With Trevor Horzelenberg- on Modeling Impacts of LRT on Traffic

The following is a Q/A we had with Trevor Horzelenberg,  Manager, Light Rail Transit. Our questions concern  traffic modeling software that is being employed to predict the impacts of LRT on traffic flow/congestion. Here is our Q/A:

In an article in The Hamiltonian Spectator, you stated that the traffic modeling related to LRT is at a preliminary and high level stage and that it will become more informed as time passes and variables are injected. That being the case, in its current state, how reliable would you estimate it is?

Can you provide a copy of the modeling report that your comments were based on.


We are updating Council now on the approach we’re taking to project any traffic impacts that could be associated with implementing LRT. This is a preliminary report and more detailed information will be presented to Council when the ongoing studies are complete. All of the information referenced in the preliminary report is reliable.

When the studies are complete we will be working closely with City of Hamilton Traffic staff to develop solutions for any traffic issues that are identified. For example, there may be opportunities to change signal timing, restrict turning movements or add dedicated left turn lanes at some intersections.

The report can be found at the link below. It is agenda item 7.2.

Should you have any further questions and/or concerns, please feel free to contact me.

Thanks Trevor for the information.

  1. Q: Would BRT modelling incur significantly different impacts?

    1. Maybe during construction but not once it's built out. BRT uses dedicated lanes just as LRT does. Operating speeds are slower than LRT, so one can imagine that signal priority would mean a slightly longer lag time at signalized intersections.

  2. I have noticed that when lanes are blocked or restricted-particularly on busy streets- congestion increases. Just a casual observation, purely subjective, nothing scientific. I am not a doctor.

  3. "I have noticed that when lanes are blocked or restricted-particularly on busy streets- congestion increases." yes, especially when it unplanned, unannounced road work. or if the road work is being made available to the public, the city isnt doing a good job of communicating. now for the lrt this another non issue, and for the anti lrt crowd another red herring. the lrt build and schedule will take no one by surprise, and the can change their habits accordingly. easy peasy. follow the posted work schedule, avoid those stretches under construction and go on your merry way. well, way. of course, for a certain amount of people, no amount of advance warning of road work will help cause some people will never get the message cause of whatever and they will always be taken by surprise by even the most rigorous of warnings. and of course, members of "the great silent majority", who will not change their habits and intentionally mire themselves in traffic to say "i told you so".

  4. This 2021 model also identified the most significant impacts were due to the reduction of capacity of King Street West which resulted in additional volumes on York Boulevard and Dundurn Street.

    In summary, the previous design and traffic modeling done in 2010/2011 identified that the implementation of LRT could be accommodated by the existing network, albeit with a general reduction in performance for other road users on certain corridors, and the introduction of some intersection and other corridor improvements to mitigate the impact.

    Guess Whitehead is right about people spending more time on the road away from their families.

  5. Provincial legislation may also be one of the variables impacting traffic modeling. The following passages are taken from policy section 3.2, Policies for Infrastructure to Support Growth, from Proposed Growth Plan for the Greater Golden Horseshoe, 2016:


    Transit is the first priority for transportation planning and investment. The transit network will support and facilitate improved linkages between strategic growth areas and other areas planned for a mix of uses and transit-supportive densities. System users will benefit from improved linkages between and within municipalities as well as transit service integration.

    A comprehensive and continuous active transportation network will offer a viable alternative to the private automobile for personal travel. Using a complete streets approach to roadway design will ensure that the needs and safety of all road users are considered when planning and building the street network.

    3.2.2.3.
    In the design, refurbishment or reconstruction of the existing and planned street network, a complete streets approach will be adopted that ensures the needs and safety of all road users, including pedestrians, cyclists, transit-users and operators, and drivers of cars and trucks are considered and appropriately accommodated.

    3.2.2.4
    Municipalities will develop and implement transportation demand management policies in official plans or other planning documents or programs to: a) reduce trip distance and time; b) increase the modal share of alternatives to the automobile, which may include setting modal share targets; c) prioritize active transportation, transit and goods movement over single-occupant automobiles; and d) target significant trip generators.

    3.2.3.1
    Public transit will be the first priority for transportation infrastructure planning and major transportation investments.

    3.2.3.4
    Municipalities will ensure that active transportation networks are comprehensive and integrated into transportation planning to provide: a) safe, comfortable travel for pedestrians, bicyclists and other users of active transportation; and b) continuous linkages between strategic growth areas, adjacent neighbourhoods, key trip generators, and transit stations, including dedicated lane space for bicyclists on the major street network, where feasible, or other safe and convenient alternatives.

  6. those who use the system the most matter the least. Knowing we would never agree collectively to such a plan, the decision has been made on our behalf. Democracy in action.
    This sort of respectful engagement is intended to inspire motorists to leave the cars at home, hop aboard the HSR, and consider the traffic circle as a unique family destination.
    Fear not, this has all been planned very carefully.

