Please comment.
General observation: ALL roads allow Left, Straight and Right turns. At the (assumed) traffic lights, these roads have three lanes. IMHO, nodes 'Jct-01' and 'Jct-04' are too close to the 'first' turning. 'Jct-03' looks about OK. 30m from the U-turn?
[Jct-01]:
Left lane is for a Left-turn or straight;
Middle lane is for straight only;
Right lane is for U-turn or Right-turn only.
[Jct-02]:
Left lane is for a Left-turn or straight;
Middle lane is for straight only;
Right lane is for a Right-turn only.
