LRT, BRT, streetcars, and buses are not just cheaper transit alternatives to subway systems. They provide various levels of service that are optimal for differing circumstances. Surface transit can and regularly do match a subway system for capacity or speed. More vehicles are required and take up more space; less stops are required and provide lower service levels; nevertheless, they can do the job they are intended for when not touted as cost-slaying champions or lampooned as service-slashing shortcuts.
Building subways, like building roads, is not a mystical ‘key’ to gridlock and only serves to increase congestion by supplying suppressed demand. Toronto’s population annually grows by the size of Kitchener. Over the next 10 years, the GTA’s growth will exceed the total size of Calgary, Edmonton, or Ottawa. A more extensive subway network will partly address this growing demand, but we should not be under any illusions that multi-billion dollar investments will do more than at best maintain the status quo.
Metrolinx is tasked by
MoveOntario 2020 with 54 major transportation projects in the GTHA with a primary $17.5 billion funding. Metrolinx's goal is to build strategic network links now to enable a much higher system integration over the next 20-30 years. Trying to divert this sliver of funding to underdeveloped schemes will not work.
Finally, London's Congestion Zone Charge has an net operating income of 35.3% and is one of the most efficient in the world. At a flat fee of $5 and assuming 1,000,000 trips a year with this efficiency, it would take 38 years to pay for just the 33-km Eglinton line or 66 years for the system at her assumed $200m per kilometre.
Transportation, like all parts of the economy, is integrated and any change to any part of the system will have impacts on every other part in the system. Make highway travel less desirable and more people will take transit and local roads. Make the TTC user-fee free and businesses will still depend on truck deliveries.
