time and length impedances

Hello,

I built a network data set and then activated global turns. I was interested that no "Reverse" turns were possible (like between roads that form an angle smaller than 30º for example) so I applied a very high penalty for reverse turns. But when I calculate a route I see that still the slowest (but shortest) route is generated. For example, the final route (with a reverse turn case) will have 2000 minutes of drive time (because of the turns penalty) while if a put a barrier to force the route to take other roads in order to avoid the reverse turn, the alternative route is much faster, like 4-5 minutes (lack of penalties). But still the slowest route is chosen, despite the penalty!

In the properties window I have selected "minutes" as impedance. I even deleted the "Length" attribute from the network dataset. The are no other restrictions like oneway or so and roads are perfectly snapped. Do you know what is happening?

Thank you very much,

Bogdan
