Yup. Forgotten about the maps with As to Ds. It all depends on
the size of the street directories that you are having. Look for
the map scale that is specified at the top or bottom of the
map.
Just a note, all this calculation of fare stages are just merely
approximations. Fare stages DO NOT give a good indication of the
time taken to complete the whole journey but they give good
indication of the distance from point to point.
Longer distance translates to higher fuel costs and thus demand
for the service must be really there to make the service
economically viable.
For example, taking sbs 8104h 140 route suggestion from Braddell
Bus Pk to Changi Airport,
i take bus 73 as a reference from Braddell Rd B07 just besides
the SBS bus depot. It takes 1.5 fare stage to go to Lor 6 Toa Payoh
B11 outside Blk 1.
Next, I take svc 59 as a reference. It takes 3 fare stages from
Lor 6 Toa Payoh B11 to Lor 6 Toa Payoh B02A Toa Payoh Swimming
Cplx. However, 59 uses Lor 1 Toa Payoh while the suggested route
uses Lor 1 then Lor 2 then Lor 6 which is shorter than 59 by 1 bus
stop. Distance between the two bus stops is approximately 400
metres which is 0.5 fare stages.
So, it takes 2.5 fare stages.
Total fare stages from Braddell Bus Pk to Lor 6 Toa Payoh B02A
Toa Payoh Swimming Cplx is about 4 fare stages.
I measured out the ruler and calculator. about 30.18 fare stages
for sv140. rounded off u get 30.
oh and i wasnt talking about A to D. I was talking about the two
sizes mighty minds comes in, one is 1:12500, the other is 1:some
weird number. the A to D is 1:6250 for the bigger version.
