PRM_NUM_LNS

The default number of lanes in the Primary Direction is half the value entered for  Lanes Total above when the total number of lanes is an even number.   When the total number of lanes is an odd number, the default value for the number of lanes in the Primary Direction is half the value of the total number of lanes rounded up   to the next integer.   To change this default enter the RSAPv3 keyword "PRM_NUM_LNS", the beginning and ending stations and an integer value between 1 and the total number of lanes. For example, a five-lane Divided Highway with three lanes on the Opposing Direction (i.e., decreasing stationing) and two on the Primary Direction would be entered using a combination of Lanes Total=5 and PRM_NUM_LNS =2.
