This is especially true after the service has been VLS-ed. I do not
see this occurence on other buses. So it leads me to conclude that
this opening of exit doors is something gotta do with the VLS
system? But why only 962?
And I'm getting irritated with the VLS on this service. When the
buses already stop at the bus stops to alight pax, the VLS still
have not updated the fare stage and still display the 'No Tapping"
sign and thus, I juz have to get off the bus without tapping my
ez-link. Wonder how the adult ez-link users are feeling. Luckily i
use BCP. Have tried complaining to SMRT but situation is da same...

the doors of the buses have to be opened and closed at saw-tooth
berths as drivers usually start their trips on their IDFC at the
parking berth. however, by the time they travel to the saw-tooth
berth, the odometer has run and the VLS systems thinks it is
somewhere out of the interchange (STAGE 1.0) already when it is
not. the important point to note here is that everytime the
doors of the bus are opened, the VLS will call the GPS module to
refresh the location of the bus (and it will return that
it is at the interchange) and VLS will reset the fare stage to 1.0.
all SMRT SCs are notified about tis door-open-and-close command as
tis was stated as a standard procedure in every circular to SMRTB
SC's whenever there is a new VLS phase, ever since VLS started on
1st August 2004.
note that asking drivers to start a trip on the IDFC at the
saw-tooth berth is not feasible as it takes a while for the IDFC as
it has to do a lot of things before it can start a trip like
confirm the correct driver logged in, the departure timing is
correct, download other info updates like new "blacklisted cards"
list. all these is done by communicating with the starter office at
the interchange via WLAN.
also, an alternative to assign the parking berth a fare stage of
0.0 or 0.5 is not implemented.
regarding ur 2nd complaint, LTA has since modified the VLS system
to enable the BEXPs 100m prior to reaching the bus stop. however,
it is likely some buses (probably those mentioned on 962) have not
yet to update their flashware and hence do not run these
instructions. they will eventually update theirs when VLS is
enabled for that service.
but you may be puzzled by why 962 buses have not updated their
flashware since VLS was enabled on 29th August 2004. actually, i
reckon tis is an oversight.
962 buses were chosen to pilot the VLS trial for SMRT. thus, it is
likely they did not re-update their flashware and continued to use
the older IDFC/VLS versions used during the trials, whose
instructions were to enable the BEXPs only when the doors are
opened. then, the only problematic issue i heard about is that the
door sensors on bendies (which has 3 doors) require additional
programming to work. but tat was in the early stages of the trial.
i suppose with 962, SMRT is doing wat u call "if it ain't broke,
don't fix it" since the VLS version they are using is still a
working version.
however, the door-open-and-close thing will be part and parcel of a
SC's daily job, and especially more so with bendies which seem to
have more problems using VLS.
