So what are those new white beacon things in the tunnel?

[play r 32]

Drove through the tunnel last and didnt see anything suss, but as i came out and was driving down orong rd i saw something bloody sneaky. The cops were parked up on one of the overhead bridges. The cop in the passenger seat was leaning out of his window with a handheld! Soon as i saw him i realised i was doin 8-10 over. I was wondering what there plan is when they do see someone speeding from up there though? do they have a recording device on the hand helds? Or were they waiting for someone who was speeding a lot and then the would fly down the ramp after them?

[SKYRYAN]

Yeah they come down the ramp and chase you I think, I've seen them up there before too..

[dan_the_man]

lol yeah the come flying down the ramp like idiots. its pretty funny to see them cutting people off to catch someone doing 10kms over the limit.

Slight Hi-Jack!

If you are heading north on GF-FWY in line with the Burswood Golf Course I see the Blue Poison sitting high and dandy on his motorcycle clipping people then chasing them down towards the tunnel. Now in the hand book for the Silver Eagle Hand Held Laser Speed Recording Device - It states that the device must be used on a horizontal plane and not up / down hills, across oppisite lanes of traffic, or to be used in rain or fog like conditions. Mate got done in NSW on his Crotch Rocket, He fought the law and won. Bought the manual from the U.S of A and challenged the copper. NSW Police paid fee's and court costs.

interesting point mark. They would of had it on at least a 45 degree pointing on me. They must have been wanting to get someone who was really flying though.

Cough Mike Cough

haha yeah for once i was actually great full i was in the bloody focus and not the "bright yellow/come get me" skyline.

Standard issue laser for WA is the Ultralyte LTI2020... not that it would operate on different principals... laser is laser... just wanted to jack the thread too!!!

They have been doing the "over bridge" trick since the poly opened.. I have heard of them doing it on the Kwinnana Fwy too... bastards!

Looks like we are not the only ones getting hosed....

The reason there is no speed cameras in the tunnel is because the stuff that the walls is made of is to reflective so photos would just come back as a white screen. So you can do whatever speed you want...

I once had a 180 overtake me in the emergency lane.

My brother lost his license like that. I used to work at Burswood for 3 1/2 years & I seen them on top of that bridge a few times, during all different times of the day. Used to get stared at all the time at 4 in the morning as I drove past them. Occasionally just a car, sometimes 2 bikes, sometimes both with two on the bridge with radar guns for both directions & the bikes waiting on the down ramps.

I thought the hand helds had to be used in a specifc way to get an accurate reading. Not just point and press. Same with multinovas, very picky as to how they are meant to be set up.

Cheeky f**ks.

im pretty tuff eh

[infamous_t]

Ive seen them parked up on that bridge on the way to work some mornings, sneaky buggers...

But the best & most sneaky spot was opposite Leedy train station(Northbound), parked in the bushes - offroad adventure!

Multanova's need to be setup on a certain angle otherwise there speed reading is thrown way out (google radar cosine error for more info). Not sure if Lidar is affected by it as well, at least not to the same extent. Cosine error makes the camera read less, not more . Sweep error (e.g panning from one headlight to the other) when using a lidar gun will add to your speed, which is why trees can be caught speeding.

My god, how you all speculate on a topic you obviously know not much about! (Not that I do either) You're all clutching at straws!

Reflectivity/Angles/drag-coefficients/flux capacitors.

What a silly silly thread to begin with!

[MearCat]

Back onto the subject at hand ... The tunnel...

From Main Roads Bulletin web page :

"TUNNEL TEMPORARY CLOSURE - Northbridge (Graham Farmer Freeway) Tunnel closure

The Northbridge Tunnel will be closed during off-peak times to enable an upgrade of tunnel management and traffic control systems. The planned upgrade is required to keep up with advances in technology and minimise any future problems and possible tunnel closures due to system breakdowns. This is in line with the aim to keep Perth's Northbridge Tunnel one of the safest in the world. The upgrade will require the periodic closure of both the eastbound and westbound carriageways of the tunnel to install and test the new computer systems and associated software."

But as yet, there are NO cameras in the tunnel that are specifically used for speed detection.

The reflective thing is not my opinion... It is the facts

[Ashy Larry]

Reflective? What like MC Hammers Pants??
