If you had read properly, the 55 people scenairo was a if (I suppose you don't need me to explain this word), and was done to show how inefficient double deckers are when there is a full load, the purpose is to show the flow, for a full bendy would have more choices to take when it comes to alighting.
In any bus, passengers would move in if there is a huge space left by those who have alighted, and if they don't, prompting from the drivers will encourage them to do so. On a bendy, the alighting passengers take lesser time to alight, and therefore whoever's supposed to move further in to the empty spaces are able to move in at an earlier time (lets say its time a) as compared to a double deck, and consequently, whoever's boarding can board earlier (lets say its time b) than if it was a DD.
On a double deck, because the alighting passengers who are the last to alight (usually) come from the upper deck, and that they take longer to alight, people who want to move in or upstrairs can only do so later (lets say its time c), which means people who want to board can only board later (lets say its time d)
Here a<c and b<d.
And all this is before considering the fact that people may not move upstrairs because they are alighting in a few stops.
If there weren't a lot of people alighting from the upper deck of those buses at CCK, there wouldn't be a jam and I wouldn't mention it. But there is, so I think it is still better for you to go there and see for yourself. Yes DDs may have the front doors available for alighting at interchanges, but it doesn't really speed things up by a lot, because it is still one line from the upper deck to the lower deck, and having to walk from the stairs to the front door takes a slightly longer time. And thanks for pointing out, bendies also have an extra set of doors for alighting at the interchanges.
you are basing on the fact IF there is full alighting of the 55 people on the upper deck with significant boarding activities as well...how many bus stops have such situation whereby all 55 paxes will alight at the same stop?
the example given by you at NP/Sim bus stops are out of the scenarios right now...
further based on the actual number of paxes alighting, the dwell time at bus stop wont be 100% more for DDs.. that is a fact...
and back to your "a<c and b<d.", this is technically correct, but i have also pointed that the no of DD that can stop at a bus stop compare to a bendy...so u need to take into consideration that as well (and for bus stops with no significant boarding/alighting activities), so if 3 DD pull into a bus stop and pick up /alight 5 paxes and each bus stop for 20 sec, so 15 paxes were clear from the bus stop in 20 sec.. but if 3 bendies go into the bus stop and pick up/alight 5 paxes and each bus stop for 20 sec, the last bendy will only leave the bus stop 40 sec later (thus holding up traffic on main road for 20 sec).... pls do consider this fact as well...
as for the CCK situation, you are saying that all the DD are full when arriving at CCK interchange? how can it be? tot those bendies keep saying that the DD wont have much ppl going up stair when travelling short distance? now you are painting a picture that all DDs are fully loaded at the upper deck when reaching CCK, thus causing all the delay.
Originally posted by BusAnalayzer:Coz it does not have demand that warrants DDs (yet). Ofcourse if 85 can get DDs, every service can get.
853 pass through so many areas, so dunno which MP need to come out and say something...
Originally posted by SBS7557R:Lesser feeders, precisely the point. Why are areas managed by TIBS/SMRT having so many feeders for a residential town (8 in Woodlands & 6 in Yishun), while certain areas managed by SBST that are of the similar population density as Woodlands/Yishun have only 4-5 feeder services?
For a start, more feeder mergers to form routes like sv3/38/60 should be conducted.
No.
Thats only one matter.
There is also the need to intro more point-to-point. Like 161 and 168.
This effectively removes H&S and allows for DDs, as well as bus resources, to be well used.
172 starts DD today... SMB5056S

Oh. I guess thats the one i just saw. Abt 3 mins going to reach boon lay int haha

I think might be 2,Some bus fan told me there was 2.
I think 172 demand set to rise when Tengah gets developed.
Originally posted by carbikebus:I think might be 2,Some bus fan told me there was 2.
yup. got at least 2 coz just now the one that i spotted got the red-black SMRT logo... 5056 has the red one

i will try observe the DD slots when i take 172 tomorrow during AM peak...
I am awaiting for svc 167,180,184 & 980 to get DDs.
There is at least 3 DDs on 172..

Oh wow.. I spent few hours at CCK Interchange yesterday and didn't see any DDs on 172... so has to be from today... Good job.. finally!!
985 DD arrives at CCK Interchange at 18.20 hours. Was a bit surprised, as this means it does not really do the Lor 1 - CCK route during prime peak hours but just before peak.
No sv 67 DD appears at CCK Interchange between 17.40 and 19.20 hours... First DD appears at 19.20 hours... This means all KJDEP DDs are timed for peak hour from Tampines to CCK (looks like)... OR I just missed the DDs departing CCK for peak trip between CCK and Tampines. Nevertheless I think DD timings on sv 67 seem to be timed for peak hours correctly unlike sv 985.

Problem for 67 now it is spammed with a hell lots of A22s..Might as well cut 3 SDs and put just 1 DD to perform..Reduce 2 split duties for weekdays,Most of the time during peak hours,Buses from either depots loves to follow each others which result in less loadings and bunchings..Today at Tampines around 1816hrs only 3 A22s,1 bendy and 1 DD enter int at an average of 5 mins!.969 face overcrowding issues again and i see 2-3 A22s really cant cope with the paxs around 1800-1830hrs

To prevent excessive long waiting times caused by heavy traffic at sectors nearer to int, they have to deploy more buses at one go.

There was only one DD on 172 yesterday (15/7) which was on 172S107...i spotted the whole fleet...

Yup..this timing seems to be 172S107... it will reach BL int at 1752 hrs...
Did you spot svc 172 the whole day?
Originally posted by SMB128B:To prevent excessive long waiting times caused by heavy traffic at sectors nearer to int, they have to deploy more buses at one go.
I believe this wasnt a good excuse,Meaning 3-4 SDs at one go is good rather than deploy 2 DDs?
Originally posted by carbikebus:Did you spot svc 172 the whole day?
i took 172 full route during AM peak and full route at 4 plus...none of the AP buses are DDs and 5053A ran on 172S107 on both AM and PM peak...
Lucky i never go there yesterday..The bus fan must have mistaken giving wrong info
Not surprised... coz SMRT side have no spare DDs to give... all KJ buses already deployed on perm services.. Might be able to give one bus max... or have a fleet add from BSEP side... as there are quite a few KJ BSEP DDs spare.
Also... I feel from BSEP KJ side... 3-4 DDs will remain spare until end of year when 983 gets extended to BPJ.. Looking at the loading on sv 983... for sure will need more DDs... In fact... can already make 983 full fleet DD with 4 DDs... as the demand warrants it during peak hours + more and more flats opening up in Keat Hong area.
Originally posted by carbikebus:Lucky i never go there yesterday..The bus fan must have mistaken giving wrong info
Only managed to spot all AP buses for 172 during my ride during AM off peak...all rigids... but while i was at cck int at 0815hrs, spotted the DD (unsure rego) leaving cck int for Boon Lay, and that slot was again 172S107...
Anyone who wish to take the DD on 172, i have posted the timings for this duty in another thread before :)
