SPEED LIMITER
-
is there actually any speed limiter on SMRT buses??
cos b4 i took this pic, it went up to 80km/hr..!
photo was taken in SVC 190 merc 0405..

I have also been on an 188 bus along AYE and have seen the needle go up to 70km/h. When I got off the bus and looked at the windscreen, it did indeed have a speed limiter sticker on the windscreen...
I have also seen SMRT buses with no/not working door interlocks... I have seen Nissans/ELBO Scanias moving with door open. And I even took a Habit with its most rear door open when moving at normal speeds on 187...
BTW, in that picture, what's the word/figure on the orange speed limiter light? -
its written 70km/hr on it.. it flashes when it hits over 70km/hr.. but i think like no use lor..Originally posted by stooper:I have also been on an 188 bus along AYE and have seen the needle go up to 70km/h.

The fastest I had was 75-80km/h actual speed on a DAF on 985, TIB69XX one... And cameo, cos I dun want to have trouble like the previous people, I follow them not to put exact rego, haha, actually any DAF can...
And that looks to be a batch one Hispano Bendy, hmm...
Bendy on 61 also go try before, erm, 60-65km/h actual speed on Ulu Pandan Road.
All speedometers, AFAIK, displays 105% of (actual speed)-->also known as true speed, in Singapore. Only Police/Government vehicles have exact speeds displayed. Hence 70km/h on speedometer means 66.5km/h true speed. -
i also saw a SG coach running at 80km/h at BKE. Overtake here and there. 80km/h my god, and it never slow down, except when want to exit to get to woodlands.
There's even another case where some drivers tamper with their speed limiters and as a result, the meter always stayed at 0 although he might be running at 70.
strangely, MS coaches with are not fitted with speed limiter only run max 60 on our expressway. -
If stay at 0 means tampered?Originally posted by XTransbus:There's even another case where some drivers tamper with their speed limiters and as a result, the meter always stayed at 0 although he might be running at 70. I thought is just the speedo spoilt! 
I have seen quite a few SBST buses with the speedo remaining at 0. On some Volvos, the rpm also stays at 0. So when the speedo stays at 0, the limiter doesn;t work? -
u mean those wif jammed gearings?
-
No. Everything is normal, just the speedo remains at 0.Originally posted by SBS9888Y:u mean those wif jammed gearings? -
scanias and most mk2s dun have speed limiter... SMRT DAFs can speed up till 100 if i not wrong or even higher... only got buzzer sound tee... tee... but v. annoyin
-
some O405s can cruise up to 70-80km/h on a downslope without acceleration but will slow down to 60km/h when the slope evens.
-
All buses including the Darts can exceed 70 km/h easily,But again this is SG,The fastest i travel is on Malaysian Coach @ Negri Sembilan where the driver whack 150km/h,I was thinking whether can i back home in one piece or not
-
Vehicles on the opposite of the road look always faster, so can joke with urself and take taxi at 100km/h, then the opposite road a DAF speeding at 70km/h would sound like 170km/h, haha...
I saw VO3X with speedometer and tachometer spoilt at same time, but most cases its only one at a time. And SMRT 0405 speedometer would lag at times, when its 20km/h the needle jump up rapidly, low speeds are not recognised immediately. -
that looks like a high beam light
-
nope.. its 70km/hr.. i think it faded off so they jux used liquid paper to write again lor..Originally posted by SBS9828X:that looks like a high beam light -
this picture looks as if it could be parallax error. dunno but sometimes for expressway playing buses... they shd go at least 70. 60 is too darn slow
-
Simple way to get past speed-limitor:
Disengage gear downhill. I watched the perm VSOs on 161 go past 85km/h. Watch out for this particular BC who knows this trick! -
High beam light is usually blue...Originally posted by SBS9828X:that looks like a high beam light -
wat is parallax error???Originally posted by storm_freaky13:this picture looks as if it could be parallax error. dunno but sometimes for expressway playing buses... they shd go at least 70. 60 is too darn slow -
yeah.. SVC 171 always does tat.. but on this bus, it did not do it.. it was on a straight road..Originally posted by SBS3625D:Simple way to get past speed-limitor:

It's when you see something at an angle... Since the needle and the speedo readings are not flat, when you look at it from an angle, it might be a bit off...Originally posted by manjieass:wat is parallax error??? -
Simply, it means not reading a reading on the same plane as the indicator. In the case of a speedometer, you read PERPENDICULAR to the measuring apparatus. In other words, immediately above the reading. (Not vertically above, speedometer is slanted). To correct parallax error, what some instruments have is a mirror. If the needle is seen in the mirror, it shows that there is a parallax error because of the laws of reflection, blah, that I won't explain. I would need a diagram. If only I can upload a simple diagram,Originally posted by manjieass:wat is parallax error???

ok thanks.. btw, when i took the photo, my cam was around my chest..Originally posted by stooper:It's when you see something at an angle... Since the needle and the speedo readings are not flat, when you look at it from an angle, it might be a bit off... -
no need a diagram.. i understand liao.. pai seh.. years nv touch books/science liao..Originally posted by Donavan:Simply, it means not reading a reading on the same plane as the indicator.
