LA stoplights synchronized but road war endures

May 25, 2013 by John Rogers

It seems the impossible has occurred: The nation's most congested city has become a model for traffic control.

Gridlock still prevails and drivers' blood pressure still spikes as LA's traffic arteries seize up during morning and afternoon rush hours.

Yet, with the flip of a switch earlier this year, Los Angeles became a worldwide leader by synchronizing all of its nearly 4,400 stoplights. It is the first major city to do so.

The result: Drive times have been reduced by 12 percent across major LA traffic corridors.

During rush hour, however, it's still hell to cross the City of the Angels by car.

The problem, according to officials is this: only works well when the streets aren't so clogged with cars as to make them almost impassable.

Wow, for the last 30 years I've thought this is standard issue in all cities with more than a half million population!

I sure hope they are wrong and not I.
