Most people working in Joo Koon, live around Jurong West / East
town for convenience to work place. Hence, route planners have
tried to give as much direct connectivity to Joo Koon from these
towns as possible.
From east to west:
st 63: 192
st 64: 193, 256, 258
st 61 / 71 / 81 / 82: 258
ave 4: 99 (1st stop), 193 (next 3 stops)
ave 5: No service (1st 2 stops), 99 (next 2 stops)
st 91, 93: 99
Jurong East Town: 99
This way route planners have almost covered all of Jurong West
Town... except for few bus stops. So I think bus usage will
increase between Boon Lay and Joo Koon due to point to point
connection, and MRT use will take a hit between Boon Lay and Joo
Koon MRT.
At same time MRT will benefit with more people taking MRT from
Joo Koon than Boon Lay. It will see some easing of crowd at Boon
Lay interchange as well.
I think the proportion of people
working in Tuas who live in Jurong West may not be that great, as
there are many pax who transfer to MRT at Boon Lay to other parts
of Sg. Still, the extensive bus connections between Jurong West and
Joo Koon are needed for JW residents to x-fer other JIS (and
probably to Fairprice Hub for shopping), but not sure how much
demand there really is.
99 and 258 serve this purpose,
although as mentioned by others, 258's demand is likely to be
greater between Boon Lay & Pioneer. I don't think many pax
would take 99 all the way from Jurong East/West Ave 1 to Joo Koon
though, as 99's route is quite winding.
As for the other amendments, it
seems LTA has tried to maintain the lost links as far as possible,
including a surprise decision to extend 194, which actually makes
sense. (251 covering 254's sector along Boon Lay Way, 194 covering
251's sector along Jln Ahmad Ibrahim)
193 amended to serve Joo Koon,
skipping Upp Jurong Rd/PIE, means 1 less bus svc to Pasir Laba
Camp. Just hope 182/M can be better managed w less bunching and
higher freq, with the route shortened.
As for amending 192 to JW St 63,
I think it's to give residents there a more direct link to Joo Koon
via Upp Jurong Rd. Using 193 to cover that sector instead would
mean a longer route via Pioneer Rd Nth/ Lok Yang Way.
