SBS Transit's iris system

2 more days to IRIS

Yeah! The frequency from 8.15 to 8.35 (and also 9.05 to 9.20) is an average of 1.5mins! So the buses already start bunching at the boarding berth there!Originally posted by chickenlittle2:Some svc like svc 179's time schedule would be in a great mess in the morning. At about 8.20am, u can see more than 3 buses bunching together and passes through. So how to provide real time information correctly?
It is made even worse by the 180 bendies hogging up the entire place...
Even the old TV which displayed the time (which dunno disappear where now) couldn't even clear the bus regoes fast enough. It sometimes skipped a rego because after scrolling through the 4 pages, the time was already over!
And also the timing of 179 buses would be highly unpredictable. If the order of buses leaving BNL is A, B, C, D, it might arrive back as D, C, B, A! So the timings of IRIS would keep on jumping up and down as buses are overtaking each other, then overtaking back! -

skaly IRIS is Idiot's guide to Route Information in S'pore -
Erm.. the system would likely be involving your handphone..Originally posted by chickenlittle2:Is the IRIS system installed in the bus int or in the bus or even the bus stop? -
It's something like *655?Originally posted by sBs_boy:Erm.. the system would likely be involving your handphone.. -
This system in place, see how they can carry on lying to commuters to cover up complains

Was just about to post that!
Wonder how accurate it is (must be accurate to at worst +/- 5 mins but not too accurate because we dont know what exact time it is based on)...and how does it generate the info...
I want ONE Bus company. Two bus company is sickening, especially when one is living in SMRT territory. Cant experience all these innovations, and vice versa for those living in SBS transit territory, cant experience the SMRT next bus stop displays... -
pretty accurate, playing with it now with the bus stop downstairs... very fun....
the wonderful thing is the lite version, which will come in useful when u're physically at the bus stop... -
any idea whether smrt will be having a similar system too?
-
oh yes, to read it, the subsequent timing which says 20 minutes actually means 20 mins after the first bus has come, which means 36 minutes from the time u accessed the system...
-
it uses GPS to determine its location and then uses GPRS to update the location back to the operations center so it will be pretty accurate.Originally posted by ignoramus2006:Was just about to post that!

it seems to jump to 'Arriving' when it's 1 minute, and the wait can be confusing cos the bus may not be in sight yet... more testing is needed tomorrow on the roads i suppose..... -
if the current bus is the last bus, it will show
Next bus: 13 mins
Subsequent bus: no current prediction
using the lite version, on phone or PC, is very fast.... -

Update: Services will not be listed only on their days of non-operation.....Originally posted by ^tamago^: -
i just tried it out for my journey to campus later and it also indicates if it is a WAB.

Very interesting system - playing and experimenting with it a bit right now before I go back to camp. Not something original, but I feel it's long overdue that we have something like this.
The system also seems to tell you whether the next bus will be non-airconditioned too.
Hmmm... I wonder if anyone will make a Kofabulator widget out of this, seeing that it has already been done for similar systems in other countries...
I think SMRT will never do this though. Money and stupid gimmicks are more important to them . -

A wait off your mind
Poly students invent system that lets commuters know where a bus is along its route
Gracia Chiang

TIRED of waiting for buses? So are three final-year students from Ngee Ann Polytechnic. That's why they developed a smart system that allows commuters to track where a bus is along its route.
.
"Usually, people don't like taking buses because the timings are so unpredictable. When we miss a bus, we're not sure whether to take an alternative route because we don't know when the next bus is coming," said Mr Christopher Choo, 19, one of the students behind the project.
.
Collaborating with the Land Transport Authority (LTA), he and two electrical engineering teammates, Mr Du Si Jun, 25, and Ms Cheng Xi, 20, have come up with the Intelligent Bus User System (iBus), which extracts data from bus-operator servers.
.
The system makes use of plasma screens installed at bus stops to indicate if a bus is six to eight stops away, and it is programmed to alert commuters when a bus is approaching.
.
The aim is to help commuters — especially the elderly, who may not be able to see bus numbers from afar — flag the bus in good time.
.
There is also a space for advertisements, a map showing the buses' real-time movement and a news ticker on each screen. In addition, a SMS function allows commuters to find out the location of a bus or request an alert when a bus is at a certain location by sending a message.
.
"If I am at the library, for example, I could ask it to alert me when the bus is three stops away, so I can pack up and make my way to the bus stop just in time to board," said Mr Choo.
.
But it could be six months before the public gets a look at the iBus trial system, which will be set up at the bus stop outside Ngee Ann Polytechnic along Clementi Road.
.
The three are still looking for $50,000 in funding and will approach SBS Transit with a proposal.
.
The operator has its own service that lets commuters check bus arrival times via their mobile phones. When contacted, SBS Transit would only say that it "welcomes innovations that enable us to deliver better service".
.
SMRT was also non-committal, saying: "There are many factors to consider, such as operational feasibility, compatibility with our existing system and economic viability."
.
The LTA said it would have to conduct vigorous testing and improve the prototypes before the system can be adopted.
.
Meanwhile, the team will focus on ironing out issues such as how to prevent theft and vandalism of the screens.
.
But if an interested company wants to take over the effort, said Mr Choo: "We'd be more than glad. At least we managed to help the public." -
how's the report for the day?

Kinda cute

Saw it... Looking at Sv 6
Next Bus: 7 mins
Subsequent: No current prediction
Bus Stop: Downtown East
Now it shows: Bus Arriving -
Hey hey..
Sv 170 the furthest you can enquire is till JB CIQ
And if you check for svs like 90 now, if the bus stop you choose, the subsequent bus waiting time is abv 60 mins, you see "No current prediction" as well -
5 years later , just like microsoft come up with a replica of the IPOD , 5 years too late . lolOriginally posted by the_unknown:any idea whether smrt will be having a similar system too?
or maybe never .
