing.
Fortunately there is really no need to actually evaluate which technology would be the better one since Council has already taken the arbitrary direction that the tunnel will be bored and it will contain LRT.
