All,
Realized we do not have a thread/topic to discuss and document
(1) traveling time between destinations
(2) round trip time for a bus service (example: sv 87 run time in one direction is 60 mins)
(3) Frequency of bus services
To start with:
sv 87 takes 45 mins between Bedok Interchange and Hougang Interchange.
Full journey takes approx. 60 mins to complete.
Total run time on sv 87: 120 mins (not counting layover time at Bedok & Sengkang Interchange)
Run time can be drastically different during peak hours and off-peak hours... Can even differ by 5-10 minutes during the same period of time just because of traffic lights.

thank you to start thread on freq.
i repost here.
freq on bus 291 = 03 min
293 = 03 min
222 = 04-05 min
225G = 03-04 min
225W = 05 min
354 = 08-09 min
358 = 08 min
359 = 06-07 min
is feeder freq so good in other town also apart bdk/tamp?
103: 55-70
Frequency for Mountbatten services:
196 has peak frequency of 05 mins from Bedok Interchange between 07.15-08.15am, after which frequency drops to 10 mins.
14 has peak frequency at 10 mins from Bedok Interchange from 07-08am, after which frequency drops to 15 mins.

Hi mr busanalyser, frequency for sbs 14 is it as follows. 6.30-8.30am -10-13 min. Quite accurate to your 10 mins. But from 8.31am to 4.59pm, it is 7-16 min. So I put it as average 11.5min. Not 15 min as what you state. Frequency is certainly not that bad until 15 mins. Cheers. Thanks.
Well, you can just check the timetables from SBST website.
P.S. 14 gets better loading on weekends (and hence better frequency with 14A).

Hi mr array88, I checked it from SBST. That is why I find huge discrepancies between posts by others and the site. So as a point to all users, please also take note to check the companies site or app before basing on your trips or observances which may not be that accurate. Cheers. Thank.
I feel the frequencies reported on company websites are NOT accurate. This is from personal experience. Sv 14 for instance I am confident of how the frequency works. During school timing in afternoon, there is time slot when 2-3 buses are departed at 7-8 min interval, but rest of the time, frequency off-peak remains at 15-18 mins.
Also company website usually have not taken into account the traffic condition. The frequency is based on regular travel time, and many times traffic/road conditions change and it does not get reflected immediately.

Hi mr busanalyser, you cannot say that you are more accurate than the company sites/apps. Many people all over singapore are looking at the frequencies. Have they been wrong, they will have been lambasted badly by the general public. They are divided into 4 different timing zones. 6.30-8.30am, 8.31am-4.59pm, 5-7pm, after 7pm. Cheers. Thanks.

I am sorry if you don't agree. It is everyone's personal observation here. I also feel you do not understand how frequency works. Let me explain you.
sv 87 has 05 min departure frequency from Bedok Interchange between 5.15 - 5.50pm, after which frequency drops to 10 mins. This means if you observe at HCI at 5.15 the frequency will not be 05 mins but will be at 10 mins. Likewise at Kaki Bukit the frequency at 6pm will be 05 mins but at 6.30pm will already start becoming 10 mins.
Hence, this is just to reflect our personal observations of services tracked on regular basis.

Hi mr busanalyser, your sort of frequency is quite subjective type. So you should indicate service frequency at certain timings in your subject in this thread. This is to prevent people from mistaking that it is the actual frequency of a particular bus service. For me, I rather trust the bus companies frequencies. Cheers. Thanks.
With the kind of Sg road users attitude and traffic condition,Buses cant 100% adhere to the frequencies,Maybe around the figures is good enough.If peak hours average is around 5-8 mins just expect it came around 7-10 mins..Dont hope for much.
Ridiculous..
979 Weekday OFF-PEAK runtime: 68mins
979 Weekday PEAK runtime: 78mins
The entire trip only takes 48 mins..

If the entire trip takes 48 mins, then what is 78 mins? Does it include the layover at Bukit Panjang Terminal?

The 4 time zones are for general services and may not be that applicable for some specific services. For example, those services passing by educational institutions (whether it is primary/secondary schools/JC, or poly / ITE / universities) usually have a different peak hour compared to most services, as students travel at different timings compared to working crowds. Thus some services maintain high frequency until 9am or even 10am. In this case, the general "8.31am-4.59pm" do not accurately reflect its frequency during off-peak hours. (Same case for PM, just look at let's say 158A)
Moreover, what I was suggesting above was to check the timetables (arrival/departure times) for specific services - you need to go to SBST website, click on route details, and click on specific bus stops to check their timetables. Not the 4-column table with these 4 categories only.

