6:33 - 6758E - 51pax (looking at the trend, I assume previous bus would be 6:23)
6:42 - 8698K - 46pax +09m
6:52 - 3110Y - 55paz (DD slot) +10m.
7:10 - 6790P - 58pax (the frequency of 103 drops after 7pm) + 18m
7:30 - xxxx - 59 pax (could not note the rego as I went to see 5311H on 109A) + 20m
* Frequency of 103 is at 10m, but drops sharply after 7pm. I believe this is because by then the loading at SAP dies down and those along YCK road are expected to take 43/43M/70
* Loading per bus departing NEX is quite decent at 50+ pax. I have a feeling these would be dedicated patronage along Jalan Kayu HDBs/dorms. Those alighting at YCK road would be in minority given that there is 43/43M/70 and some downroutes on 70 from NEX bus stop at better frequency.
* There should be few more people boarding at Serangoon MRT stop along Upper Serangoon Road, taking the loading to 65-70 pax on each bus.
* 103 for sure can try some more DDs.
6768E, and XXXX should be 8359P
Loading level can be quite high during weekends on service 89 (sectors between Sengkang - Blk 298A till Pasir Ris - Downtown East and vice versa during afternoon and evening) due to service 89 having a majority of SDs (KUBs and Citaros cameoing) alongside with 6858D and 6859B. There are cases where there could be high passenger load + traffic conditions with could results in buses being almost 25-30 minutes apart.
43 really needs more DDs. Full SDs are very common during pre evening peak (1.30 pm - 5 pm) throughout the route, and is particularly common from 3.30 pm onwards. SDs come at frequency of 11 min, but are still full even with 43M.
The DDs in off peak are mostly on back to back slots, and have shorter headway than SDs. Headway of bus X refers to the waiting time from previous bus to bus X.
Off peak headways of A/P DD slots:
3461: 19 mins
3506: 13 mins
3462: 13 mins
3440: 11 mins
Compare with SD:
6489 (before 3461) 18 mins
6512 (before 3506) 20 mins This slot has extreme loading and almost always full from NEX to Sengkang! 8 minutes longer headway than the subsequent DD.
3462 is directly after 3506. Both DDs often have super low loading compared to the huge no of pax who cant get onto 6512 on YCK rd. Even if the pax from the 2 DDs were merged into 1 DD, there would still be enough seats for all the pax.
The huge loading on SBS6512B slot is a one off compared to the buses before and after, but is not one off for how often it happens. Strangely enough it does not happen on Wednesdays.
Another problem on 43 is 'pax hogging', a more serious form of bus bunching.
This is how it works:
2 buses on the same bus service arrive together. The first one is SD and the second one is DD.
A crowd of pax board the SD, not noticing the DD. This allows the DD to overtake the SD. But it can also cause the SD to be full.
But if the pax all board the DD, it slows down the DD and the SD may move off first if it is late. The SD will eventually be full if there are enough pax and the cycle repeats until the buses reach the terminal.
However, bus hogging can be more serious than above scenario.
If the SD is very close in front of the DD, but not near enough for the BC or pax to see each other, the pax will all board the SD. If there are enough pax, the SD will be full and the DD will be empty.
Just go to YCK Rd or Buangkok and see how often it happens. It happens in 50% of all bunchings between 43/M.
I wonder if the SBST schedule planners have been eating snake.
Somehow, a S shift bus (usually SBS3434M or SBS3445G) departs Punggol at 6.32 am, but uses off-peak run time. This bus is almost always late.
(Oops, SBS3440U is now on A/P slot.)
This is regular scenario on sv 43 I agree. Many times 43 and 43M DD will come together and one of them will go empty all the way back to Punggol. Hence, my suggestion to make 43M full fleet SD and transfer the DDs to 43 instead. LTA/SBST is pretty slow to react. They are okay actually wasting plentiful resources. Just like 119 now for 3.5 years operating with empty DDs.
Dont worry,GA will make 43 18 DDs and 2 SDs while 43M will be 4 SDs and 2 DDs.136 will have perm 2-3 DDs during Weekdays.518 will add one more DD and will ply KPE.Svc 2 will be full DDs and svc 12 will have an adjustment of 2 SDs to 2 DDs conversion.

I was hoping for 23 buses for 43 with 20 DD, 3 SD.

