Sensored traffic light junctions

[sb_rider]

I think it's totally a waste of money.

maybe we can write to LTA regarding the matter and make it more "sensitive" even to cyclists?

Cyclists???? For what, no number plate to capture.... Scare what???

[Lass]

a couple of times and esp late at nite, i just park the bike and press pedestrian crossing at junction to get the traffic working otherwise my tiny bike will not be sensed keke

[Exhaus-tion]

do a stoppie, the force of yr rear dropping might trigger off the sensor

[MiCmAsTa]

Waited for it to turn green on little road... But it never did....

marsiling lane junc to marsiling rd always like dat. i check blind spot den zoom!!

[MiCmAsTa]

The Little Road there wah liao... Waited and waited... Cos there got a Red Light Camera... Then LL wait... and wait... and wait... and wait.. Till got taxi come... Happy... But the green arrow for the taxi appear to turn left.... Then Red again.... KNN... Waited for almost 10 minutes...

if beat traffic light sure will hv bright flash??

Thats right... There will be a very BRIGHT LIGHT... Don't worry... You will not miss that FLASH LIGHT....

Coming back to the traffic light topic, i feel that i generally do not have much of a problem since changing from a wave to a super 4.. is it true that bigger bike more easily kena sensored?

[Guest nE0]

Jalan Kayu, the T-junction, left turn to Serangoon right turn to Yio Chu Kang road towards the CTE flyover...

 

The lights on the main road stays green, turns red, arrow appears, then dissappears, pause......... THEN TURNS GREEN AGAIN!

 

I waited there on a damp, freezing night in the wee hours after makan session, waited there alone like a fool for 3 WHOLE CYCLES, before I got off my bike and kicked the F#$&*(#@$^ pedestrain crossing button.

 

Damn pissed off. Where got traffic light don't turn green one? Cannot detect my bike? Then red light camera can detect right? What bullshit....

[weiz85]

i tried staying behind the white line n it works

[Metalfyre]

i always kick side stand, press pedestrain crossing button, go back and wait.

tried some of the posts' recommendations. like stopping not too front ahead & keep within the 'box'. still dun works. waited ard 15mins & this car came besides me, instantly turns green!!

[standlee]

realise the Clementi Ave 2?? (the only esso in clementi) towards AYE. at the single lane minor road turning to major road junction also same thing!! the traffic lights discriminate bikers!!!

[ghost04]

just put side stand dismount and press pedestrian crossing button. if not u don even know when the next car aka ur traffic light savior will arrive. green man comes u 1 bike pass but the light won't turn red so soon the green man will slowly blink and blink so let the cars across wait.

Stop within the tar lined boxes, depress front brake before stopping when front wheel is in the box works best. Yes its weight sensored.. Why would the boxes form up 2 or 4 rectangles just nice for the wheels of cars when it is electromagnetic sensored?

[Tyrian]

hey, i made some discovery about this issue..

 

in order for the sensor to work, no matter how heavy u r, it wun work coz it isn't based on the weight issue.. tested n proven by me at Woodlands 888 carpark exit..

 

so, this is how u should activate the sensor.. it is better to wear shoes with metal parts like those King's Safety Shoes.. (that's wat i'm wearing).. so here come's the instructions

 

1. stop at the centre of the box

2. put down both ur feet n juz place it or step ON both the lines

3. wait..

 

next method that i'm trying out without those metal shoes..

 

1. juz place ur bike on the longest line.. nearing to the kerb.. dat's wat i did

there's quite a bit of writeups on the net on this. do a search.. its definitely not weight sensored...

for those who wanna know what i mean, try waiting for the traffic light to turn green at woodlands drive 44 going towards woodlands drive 16,

I face this problem, too, at the very same junction!!!

[rae07]

well..last fri morning was stuck at this traffic light @ tampines for like 5min. reason: bikes are occupying the sensor area.

 

think it finally changes cos there's too many bikes in tt area.

[StingRhea]

from what i've heard is that if you have a strong magnet underneath your bike the sensor goes off faster. wonder how true?

[gnayed]

Er... No leh, I don't agree it's some metal sensor or what. If anyone have tried going out from the junction after turning left from Causeway Point, weight below 150 kg should not do the trick. (Btw, why is it always woodlands? LOL)

 

When I was riding vespa, the traffic light just doesn't turn green, and I had to bounce/jump my bike on spot then half a minute later it turns green (without letting my mainstand down). If it had been a magnetic sensor or what, the bouncing of my weight on the patch shouldn't make a difference. Now I never have this problem riding super 4.

 

Maybe junction differ from junction. Some use electromagnetic sensor and some use weight?

[StingRhea]

It might be an induction-loop trigger.

An induction-loop trigger is a length of electrical wire buried just under the road. Usually, the wire is laid out in a couple of rectangular loops resting on top of each other.

 

When a bike drives over an induction loop, it disturbs the loop's electromagnetic field. This changes the total inductance of the loop circuit.

 

This sort of field affects not only objects around the loop, but also the loop itself. The magnetic field induces an electrical voltage in the wire that is counter to the voltage of the circuit as a whole. This significantly alters the flow of current through the circuit.

 

The intensity of this induction depends on the structure and composition of the loop; changing the layout of the wires or using a different conductive material (metal) will change the loop's inductance. You can also change the inductance by introducing additional conductive materials into the loop's magnetic field. This is what happens when a car pulls up to the intersection. The huge mass of metal that makes up your car alters the magnetic field around the loop, changing its inductance.

 

The meter in the system constantly monitors the total inductance level of the circuit. When the inductance changes significantly, the computer recognizes this shift and knows that a bike has passed over the loop.

 

And because of the bike's size compared to other vehicles, aiming for the loops before coming to a stop at a sensored traffic light does help. The magnet improves it.

 

So now you know why the magnet comes in.

 

duhz. so you BOUNCE!
