Considering traffic I feel MAS-SBC Intercity is safe over 22618.
By bus via Malleswaram it takes app. 1hr 15 mins,via Mekari circle 45min-1hr
Above time frame is for direct buses towards pf #1 and pf #6(252A/258 etc) add 10 mins extra to cross highway and enter YPR
By auto it takes 35mins-50mins depending on traffic.
