based on the picture, zest best station is STN03... although I find it weird the close distance between STN04 and STN03. I wonder where is the park for the Park and ride....interesting to see how the ramp turn out

Ya lor, park n ride only available for those Puchong stations :

Stn 06 - IOI Mall ( Multi-level car park)
Stn 07 - Tesco Puchong ( Multi-level car park)
Stn 08 - Rakan Muda Sports Stadium ( btw, where is this located ?)

I dont take LRT nowaday so I may be out of sync... but why would the STN3 and 4 is of worry for traffic when there is no parking available for the station? Folks either depends on buses or pick up. No different than other station with park and ride where there is more car. Having said that park and ride currently are tend to be located on major road with more lane which allow a bigger bottleneck.

Even if STN3 and 4 have parking, traffic will be horrendous when the Jln Puchong at TK will be using the LRT line. You better hope and pray they widen the Bukit Jalil bypass. Even currently that 2 lane in front of Zest is WAY Too narrow for comfort given the speed of the traffic.
