Okay. Enough about 258, please.
All that 258 needs is just a capacity downgrade from DD to SD,
and an adjustment of frequency to match the other Jurong Industrial
Bus Services (excluding 256). That's all.
I would like to propose the following set of frequency for bus
service 258:
0630hrs - 0830hrs: 7 - 8 minutes (9 buses)
0831hrs - 1659hrs: 12 - 14 minutes (5 buses)
1700hrs - 1900hrs: 7- 8 minutes (9 buses)
After 1900hrs: 12 - 14 minutes (5 buses)
Reason:
Currently, with a full double decker fleet at eleven minutes
frequency, the capacity of 258 is 725.45 pax/hr (133 × 60/11). If
we change to use full single decker fleet, I would propose having
seven minutes frequency during peak period, so that the capacity of
258 during peak period would be 711.42 pax/hr (83 × 60/7).
Although the capacity during peak period would be lower, frankly
speaking, even the double decker buses now are not fully occupied.
After so long, the authorities probably have the data on what is
the average loading like during peak periods. If it is less than
711.42 pax in one hour during peak period, I think it is feasible
to use all-SDs and have frequency at 7 - 8 minutes.
During non-peak periods, 258 can continue to run at its current
frequency of thirteen minutes, except now it uses only single
decker buses. Capacity would be reduced from 613.85 pax/hr (133 x
60/13) to 383.08 pax/hr (83 x 60/13). Based on my observations, as
well as the comments here, I think even at reduced capacity, this
should be more than enough for non-peak period loading.
For the above frequencies, I propose 9 single decker buses
during peak period and 5 single decker buses during non-peak
periods. But, what are we going to do with the 4 single deckers not
in use during non-peak periods?
Alternatively, we can have 5 single decker (83 x 5 = 415 pax)
permanently deployed on 258. During peak periods, we can have 2
double decker (133 x 2 = 266) cross-over to 258 - but from where, I
do not know, maybe from 182. If so, peak period frequency can only
be at 8 - 9 minutes, at least still better than the current 10 - 12
minutes. Total capacity would be 681 pax/hr during peak period. If
average actual loading per hour during peak period on 258 is less
than 681, I think it can be done.
meanwhile, SLBP needs government-funded buses for bus services
transferring to Bulim Depot. So, might as well...
Seriously, only the authorities know the actual figures of
loading on bus service 258, through the data collected from the
EZ-Link card readers. I hope that they can refer to the average of
the actual figures and set the frequencies accordingly while making
changes from double decker to single decker.
Let's move on to discuss other bus
services.
Thank You.
Peak hours from 0600-0830/1630-1930 freq of 5-9 mins off peaks
14-18 mins..JIS off peak minibus also cannot full.Later you
complain waste resource.
