Running more artics and increasing service on the core routes should help quite a lot. When the proposed service hours for 2024 can actually happen, here's what should be the priority at minimum:
501: 5 mins all day combined, including bringing back 501A, 12-15 mins on both Saturday/Sunday combined. Also start some trips at The Gore Rd
502: Make a branch that short turns at Shoppers World so reliability can be improved
505: 7 mins peak, 10-12 mins at all other times combined with 505A, run artics at all times like the other Zum routes, and extend hours to at least 10PM
511: If possible make a branch going from Bramalea-Sheridan College until 504 goes into service
3: 10 mins peak, and 20 mins off peak
4/104: Make 104 an all day thing running at least 12-15 mins, and give more artics to 4/4A
5: 10 mins peak, 15 mins off peak combined
7: Run more artics
14: 5 mins all day as its now desperately needed, and run more artics
15: 8-10 mins peak, and 12-15 mins off peak combined
18: Run artics at a few select times
23: 20 mins off peak/weekends, 12-15 mins peak
29: 10 mins peak, and 15-20 mins off peak, and artics at a few select times
30: 8-10 mins peak, and 15 mins off peak/weekends
50: 8 mins peak, 15 mins off peak, and run some artics at a few select times
