What I'm thinking is that,
(This for Singapore to Johor)
After going through immigration at Woodlands checkpoint, merege the
queues for SMRT and SBS Transit and join the bus queue into a
single line(or two lines) for more efficient bus frequencies and
more people therefore can be transferred over to Johor
Checkpoint.
Causeway Link can also be added in, but SMRT and SBS Transit are
two main choices since they are using the same fare payment
method.
And because 160,170X and 950 terminate at Kotraya II Ter, after
going through Johor checkpoint, their queues can be merged for
faster bus frequencies, although it is highely unlikely that most
of the passengers will take those buses. 170 terminates at
LarkinTer.
(This for Johor to Singapore)
The same story really, after going through Johor Checkpoint,
merge the queues, BUT after woodlands checkpoint, the berths remain
since they split their destinations from thereon.
Good Idea or Bad idea? I don't really see that much cons in this
but more pros. People might ask if you get charged more for
changing buses(SBS and SMRT only), I can say that from what I know,
you're not going to get charged more.
