Kelvin Road train crossing..Interesting sight!

A similar setup is planned for Welshpool Rd, they may already be in place I don't know.

Sensor loops are in the yellow crossing mark sections of the road. The camera takes high def photos and video of cars when the booms are activated. These are automatically sent off to wherever. The PTA Control room can also get a live feed of the crossing via the second camera.

Had a feeling that may be the case...

Ahem. trialed

Does the PTA have the authority to fine people under the RTC for avoiding boom gates? Or do they have to take the footage to the police who use it as evidence to fine drivers...?

I thought red light cameras used induction loops?

I think it would be fair to say that all in ground triggers for electronic equipment (eg cameras, gates) are induction loops (wires placed in a loop under the surface), as any sort of 'weight' sensors would rely on complex mechanical devices, prone to damage and malfunction. An induction loop is simply triggered by a metal object passing over it, and is easily installed by cutting the surface, placing the wire in the cut and sealing the cut. This is what you see in the bitumen at intersections controlled by TCLs and at electronic gates. Any sort of weight trigger would involve some sort of excavation and surface replacement.

That does sound more feasible, I must admit that that's the way I'd always been told it worked, and thats the way I figured it would work, makes sense. A metal push bike can trigger TCL's while a carbon fibre one won't, weight might be the issue, but I think the road would have to move a fair bit to detect the weight of vehicles etc.

Gav,

You might find that becauase the offence takes place on PTA Property that they can prosecute for the offence. There is an offence under the Public Transport Authority Regulations for not obeying a signal or sign.

I fined a couple of people for driving around the boom gates when I was a Transit, only when I witnessed it myself.

Just out of curiosity, daz, what's the fine worth?
