Speed Limite Enforce by Aircraft...
 

hmm interesting.

I don't know if anyone is aware but if you spot a police helicopter and your speeding it can actually record your speed and have an NIP in the post by the time you get to your destination [yes]

just a little bit of not so known information for the fellow brit drivers

How does it record your speed exactly?

Doppler radar, perhaps.

They do it by road markers and Speed = Distance / Time

Why would they be using multi-million pound aircraft, costing how many thousands to run, just to monitor speeders?

Rofl, love the picture!

I was just in Virginia last week and we were going down I-66 towards Washington D.C, anyways I see that sign on that stretch all the time what kind of aircraft enforces speed would it be a drone type aircraft circling the skies high overhead?

They don't.

From what I understand they will put a small Cessna overhead, and have a 1/2 mile segment of the interstate marked. They simply record the in/out time and find the average speed.

Of course this is incredibly expensive, and they rarely actually fly the planes. Its basically a deterrent via a cool sign.

because they can get you without you even knowing about it,meaning they can collect speeding drivers without even the slightest whiff to them that they've been nobbled.

they have a special Radar and a special ANPR system that can read your number plate 700ft+

they have been doing it in Essex for quite some time and even have signage that warns you of airborne traffic enforcement.

they spot you speeding they follow for a bit then pass you onto a traffic police car in the Area then they pull you over if your super over the top speeding wise.

although just recently there have been a lot of complaints about the cost of the helicopter (£1,000 ph) to run for this purpose but if you think about it all it has to do is hover for an hour over a buisy motorway and scan with its hybrid ANPR RADAR and catch 16 cars per hour and anything over that is pure profit.

They have those signs here on Vancouver Island. Over the four years that I have lived here I have never seen an aircraft overhead or heard of someone getting reported by aircraft, but it does make me paranoid.

Picture is almost as old as I am (not really). I remember seeing this a number of years ago. Still a cool picture.

Ive seen similar signs near the DIA airport
