I know but it will not work because 173 route is quite unique
and if you take that away there is no alternative
connection.
Chestnut - Bukit Batok is not important, but Chestnut - Hillview
is... and Hillview - Bukit Batok is because you have only 173 and
176. 177 is only during peak hours.
Thinking about it, there was another reason why I chose to split
173, and that was to link the Hume (and Chestnut) estates with
Hillview MRT and Bt Panjang. This link would be utilised better
than the current one from Hume to Bt Batok. (I wouldn't want to
touch the longer trunks, i.e. 75, 171, 184, 961, just for these
short sectors.)
Considering the demand for Hume and Chestnut is generally low,
while that for BB East Ave 4, Hillview Ave and Yew Tee is
moderately high, it makes sense to operate the services separately
for these two sections, with different bus intervals.
Thus we have:
