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.
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.
