Multiple Drivers Route
Understanding the Multiple Drivers Optimization Type
Route4Me supports two optimization types: the Single Driver Route and the Multiple Drivers Route.
The “Multiple Drivers” optimization type uses a powerful algorithm that allows you to split your addresses into several routes, based on unlimited specific constraints such as duration, minimum and maximum number of vehicles, capacity or time window constraints for each destination.
Click the “Multiple Drivers Route” tab in the route planning advanced options.
This algorithm models real-world constraints and limitations that exist in your business, such as the road-network, drivers, vehicles, and those defined by your customers.
To plan a multiple drivers route, go to “Plan New Route” and select one of the compatible options for adding addresses (Upload a File or Import Data).
The first constraint you need to consider is the “Number of Vehicles.” Route4Me automatically determines the appropriate number of vehicles you need for visiting the set of addresses under each specific set of time windows and capacity constraints. You can input a minimum and a maximum number of vehicles, corresponding the least or biggest number of routes to be created.
Next, you should set the route duration (usually corresponding to the drivers’ working hours) in DD:HH:MM format.
In the example above, the route will be split into a minimum of 8 and a maximum of 12 parts, each with a 9-hour duration.
If the time windows and capacity constraints require less than eight drivers (the minimum number of vehicles) visiting the set of addresses for 9 hours each (the route duration), then the system will split the addresses into eight almost equal sub-parts. That may mean that the route duration may be shorter than 9 hours.
If your addresses require more than 12 drivers (the maximum number of vehicles) working 9-hour shifts, the system will create a set of “Unrouted Destinations” that will appear as a separate route in your routes list.
Setting Advanced Constraints for Time Windows Team Routes
Enterprise subscribers have access to a set of advanced constraints based on distance, capacity or cost, that can be applied to time windows team routes.
– Maximum Distance per Vehicle – When splitting a route into several sub-routes, you can specify the maximum distance for a sub-route. This is particularly useful for routes where you don’t want your drivers stopping for gas;
– Maximum Pieces per Route – This sets a limit to the number of pieces a vehicle can carry;
– Maximum Weight per Vehicle – This sets a weight constraint for a vehicle;
– Maximum Volume per Route – This sets a volume constraint for a vehicle;
– Maximum Revenue per Route – This indicates the revenue limit for a vehicle;
– Stops per route – This allows you to set the minimum and maximum stops a vehicle will visit.
This optimization type also supports routing with time windows.
For these constraints to work, you will need to add additional columns to your spreadsheet file prior to uploading it. These columns must include values relating the constraints for each stop on the route. See an example of how these columns should be included in your spreadsheet below:
