Bro Ong,
By looking at the "Sengkang square" again.
The pt AB opening is missed to join up.
The pt AB opening is strictly meant for SBS buses to move out from its Bus Interchange through AB opening i.e. from A to B directional traffic flow.
No U turn is allowed for both directional traffic flow i.e. A to B or B to A.
No right angle turn is allowed for the cars moving from B to A and straight into the SBS Bus Interchange premises.
Thanks.
If to study the above mentioned conditions further, it seem to be the best with out joining the link pt A and B to fulfill all the conditions by treating it as a normal 2-line road as usual. At this junction pt AB it installed with the traffic light.
Joining pt A and B may seem hard to fulfill all the conditions and make the routing inaccurate.
This link pt AB is meant for the SBS buses only and not applicable to the cars routing.
You are right not to add the link in this sense.
Thanks.
Done! 185 - OngCC
