In a previous article, I discussed the Eglinton-Crosstown LRT subway and the issues raised by demand projections for it. On July 26, I met with staff from Metrolinx to explore the subject in detail, and this post summarizes our discussion.
What Network and Land Use Drove the Demand Model?
Before we can understand the numbers generated from any model, it is important to know the assumptions behind it. Is the network a realistic view of services that will actually be in place? What residential and work locations and densities are used to generate the travel demand flowing through the model?
Notable by their absence from the map of passenger flows are any extension of the Sheppard subway, the proposed Richmond Hill extension of the Yonge subway and any reference to GO Transit routes or demand.
Metrolinx replied that their model includes only those routes and services for which funding is committed. This means that only the Spadina Extension, the Eglinton line, and the GO improvements in GO’s 2020 plan are part of the model. In effect, this takes the transportation network to roughly a 2020 state.
However, the underlying land use represents 2031 population and job projections with growth concentrated in major nodes such as Yonge-Eglinton and Scarborough Town Centre. Continue reading
