Ok I'll repeat myself until it sinks in. THERE IS NO NEED FOR A DRL NORTH OF BLOOR WHEN SMARTTRACK IS BEING IMPLEMENTED.
If we bring the Relief Line to just Pape, then the Yonge Subway in 2031 will be as crowded (read: overcrowded) as today.
Neither SmartTrack (equivalent to RER+ on above graph) or the "Relief Line U" will relieve the Yonge subway as well as the "Relief Line LONG" to Sheppard.
The LONG option intercepts busy bus routes along Sheppard, York Mills/Ellesmere, Lawrence, as well as the Eglinton Crosstown when complete. According to the TTC 2014 Surface Route report, the daily ridership for these lines are as follows (in above order): 29,000, 27,500, 33,700, 28,100, or 118,300 total. (And this is not even including other routes like the 100 Flemingdon, 51 Leslie, 56 Leaside, and 25 Don Mills (38,000 on that route) that also operate east of Yonge. )
Bringing the Relief Line up to Sheppard is critical. More so than any other transit project after the Relief Line to Pape Station.
