Araneta corner N. Domingo, San Juan

Here's a major choke point.  I've wondered why no one cares to fix this; perhaps it's more complicated than it looks to me.

What happens is we have a four lane south bound Araneta avenue going into a two lane street on either left or right.  Vehicles going to the right aren't the problem.  What is really the issue here is that the four lane avenue, despite proper lane markers and left-turn/right-turn signs, is transformed into five lanes going to the left, and one lane going to the right.

It doesn't take a genius to simulate what that ensues.  Five lanes all turning into two lanes is a lot of merging.  What gives?

Perhaps MMDA can make physical barriers to reduce the converging lanes.  Or perhaps they should take lane division as a traffic offence.  Seriously.

Quezon Ave. D. Tuazon U-Turn Swerves

MMDA's  Quezon Ave. U-turn slot implementation has been successful in increasing traffic throughput and average speed. Unfortunately, some drivers have come to abuse it, swerving from streets too close to the slots, or even doing counter flow shortcuts to get to the u-turn slots. 

At the Quezon Ave. / D. Tuazon U-turn slot, a lot of cars and trucks routinely go out through Speaker Perez to do a U-turn in Q. Ave.  While this is fine and dandy to those who go through this route, it seems to me a selfish manuever that causes much slowdown to the traffic plying Quezon Ave towards Espana...

Perhaps, MMDA should set guidelines as to what is considered swerving, perhaps paint lines to indicate allowable usage of the U-turn slots.
