Intersection unit costs A base unit cost has been estimated for each intersection configuration. The base unit cost for an intersection is based on: the delivery of a T intersection, where a secondary road of equal or lower order intersects with a primary road; the delivery of 100 meters of the primary road; the delivery of 50 metres of the secondary side road; the signalisation of the intersection; and constrained road corridors.
