Force network analyst route to follow a certain pattern

I'm using ArcGis 10.4.1 and network analyst. I'm trying to force, network analyst route to follow a certain pattern (My purpose is to construct a route that will have very few turns )

I've tried editing network attributes in network dataset properties and changing values in Global Turn Delay Evaluator, but with no success. Instead what network analyst produces is shown below, as you can see the calculated route makes no sense. Try to locate stop no11and the stop no10,  (spotted with a red circles). In addition even if i add a line barrier with scaled cost there is no apparent result.

Is there any possible explanation why network's analyst algorithm behaves like that? Can anyone suggest me any solution. Is there a way to hard code the route behavior?
