1. Services 131, 167, 186, 700 and 970 use Cecil St while the other
services use Robinson Rd. What decided that these 5 services use
Cecil St? Can't services 131, 167 and 700 be amended to use
Robinson Rd as there are more passengers there?
2. Services 7, 32, 51, 61, 63, 80, 145, 197, 851 use North Bridge
Rd while services like 2, 12, 33, 62, 130, 133, 960 use Victoria
St. Services 61, 103, 166, 197 use South Bridge Rd instead of New
Bridge Rd. Services like 147 and 190 use the entire stretch of New
Bridge Rd while services like 124, 174, 851, 961 use New Bridge Rd
only after turning from Upper Cross St.
What decided that which services use this road and which services
use the other road?
3. Service 130 use Coleman St but return via Bras Basah Rd, and use
Ophir Rd but skip Rochor Rd to use Kitchener Rd. Service 131 use
Serangoon Rd and Rangoon Rd but skip Rangoon Rd, Kitchener Rd and
Jln Besar in the other direction. Service 961 and 980 use North
Bridge Rd and Jln Sultan instead of contiuning via Crawford St and
turning right into Beach Rd. Service 980 use Bencoolen St towards
Lor 1 Geylang, but on the return trip, instead of using Selegie Rd,
it use Victoria St, Rochor Rd and Rochor Canal Rd.
Why do those service use this road but on the return trip, instead
of using the same road, have to use another road?
