Why would a group of engineers at PAX determine that the need for a third lane would be delayed if the lights were timed? That doesn't make sense. All they are (I was) concerned about is the minimum transit time. Any additional lanes would only minimize that. Besides, I don't think there are any road engineers at PAx.... maybe a rocket scientist ot three.
The people that set the lights on Rte. 235 are probably the ones that determined the parking req'ts for the IPT, and north and south engineering buildings on base.
