Ok lots of rules, how do they interact.
First up, lets take the rules for Tank Traps
So, they are treated as impassible terrain to all non-skimmer vehicles. A walker is a "Vehicle, Walker", and therefore is a vehicle so must treat the tank trap as impassible terrain.
Ah ha! But, they move as infantry, note that they move as infantry does. Not that they "count-as" infantry, so we look at the rules for infantry movement and they are the basic rules. There is nothing in the basic rules or the infantry rules that enable infantry to move through impassable terrain. It talks how they are affected by dangerous terrain and that they may not pass through impassible terrain.
This enables to take into account the rules for infantry movement and the rules for the tank traps without causing conflict. The walker moves as infantry but is still prevented from moving places by impassible terrain.
