Technical Call

• Update from Jeff Doyle on transit virtual path building performance
• Here's some settings and results for discussion

Time to execute run_sub_simulations step mp_tvpb : 670.767 seconds (11.2 minutes)
Time to execute run_sub_simulations step mp_mode_choice : 327.657 seconds (5.5 minutes)
Time to execute all models : 1333.193 seconds (22.2 minutes)

• Note previous single threaded on-demand / redo calculations runtime was 3 hours
• There isn't a comparable runtime for a 775k work tours mode choice from Marin TM2
• Results the same as before
• Now working on verification summaries and user documentation
