Dapat, the southbound bus stop should be placed at the Pasay side where the MRT station is so that the problem of buses crossing 5 lanes to get from the San Lo side to the Pasay side would be eliminated.

Put the bus kulungans on one lane in the Pasay side and eliminate the kulungans on the San Lo side. The buses don't use these anyway and go around these with impunity, causing heavy traffic and a maddeningly free space up towards the Alabang up-ramp.

Then put grills along the length of the San Lo side so that there wouldn't be a chance of picking up any passengers there.

I don't think it's such a long trip for pedestrians to go up into the MRT station and down to the Pasay side.
