Road Impact Model

This model will NOT function on Netscape or versions of Internet Explorer less than 5.5

Adjust the following input parameters to match your population and road situation.

Road Avoidance Behavior

Specify the road avoidance behavior of the animals.

Road Characteristics

Specify road size and traffic volume.

Population Sensitivity to the 4 Road Effects

Choose weights for the 4 road effects.
Values should range between 0 and 100%.
If they do not sum up to 100% they will be automatically adjusted.