  7. "those who use the system the most matter the least" that is the current state of the hsr. transit riders use the system, pay for it and get poor service and outdated tech. the coming of the new lrt will be the first step in addressing these current deficiencies. whether or not road warriors and car enthusiasts change their behaviour significantly will be seen. one thing for certain, the cars will be sharing the roads with the lrt AND bike lanes AND two way conversions AND new pedestrian right of ways at crosswalks AND other traffic calming tactics. of course every expert says the lrt will have a minimal impact on traffic. no expert has said otherwise. but jim and others keep saying traffic chaos is coming. just like they said (wrongly0 traffic chaos would ensue when every time we converted a one way to two way.

  8. while at least one anonymous scholar continues to struggle with elementary mathematics, another elected genius wants to add "reversible lanes" to the discussion on Main Street. It is reassuring to bear witness as the depths of this carefully planned process unfold, truly inspirational.

  9. "another elected genius wants to add "reversible lanes" to the discussion on Main Street" why would we automatically dismiss the idea of reversible lanes on our streets? works quite well in other cities.

    1. why would we introduce it after 8 years of careful planning? after paying consultants to examine the impact of LRT on the current design?
      It works quite well in this City,- because it addressed a need, and was properly designed.

      Delete
    2. building lrt on the ling corridor doesnt preclude us from using reversible lanes elsewhere in the system. oh yea jim graham and terry whitehead want a complete and total moratorium on any and all changes to any lower city street till lrt is completed. good plan guys.

    3. Sorry but it really doesn't work well here where we have it on the Sherman cut.

  10. "Getting excited for the big day" me too. "how many more sleeps?" too many. but theres still plenty of to be done. fully protected cycling right of ways up and down the claremont, expansion of the cycling lanes, upgrading all cycling lanes with car barriers, getting all residential streets in hamilton 30 k p/hr, adding more traffic calming measures like speed bumps and red light cameras, getting municipal parking rates increased downtown, getting all illegal and non conforming parking lots closed down, changing municipal tax laws and zoning laws to make parking lot operators pay their fair share, more renting of parking spots to vendors and business for instant curb presence, more pedestrian controlled crosswalks and right of ways, better and safer sidewalks. so even though lrt is a ways off jim, we will be busy transforming this city beyond your most vivid nightmares. oh almost forgot, the big project, total ban on cars through downtown wellington to queen. bam. hows that sound jim? we have accomplished sooo much in the way of walkablity, traffic calming, public transit, subsidies for cycling, the list is long and growing. what victories do you and your co horts claim? just keep paying your tax's on time. we need a lot of money for our future endevours.

    1. miraculously, under your watch, fatalities between pedestrians/cyclists and motorists have skyrocketed. Coincidence? Your idea for an all out ban is brilliant, you really need to step up and receive the attention your efforts deserve. Your needs have never really been in doubt, just your ability. Mockorangemike.

    2. "miraculously, under your watch, fatalities between pedestrians/cyclists and motorists have skyrocketed" usually the fault of the driver. dont let this fact get in your way. im sure once we are all driving jim graham approved electric flying cars of the future people can cycle and walk. till then, off the roads and sidewalks, jim grahams coming through.

    3. when pedestrians get in the way, they get injured, or worse,and still you clamor for more, imagine what a billion dollars spent wisely could do to improve pedestrian and cyclist safety. A vision the whole City already supports, with plenty left over for real priorities. But that would take courage, and courage is not your strong suit. Your advocacy is ineffective, your contribution is irrelevant, but your more fun than a barrel of whiskey. Carry on.

    4. jim thinks people are dumb so he says things like "cycling and walking kill people as part of the natural order of the universe so any increase in cycling and walking is a kin to suicide and promoting cycling and walking is counsel to commit murder"

    5. "imagine what a billion dollars spent wisely could do to improve pedestrian and cyclist safety. A vision the whole City already supports" are you saying hamilton could spend 1 billion dollars on cycling and walkability improvements and it would be "A vision the whole City already supports" yea right. we spent a few 100,000$ on bike lanes and a small but vocal minority got very upset and agitated and sobbed all over town. hasnt mr jim graham himself called cycling investments a waste of money over and over? this is where he tells us he cycles regularly, and has for years been an advocate of tax dollars spent on cycling infra. just like allll the bus rides jim takes on the hsr.

    6. "Your advocacy is ineffective, your contribution is irrelevant" you are actually kind of right on both counts. alone, and by itself, my advocacy would be ineffective. but together with hundreds of like minded socially conscious people that advocated together, we got, many many other things, the lrt. youre welcome. and yes, my contribution is irrelevant in the greater scheme of things, but added to the contribution of many many many other people that worked much much smarter and harder than me, many many great things have been accomplished. lrt for example. and the dozen or so i already listed. again jim, thanks for paying your tax's on time, we couldnt have done it without your money.

    7. why is it that none of these socially conscious friends of yours ever show any public support for your advocacy. I mean there are lots who share a similar perspective, but I have never-ever-witnessed anyone demonstrating support for you. Not here. Certainly not at the Spec. Why even the crew at RTH distance themselves from you like you have the plague. Why is that?

    8. "why is it that none of these socially conscious friends of yours ever show any public support for your advocacy" youre comment is nonsensical from jump street. when i comment here i am not practicing advocacy. that is not the purpose of me posting here. i enjoy posting here and elsewhere and it has nothing to do with advancing the cause or whatever. the facts on lrt are in, people should have made their minds up loooong ago.

    9. "I mean there are lots who share a similar perspective, but I have never-ever-witnessed anyone demonstrating support for you." what is "support"? true, no one has said "lay off this person" or "you go girl" in solidarity with me. you seem to think this important. im not sure what type of "support" or "backup" i should be getting. what type do you get? i see you post anti lrt comments here all the time that no one responds or replies too. are saying that you cant find articles here where pro lrt comments i made had other pro lrt people adding their pro lrt two cents? you havent looked very hard.

    10. the difference of course is you are the only one who claims to have spent the last decade or so sitting elbow to elbow with your fellow "warriors' scheming to reduce the influence of the evil automobile. Despite the effort-or more likely because of it-you have failed to generate any apparent respect or admiration. I am saying that I have not ever-anywhere-witnessed anything approaching support for your perspective from anyone. Ever.
      You generated a list of "recognizable" names a while back of locals in support of LRT. One name jumped out from the rest, she is good friends with my wife (and definitely pro-LRT. I respect her.)When we had dinner at their home recently, I asked about you. She shuddered at the mention of your moniker. After revealing your true identity, she quickly begged me not to reveal hers publicly.Fear. Your influence is universal (and appears consistent) A square peg in a round hole. Nice work.
      You repeatedly reference "we", as if you have support or backup, yet the silence belies the reality of the situation, you are alone.
      So you go girl, I will continue to mockorangemike

  11. coming from one whose only remedy for the high speed high density arterial's that bedevil him is to place more cyclists and pedestrians in harms way rendered your support for this initiative as inevitable. Knew we could count on you, full mark for consistency.

  12. "high speed high density arterial's" once were done there wont be many high speed arterials. death by a thousand cuts for high speed arterials. speed reductions, two way conversions, protected cycling lanes, and presto chango, a 59 kmph arterial is turned into a 40 knmph residential street. your tax dollars at work. thanks you.

  13. oh well then. who cares that traffic experts say if used properly in certain circumstances reversible lanes can help solve any number of traffic problems. but if allan taylor says otherwise we should just put it on the ever expanding list of potential solutions we should disregard with no further discussion or analysis cause allan taylor says so. along with jim graham that says any change to king street will result in traffic hell even though all traffic experts say otherwise.

  14. "I have never-ever-witnessed anyone demonstrating support for you. Not here. Certainly not at the Spec." really? cause right now at the spec i have numerous comments with thumbs up. not important to me, cause anyone can click and click and click to get any result they wish. i have a comment right now at the spec with 23 thumbs up and 289 thumbs down. the most number of thumbs anything on all the other comments is 35. where did the other 220 thumbs down from? 220 individual page visits where 220 people decided to give me a thumbs down and not give a thumb to any other comment in the article? or did one or more people hit thumbs down over and over? these are the type of people and their practices that you believe proves your views have broad public support and mine dont? just cause i dont have a crew like you do where allan taylor and socre say "you go jim" and "oh snap" to my every comment and you think im alone? ok then.

  15. "not important to me" so I will check in compulsively every few minutes to witness the response, and comment again just to verify the fact."not important to me" so I will whine to the editor when "they" begin to pick on me. "not important to me" so I will reference only it in rebuttal to your accusations.
    How about a comment from a real person showing appreciation or admiration for your decade of committed service? Not here, not there, not ever.
    And that was my point. You speak for no one other than you. Alone.

  16. ""not important to me" so I will check in compulsively every few minutes to witness the response, and comment again just to verify the fact." a distinction you miss or cant appreciate. i enjoy going back and forth on the internet. i enjoy posting comments if any one individual repsonds or posts something i dont like, its important to me that "i win" so i comment back and forth and back and forth and so on. childish? yes. productive? no. but i expect, need or want "backup" or "shout outs" or any "help". i have had more than one person i respect call me out and say "every minute you spend wasting your time on the internet going back and forth is time you could be doing something useful" so true. but i work hard and im not hurting anybody that counts. we all get jollies how we get them, this takes minutes a day, and its a great stress release. i have a family and a community. i dont need a cheer squad on the web to feel complete. it seems important to you though. where youre high fives from the anti lrt mob?
