What is under the radar in this island for West side commuters during rush hour is that it could be made possible to reach Honolulu taking arterial streets faster than taking the H-1 during rush hour.  (Arterial streets have a speed limit of 25-35 mph compared to 55 mph at H-1 - but during rush hour, vehicles on H-1 start to crawl at less than 35 mph)

How?
* If all intersections on all arterial streets from Kapolei to Alamoana were remodeled such that traffic does not anymore stop for left turns. ***Left turns in a remodeled intersection are made simultaneously with traffic moving forward***
* If all traffic signal lights on all arterial streets from Kapolei to Alamoana were bundled into a single system controlled by Artificial Intelligence. 
(Note: - driverless cars are controlled by Artificial Intelligence)
