Network Analyst Route Impedence Producing Strange Results

Hi,

 

I am using ArcMap 10.4.1 with NA. I generate 2 routes with the exact same start and end points, network dataset and restrictions. In the first case I use Length as an impedance and in the second case I use Exposure. This is the only difference. For some reason, however, the exposure in the second is significantly higher than the first. In other similar instances (with different start and end points) the exposure in the second may be lower than the first, but the length is actually greater for the route where length is set as impedance than it is where exposure is set as an impedance.

 

How is this possible? Am I using impedance incorrectly?

 

Thanks
