The standard Hawaii DOT traffic engineers traffic light solution is not how any lights should be installed along this highway. Traffic lights cause more accidents than they prevent and needlessly waste fuel.
Since none of the intersections are 4-way, this is how they should do it.
Southbound traffic should not be stopped for any of the traffic leaving HPP. All of the roads out of HPP should have a right turn merge lane headed northbound. The traffic lights should only stop the northbound traffic, when a vehicle wants to turn left out of the HPP roads with a corresponding merge lane installed for those southbound vehicles.
Do just the opposite for the intersection at Orchidland, in this case, only stopping southbound highway traffic and allowing northbound traffic to continue unabated.
This solution should also be applied in front of the credit union. Stopping both sets of traffic so one car can pull out, is ridiculous. Another location is the 2 highway split by Keaau, which has no reason why traffic going from Hilo to Keaau/Volcano needs to stop.
