Using Routal you can assign zones to your vehicles so that those stops that are within that area are visited only by the drivers that you decide.
Now that you have created the zones, you only need to assign them to your drivers. There are 2 different ways to do this:
1. From each zone
Open the Zones right panel from the Zones section (from Project settings) or within each plan. If we do it from Zones, the changes will be reflected for all future plans, while if we do it within the plan, the change will be applied only in that planning.
Procedure
Double click on the zone (or right click > view details)
Select the vehicles to be linked from the drop-down list.
2. From your vehicles
From Drivers > Vehicles (and they will be assigned for all your future plans as long as you do not modify it), or within the plan (only for a specific plan).
Procedure
Double click on the vehicle.
Select Restrictions.
In Zones, assign the zone/s from the drop-down list.