Nope, it doesn't. This is one of the few reasons why some BCs are very very early for their own schedule..

dupdup my friend not all freq state on website true. i observe my own town tamp. freq of serv 8 very high from 5-6pm cater temasek student to tamp av 2/7. same 291/293 freq better than state website in peak.
how freq of feeder 382 and 386 in punggol?

Although it may be subjective, there are specific timetables on SBST website that agrees with his point. Check out the timetables for specific routes and bus stops (not the 4-column ones) for more info.
Let's use svc 14 as an example. You checked SBST website (the 4-column table) and concluded that its frequency from 0831 to 1659 is 7-16 mins, and happily calculated its average frequency to be 11.5 mins.
But when you open up its timetable from Bedok Int, you will see: (Excerpt)
| 06:41 WAB | 06:51 WAB | 07:01 WAB | 07:11 | 07:21 WAB | 07:31 WAB | 07:44 WAB |
| 07:57 WAB | 08:09 | 08:21 WAB | 08:33 | 08:45 WAB | 08:57 | 09:09 WAB |
| 09:21 | 09:33 WAB | 09:48 WAB | 10:04 WAB | 10:19 WAB | 10:35 | 10:47 WAB |
| 10:59 WAB | 11:11 WAB | 11:23 WAB | 11:35 WAB | 11:47 WAB | 11:59 WAB | 12:11 WAB |
Which means, from 0641 to 0731, its frequency is quite consistant at 10 mins. After that from 0731 to 0933 frequency drops to 12-13 mins. But after 0933, frequency is as bad as 15-16 mins... Not the 11.5 mins based on your calculation.
The reason why it's stated as "7-16 mins" is because: (Excerpt)
| 14:01 | 14:13 WAB | 14:24 | 14:35 WAB | 14:46 WAB | 14:53 WAB | 15:00 WAB |
| 15:07 WAB | 15:14 | 15:21 WAB | 15:28 WAB | 15:35 WAB | 15:42 WAB | 15:49 WAB |
At the bolded part, frequency is 7 mins, hence they can lable "7-16" because 7 mins is the minimum time interval. But this doesn't mean that svc 14 is running at a frequency of 7 mins, or 11.5 mins, all the while from 0831 to 1659.
In short, always check specific timetables for more detailed frequencies and timings, not just based on the 4 generic time zones.
Additionally, even with these departure timings from SBST website, you can never say they will be the real departure timings from interchanges/terminals. There can be various reasons for trips to be delayed, added or cancelled.

Hi mr array88, that is why I say must put Service frequency at certain timings in the subject title thread. If not, by just putting as Service frequencies, it may mislead people to represent average frequencies for services. This will imply the 4 column table which sbs transit used. Hope you understand. Cheers. Thanks.

Hi mr proudtobeme, the frequencies stated on website are true. The number of buses is fixed. The bus companies put the frequencies at 4 different categories of timings and cater the required number of buses for the specified timing.
What mr busanalayser is referring to is the frequencies for the services at certain 1-2 hrs zoning. What sbs transit is using is the range of frequencies according to the 4 different categories. Note that there is a difference in the way the two parties view 'frequencies'.
Frequencies of feeder sbs 382 and 386 in Punggol is about 10 min per bus. Read from the LTA release that there is a higher standard for feeder services. By 2017, all feeder services (I mean 100%) have to meet stringent quota of 8 min or less. No joke. Cheers. Thanks.

Ok in this case my bad... Sorry I didn't read your previous replies thoroughly.

Hi mr array88, this is where you are wrong. All sbs transit services use the 4 time zones to specify frequency ranges for bus services, irregardless of services passing by schools or not. For those passing by schools. The 4 times zones are just a representative of the frequency range. This means during a specific time zone, the frequency of 1 hr can be more than that of another hr. Which means from 8.31 to 4.59pm, 1-2pm may be more than 2-3pm, etc. However sbs transit will give a representative range such as 7-16 min. It just cannot possibly give a frequency range to represent every hour. Cheers. Thanks.
