As a pro chauffeur for the past 30yrs. I've learnt red lights are no good bc they stop the flow of traffic...A roundabout "system" will not.
As a pro chauffeur for three decades now, I've realized that red lights take away from my life span due to the amount of time I've spent behind them.
Roundabouts are used all over the world to keep the flow of traffic moving ...unlike red lights which lock up traffic like a blood clot in a clogged artery. I think a roundabout "SYSTEM" can best serve a crowded city with no room to grow. A roundabout system doesnt have to be your typical roundabout in circular form for this would be extremely costly to construct. My idea of a system would just to be not allowing four way crossings at every single intersection, rather one way turn only turns with a roundabout lane a mile or less down the road so you can turn to your desired direction. This would eliminate long stops at red lights and best way to attempt to keep the flow of traffic moving. The cost would also not be as much as constructing typical r/a's with only small road modifications required. These could be built and designed all over Miami-Dade county after realizing where the heaviest backups take place. This would be a little annoying to the drivers who will have to go a little way out of there way, but in the long term will save gas, electrical energy on the power grid by reducing the amount of signal lights, and most importantly time by reducing the amount of time spent behind red lights. Keeping traffic moving as much as possible at all times will surely help to reduce traffic in a major city like Miami or Miami Beach
