But as far as the traffic regulation in those communities, it's a matter of choice and safety.
If the traffic experts determine there is a need for more signal changes, longer durations, or more directional signals, the communities make the decision.
I know of several smaller towns where there are blinking lights, slower speed limits and/or working signal lights designed to keep a little regulation 24 hours per day.
I've even known of a small town using a fake police car with a dummy officer inside, just visible around the corner of a building, to cause motorists to do a double-take and slow down as they passed through town.
Adjustments can be made in a town's signals, of course, if the experts are convinced they need to be. If drivers think changes are needed, they can let the city or town officials know in writing or by phone.
Otherwise, as we have done here, we can point out the situation and hope those involved will look it over themselves if necessary.
Enjoy your week and drive safely.