Hi mr carbikebus, now quite slow already. Hope the new operator does not introduce new things to make it slower on accounts like spreading out the buses. Cheers. Thanks.

Is this your assumption or insider news?

Bro... first let us have some incremental improvement before expecting too much.. what cbb is suggesting is already a great improvement over what we have today.

legit one
Dont expect too much be it buses or what,Later crawl like mad you yourself will say why so many buses..

Hi mr carbikebus, yes agree. This bus contracting model is just a disguise. Colour change only. Nothing interesting. Just use back most of the SBS transit buses with the sbs logo being struck off only and a bus driver in another uniform. Hope the go ahead group does not bring crawling speeds to the services in pasir ris Punggol area. Currently, travelling times from this part of island to other areas by buses are quite lousy already. So don't add on to our misery. Cheers. Thanks.

Isnt it LTA who plan the schedule and runtime?

We just hope and see,New bus companies cant do anything.LTA guys will just follow to take and adjust accordingly to their survey.Hope you understand.

Hi mr smb3163D, yes. I hope they do not OVERDO it for the area which I live. Welcome Go ahead group Singapore this Q3 2016. Cheers. Thanks.
SBS3459S on 43 Duty 11A (SBS3461J) today.
BC was late by 5 min on first trip. Depart Punggol at 6.40 am, entered YCK Rd at 7.11 am (scheduled 7.06 am)
Bus was packed to the door by the time it reached Buangkok MRT. But not without 20+ empty seats on upper deck.
Originally posted by carbikebus:Dont worry,GA will make 43 18 DDs and 2 SDs while 43M will be 4 SDs and 2 DDs.
No SDs can depart Punggol at 6.25 am to 6.45 am. And frequency must be at least 8 mins for 43. No planned bunchings between 43/43M.
Even DDs often get packed to the door during this time period.

Even if you planned,There will still be hiccups..Nothing is perfect.
If u went thru in NS in the army, mission planning can be sui sui, Force prep also tip top when come to executions, All kinds of shits happens haha
Express bus service 502
Observed the loading on this bus service today from 5:39pm to 7:28pm, from Orchard Road to Pioneer Road North.
In the city, I only observed the number of people boarding the bus as I only wanted to find out roughly how many people take bus 502 back to Jurong.
The number of people boarding the bus is as follows,
Orchard Road: +39
Bras Basah Road: +15
Temasek Boulevard: +7
Temasek Avenue: +5
Bayfront Avenue: +2
Central Boulevard: +14
Shenton Way: +20
When the bus ran express from Shenton Way to Boon Lay Way, there were 80 people on the bus - 52 at upper deck, 28 at lower deck.
When the bus was in Jurong, the following loading was observed:
Boon Lay Way: +4 -4 (80 pax)
Toh Guan Road: +12 -24 (68 pax)
Jurong East Avenue 1: +8 -31 (45 pax)
Jurong West Avenue 1: +11 -20 (36 pax)
Boon Lay Avenue: +4 -11 (29 pax)
Jurong West Central 1: +0 -1 (28 pax)
Jurong West Street 64: +0 -9 (19 pax)
Jurong West Street 75: +1 -11 (9 pax)
Jurong West Avenue 5: +0 -7 (2 pax)
Pioneer Road North: +0 -2 (0 pax)
Soon Lee Road: No data (but very likely is +0 -0; 0 pax)
190 and 972 continue to have extremely high loading during peak hours. 700 has lost its loading completely. 960 still has decent loading during peak hours from city to BPJ and Mandai to Woodlands but opposite direction loading is miserably low.
Thursday evening observation of frequencies at Whitley Road bus stop
Timing: 18.10 - 19.20 hours
190 - consistently arriving between 03-04 mins per bus. On average buses had around 60-80 pax.
972 - frequency quite abrupt between 04-12 mins per bus. Quite a bit of bunching. On average buses had around 60-80 pax.
960 - frequency is around 07 mins interval when A22, and around 14-16 mins when E500 or bendy. On average A22s had around 50-60 pax and DDs/bendies had around 60-70 pax. Not so bad still but observed opposite direction most buses had <20 pax. Also note frequency has reduced. Is 960 still operating with 30-32 buses? I doubt so.
700 - frequency around 10-16 mins. Buses had seated loading around 40-50 pax per bus.
