Over that last year Car & Driver has run a couple of articles on the
subject.  Their contention is that cities have had good results by
lengthening the yellow from 3 to 5 seconds.  They also claim that the
contracts several cities have signed  with intersection camera firms
specifically outlaw lengthening the duration.  Sounds like revenue
generation rather than accident prevention to me.

I hate people who run red lights, but I don't feel that a camera which just
takes a snapshot is the best way to solve the problem of accidents.  The
rear-end collision rate has gone up some places, which a longer duration
yellow should not do.  Multiple pictures makes a lot more sense.

It does seem that some traffice enforcement methods are more for generating
revenue than reducing the accident rate.

I would much rather see the police ticketing people who drive erratically in
traffic, don't signal, and drive through red lights instead of just sitting
on a rural highway with a radar gun.

A recent program on the German autobahn showed police ticketing people for
driving too close to the car ahead.  More of a cause of accidents than
driving fast.
