Selecting route choice areas

Through route choice areas Vissim collects the density and number of pedestrians as the basis for the calculation of relative volumes when selecting a route.

You may take into account all areas or ramps in your Vissim network as route choice areas which include intermediate points of the pedestrian route. Or you may select individual areas or ramps to be used as route choice areas.

When you change the course of a partial route and therefore position intermediate points in other areas, repeat the steps.

Select areas with intermediate points as route choice areas

1.  Under the Lists menu, choose Pedestrian traffic > Partial routes.

2.  Right-click the entry of your choice.

3.  In the context menu, select the entry Automatically generate route choice areas.

All areas where the intermediate points of the pedestrian partial route are situated are used as route choice areas. You can select the combination method through which the number or density of the pedestrians on the route choice areas is calculated (Modeling partial routes for pedestrians).

Tips:   Alternatively, you can also right-click the desired partial route in the network editor and choose the entry Generate route choice areas automatically in the context menu. You can also select multiple partial routes and choose the entry Generate route choice areas automatically in the context menu.

1.  Under the Lists menu, choose Pedestrian traffic > Partial routes.

2.  Right-click the entry of your choice.
