Width of the corridor is a factor...
Idealy you want to pie both corners as you approach them... if the corridor is wide enough... you can do that on the same side as you are..
If it is narrow as illustrated , you can do the crossed arcs as you illustrate.
Once you have observed as much as possible... then you can enter the hallway left and right at the same time...
