One objective of having Joo Koon Bus Interchange is to reduce
duplication of resources.
The new length and the new estimated travel time is now
available for all affected bus services. So, it's time to
compare.
Before Joo Koon Bus Interchange opened, the
original total length of the ten affected bus
services (99, 182, 182M, 192, 193, 194, 251, 254, 255, 257) is
251.2
km and the original total
estimated travel time is 848 min.

after all, one objective of Joo Koon Bus
Interchange is to reduce duplication and save resources.
New 99 (Joo Koon) length is 16.9 km and estimated travel time is
85 mins.
New 99 (Clementi) length is 16.5 km and estimated travel time is
83 mins.
New 182 length is 30.2 km and estimated travel time is 76
mins.
New 182M length is 29.4 km and estimated travel time is 71
mins.
New 192 (Tuas) length is 11.7 km and estimated travel time is 47
mins.
New 192 (Boon Lay) length is 11.4 km and estimated travel time
is 46 mins.
New 193 (Tuas) length is 15.7 km and estimated travel time is 55
mins.
New 193 (Boon Lay) length is 16.2 km and 57 mins.
New 194 length is 9 km and estimated travel time is 39 mins.
New 251 length is 13 km and estimated travel time is 43
mins.
New 253 length is 10.9 km and estimated travel time is 44
mins.
New 254 length is 17.8 km and estimated travel time is 56
mins.
New 255 length is 8.8 km and estimated travel time is 31
mins.
New 256 length is 12 km and estimated travel time is 40
mins.
New 257 length is 14.6 km and estimated travel time is 49
mins.
New 258 length is 14 km and estimated travel time is 60
mins.
I calculated two times. First using calculator and using the
values written here. Second using excel and retrieving the values
again from Transitlink website. On both calculations, I derived the
same values.
Total new length is 248.1 km.
Total new estimated travel time is 882 mins.
Total length is shorter by 3.1 km (251.2km original - 248.1km
new).
Total estimated travel time is longer by 34 mins (882mins new -
848mins original).
Conclusion:
Yes, there is less duplication of resources.
No, there is no savings in resources. In fact, more resources
are used.
