The arrows are drawn following the analog Clock to gives a feel of directions. E & F are 11 & 10 O' clock while K & L are 1 & 2 O' Clock respectively. G & J are typical symbols used on the road hence, I have included it as an entry. You can check more than one direction for the Lane as some roads do allow multiple turning. This will lower the number of Arrows need for the Generator.
These directional Arrows are guides only and we need to fine tune what's needed. We can also change it to whatever necessary to ease LA Administrator's work. The lesser the arrows the lesser the codes I have to write...
