printing the $us, page-4

ricky, after a contract is signed the city and Redflex survey each approach that has been suggested by the city.
As well as having a record of accidents an approach has to show enough violations to warrant the expense of installing this expensive equipment.
The company has a substantial data bank now and can pretty accurately predict what drop off there will be in violations over the life of a contract, even state to state this varies, seemingly in proportion to the size of the fine. For example in Californian cities where the fine is $340 there would be a much faster drop off than the East coast cities where the fine is $50.
End result is the company will only install at an approach that warrants it, if that means 10 instead of 20 that's great by me, they're looking at the bottom line. Actually when accurate surveys are done very often other approaches that were not selected by the city turn out to be OK for cameras.
Also very often a city will only initially install say half or even a quarter of planned approaches which gives them time to get all their electronic systems going, police, courts, motor registry, etc and iron out any bugs to fit in with the Redflex digital system before a large number of citations start to flow.

It's quality, not quantity, that counts, there's plenty of business available, why settle for sub standard approaches?
