We are now in the 16th year of the21st Century and when it comes to traveling on the highway or streets with traffic lights and Left Turn Arrow traffic light at an intersection there are today Hi-Tech solution and innovation to Traffic Congestion, improving traffic flow, or increasing the capacity of a street or highway WITHOUT new construction........  In Utah today, the 21st Century, for example, there are intersections where drivers make a left turn simultaneously with drivers moving forward. Everyone who drives in this island when crossing an intersection with a Green Arrow traffic light all have to waste time waiting an waiting for a line of cars to finish making a left turn before a driver can move forward.  Imagine the time saved if left turns can be made simultaneously with others moving forward?  at 2 minutes wasted per intersection we're talking 10 minutes in travel time saved from 5 intersections without a Green Arrow.
