Low tech. They are a set distance apart. The copper in the plane uses a stopwatch to time how long it takes a car to travel from one set to the next. If the car gets to the next set too soon, copper radios to a mate who pulls the car over.

Thanks for this clarification, in this case a plane or a helicopter has to fly on a low distance from a ground to spot those line easily otherwise they won't be able to see them.

The plane was at a reasonable height, a guy challenged the system in a WA court & won, there was too much error because of the plane's height, hand stopwatch etc so it was dropped.

^^^ Yeah, but that sort of thing is a rarity - far more get booked than get away with it, even if they argue it in court! And it doesn't necessarily need to be an airborne watcher, it can be someone stationed on the ground, just so long as they have a good view of both the start & finish marks!!

Then again, many more unmanned 'point to point' camera systems are being installed around the country, they just take a pic of each vehicle/number plate as it goes past, recording the time & date, then some distance down the road (5 km or maybe 105 km, doesn't matter) there is another camera that does the same thing. Both sets of pics are compared to see how long each vehicle took to drive between the two points and any that did it quicker than the speed limit allows score an expensive letter in the mail!! I believe Highway 1 has been prioritised for this, but it's happening all around the country.... :(

They did it around Taree NSW during the late 80's. It was rather an expensive way of policing, putting a few police and a pilot in a plane flying around for a few hours. They could only do it during clear weather and in the middle of the day which further limited the effectiveness.

I think it turned into joy flights for the traffic cops, anyway it was dropped but the signs stayed up. Same as lots of signs warning of cameras, to instill fear that you may be spotted in the hope of changing behavior :worry:

If you want to change driver behavior, you still cant beat a uniformed cop in a marked car... or some random bloke on a white BMW touring bike.

If they are still using it would need to be that the officer who intercepts and writes the ticket needs to be the one who detects the offence - from start to finish - or the chopper lands and the guy in the chopper speaks to the driver and writes the ticket.

I think the real issue with that type of booking is that the guy in the chopper/plane witnessed the offence and then the guy on the ground wrote out the ticket based on the evidence of the guy in the chopper.

The guy in the chopper is the actual informant of the offence and the guy on the ground is alleging an offence that he hasnt actually witnessed.

Which is "hearsay" and inadmissable in court - its a basic tenant of our legal system.

Also the offending motorist cannot check "the reading" , the stopwatch, to ensure that it is x amount of time as alleged by the guy in the chopper as you could if it is a radar on the ground .

If challenged the guy in the helicopter would need to appear in court to confirm the offence but the ticket would indicate a different officer intercepted the vehicle, spoke to the driver and wrote the ticket based on the information of another.

Nor is it admissable if the stopwatch is not a certified chronometer and has not been checked regularly for accuracy as are other speed detection devices. There are other issues with manual devices

And the measured distance needs to be measured with a certified tape measure ( metal ) and its accuracy needs to be checked on a regular basis to ensure that it is correct.

And those certifications need to be accepted by the court.

Too many issues with manual time over distance - other methods are more certain.

Chris , a lot of very valid points .
i think the whole idea is that most people will not challenge it , ; ie go to court .
either through ignorance or dont care enough about their rights ,
i have had a similar situation with a mobile phone , i was not using .
challenged it with info , prosecution dismissed .

and i was not using my phone , which is why i fought it .

Kerry,

as i said, "IF" they are still using that method, given that its so easy to challenge I would be very very surprised if any states use it anymore. So I doubt that too many people would have to worry about challenging that type of booking.

Realistically , the whole Speed Camera in the Sky was an awareness program - flying a chopper at 400 bucks an hour plus Pilots & two Coppers wages plus Vehicles and the cost of any contested matters was an expensive way to get a booking / revenue. Not cost effective in todays business orientated policing parlance.

But as proof that it worked as an awareness program is the fact that those white lines are still being discussed :lol:

Re mobile phones, I was involved in a minor prang recently as a passenger, and stuck to the top left of the windscreen was a in-car camera which happened to record the other driver for approx 2 sec before the prang and very clearly at the moment of the prang with a mobile phone held to her ear.

When i mentioned it to her immediately after we got out of the vehicles to exchange names and addresses , as I had actually seen her on the phone, she flatly and vehemently denied it outright.

I said nothing about the camera as I didnt at that stage know it was there

Silly girl , damage did appear minor , it was a corporate car and the insurance company is now after her for an "at fault / she pays" claim and requested the footage and a statement from me ...........the company driver wasn't even going to say a damn thing about it, he thought the damage so minor that it wasn't worth the hassles .

When she denied being on the phone I convinced him to report the prang to his boss and insurance

Oh, He was wrong apparently - new cars are so expensive on parts and paint :eek: - she has nudged the whole front end a tad to the right :lol: :lol:

A lot of your first post is kind of irrelevant anyhow.

As discussed in another thread, evidence as such is not necessarily required as the officers can estimate speed.
No need to have a calibrated or certified device be it radar/tape measure/stopwatch etc.

Timmo,

If you want to go around in circles again feel free to do it all on your own - they are two different issues.
