190 may still have a high load, due to using Bukit Panjang Road,
without any detours. 972 might not have a very high loading due to
routing around Bukit Panjang Town, but I see the load coming from
the LRT areas: Bangkit , Fajar, Segar and Jelapang, though it does
duplicate 922 and 971E a lot. Anyway, thanks for loading up the
poster here! 
Quite a unique route. 190 loading will not be affected. If at all,
it will take away loading from sv 700 as people take bus/LRT to BPJ
and change to 700 to go to Orchard instead of 190, as 190 is
already packed when it comes to BPJ (no seat to sit)
