traffic light variations

ATLS wouldnt be compatible with 4 or 5 aspect so they are omitted

Single Mast:

Single 3 aspect

Double Right 6 aspect

Double Left 6 Aspect

Double 6 asp tram

Double 6 asp bus

Dual Repeater Masts:

as above but x2

Typical Intersection:

4 way: 12 Dual  + 4 Single (16)

T intersection: 6 Dual + 3 Single (9)

Dual Carriage way incur an extra Single per direction on the island,

4 way: 12+4+4 (20)

T intersection: 6+3+3 (12)

So for a 4×4 city block thats 512 installations

(32×4 way intersections(x16))
