Additional issues. Consequences of the adopted process. There are some zone pairs where there are at least two alternative routes. The choice of route will affect the junctions through which development traffic passes. Small changes in the assignment assumptions may result in significant differences in junction loading. The distribution and assignment has been based on certain assumptions for the values of time and distance. Some of the routes used by development trips in the model may not be considered to be suitable by the local highway authority. In these cases, they may take action to prohibit or deter the movement. This would have the consequence of increasing the loading on the junctions of alternative routes. In some cases, this may result in other junctions being assessed as critical. Sensitivity tests could be undertaken which apply a penalty to unsuitable routes thereby encouraging development trips onto more major roads.
